watching a ford commercial about some car that they have with a turbo. other manufactures have cars with turbos and even superchargers like in the dodge neon. to keep their cars reliable there has to be a safe limit. for tuners, a stage 1 turbo kit kicks in around 5-10psi.. surely manufactures wouldnt want to mess with a stage 1's power due to reliability, or would they...? | ||

i believe my 85' Dodge Daytona was around 6-8psi stock. I found a way to use vise grips and squeeze some kinda tube(cant remember, i was 16,lol) and bumped it up to 12psi... Man i will never forget the smokin burnout i did completely around the entire Hardee's parking lot in a 2.2L 4 banger!  | ||

The most I have seen on a production car was around 14 psi on a turbo. Superchargers are around 5 or 6 psi. Ford's new turbo engine they named Eco-Boost. Not sure what is eco about it though. It is direct injected and turbo charged to 12psi with a static compression of 12 or 10 to 1. I forget but it is pretty high for an engine with a turbo on it. They can do this safely on pump gas with direct injection. | ||

2009 WRX is just shy of 14 lbs.  i believe my 85' Dodge Daytona was around 6-8psi stock I owned one in 88. It had close to 11 lbs | ||

I had n 86 Dodge Shelby Charger that stock was like 6-8lbs. but after I had it leaned on it would flash to 16lbs. and hold a steady 14.5lbs on premium pump gas only. It surprised a lot of people. You can google 2.2 dodge turbo racing and find all sorts of neat stuff (Message edited by S1wmike on August 24, 2009) | ||

BTW, That picture was taken in 91. I scooped the hood,bigger turbo. It wasn't intercooled factory but you could get it through Direct Connection. Mine was done as was the tranny. Fun car and fast for a 4 cylinder back then. Nothing like the WRX capabilities though. | ||

I thought this was cool. A friend has a turbo VW and was talking about this. I wonder how legit it is. "The turbocharger used on the 1.8T VW's is the Borg-Warner KKK03. The K03 turbo is a smaller turbo, capable of spooling up much quicker than other traditional turbos. Stock, the engine/turbo combination produces 150hp, with 150ft/lbs of torque that kick in at about 1750 rpms; all at a safe 7psi. The beauty of the engine is that torque stays on all the way through the rpm range, so full torque is available through almost all of the rpm range. This makes the car a joy to drive, with smooth consistent power always available. Now add chip tuning to the equation. For about 500 dollars, chip tuners modify your ecu to perform at different levels. In the past, this meant a few percent gain in hp. Boost management is handled by the ECU, so chip tuners are able to generate massive amounts of power by modifying the stock programming. On the stock program, the turbo generates about 5-7 psi. For example, with the GIAC 1.1 bar chip, your car will now make about 15-16 psi of boost pressure. Under loaded conditions, the GIAC can spike at up to 20 psi. What does this all mean? Increasing your power by about 33% with just the chip makes large amounts of HP and torque available immediately. HP is up by about 47 over stock, and torque is increased by up to an amazing 90 ft/lbs!!!! For most drivers is simply the easiest, most effective power upgrade available." | ||

High performance Porsches (eg GT2 etc) generally run fairly high boost. The 2008 GT2 apparently runs 20.3psi, which is 5.8psi higher than a garden variety Turbo! I'd guess you'd have to be fairly careful what fuel you ran in them. | ||

yeah i loved my Daytona! wish i would have kept it. Now i want one of these...  OR...  I always get.."WTF you want that POS for?" I just have to laugh it off. I beat alot of cars with that little 2.2L | ||
| Froggy |
The whole V8 like power and performance, V6 fuel economy and emissions (assuming you stay off the boost!) | ||

Ian, I miss alot of my old cars but the Daytona was fun. I love my WRX,having just about as much as my bike for sure. | ||

I have been a in to turbo cars( dodges mostly) since before getting hooked on Buells. Went through almost every K-based 80-90s turbo dodge that was made. datonas, shadows omnis, rampages, changers, lebarons, spirit,, k-car, k-wagon, Lancers, tc by Maserati and last but most important. 89-90 turbo minivans. these are the where the fun is at. especially with a factory 5 speed. Most of these cars ran 6-11 psi stock depending on intercooled or non intercooled and other factors. all could be turned up to 14.7(2bar) in less than 5 min for less then 5 bucks. hands down, a moderately modified turbo minivan takes sleeper to a new level. todays modern turbo cars can come from the factory running upwards of 18-20 (09 Evo and 08 Masda speed 6) psi thanks to the new more sophisticated electronics. dont get me started onn urbo cars. i have projects hibernating in the garage wating for time and $$. maby when my daughter goes to college ill get to them.. till then the TIII(?) waits. http://www.turbodiy.com/Mopar%20Pages/Mopar%20Imag es/Videos/cc_van03_2.avi | ||

I got my Father hooked on the boost bug, and when I wasint looking, he went and got WAY in to it. hes a bit of a mad scientist. http://www.turbodiy.com/ These days i prefer motorcycle racing. Seth | ||

Shelby GT500 makes 9-10 psi, depending on the weather. That motor is built to handle it and then some. Same is true for the ZR1. By comparison, my TRD Taco can make 6 psi of supercharged boost on the stock pulley. But in warm weather I barely hit 5 lbs. Bone stock turbo diesel trucks can get near 30 psi.

This is my new toy. With a little tuning it'll get 19 lbs. to 20. Thats gonna get done next year. For now just wheel's,tires springs,and exhaust is done. The thing is quick though.  | ||

The Mazdaspeed6 and Mazdaspeed3 both run 15.6lbs of boost from the factory. | ||

Tuner here, I have been playing with forced induction for a while... Daytonas, Omnis, Talons, Eclipses, WRXs, Audis... and so on. When dealing with a long block that was not built for forced induction, 6psi from a turbo is a lot.... when you get into engines made for boost, you can really crank it up. My 97 Talon TSi AWD has been pushed up to 22psi before. It greatly depends on your setup. Flow bench the engine, find out the volumetric efficiency by RPM, then get a turbo that flows (on the exhaust side) at an efficiency level complimentary to the engine. Then, depending on the turbo shaft speed, selecting the correct compressor side. There have been volumes written on correct turbo sizing, and a few different doctrines as well. | ||

Bads1 - THAT is a sweet car. I bet it's lots of fun!! | ||

Off topic,sort of. Hot rod tractor pullers go up to 300 psi boost!466 cid International diesel tractor,stock block with double, triple and QUAD(!) turbos. Good God! Course,they are getting upwards of 3,000 horse out of a 200 horse engine.......... | ||

The Grand National from the factory had 14-16 PSI... if you loosened the wastegate bolt and adjusted it yourself then you could get a stock motor to push 20-22 PSI with good fuel and a chip. Mine which is far from stock is alcohol injected 72MM turbocharger and I launch at 22-24 PSI and then cap out at 32 PSI. Makes for a nice wheelstand. | ||

My favorite turbo    | ||

heehee...boost. Aside from my Buells..one of my favorite topics  I still own the first new car I ever bought - a '91 Daytona CS Competition Package with a 2.5 turbo. Factory sheets show 150 total units built, 26 with my options. I upgraded from the factory Mitsu turbo to a Garrett .48a/r and had it intercooled for a while, but put the radiator back to stock (no IC) for showing. The mitsu spun up faster, but didn't run as much boost at higher rpm because of its size. Factory non-intercooled blowthru intake cars were set for 7-9psi. I ran that as high as 18 with the Garrett and IC on it, no issues. I also own an 87 Shelby CSX. I popped that one on the track in the middle of a 10 second run, at around 32psi. Timing was just *that* much too agressive, whoops. Melted #3. That car was intercooled and had a 70-trim garrett with intercooler and bigger injectors (and it will be again). Stock was 14.7psi with a .48 garrett and factory IC. Americanmade - I actually have an 86 S project if you're interested Complete, all the bits are there, rusty doors but the floors are good...just needs title work, all I have is from upstate NY and it shows a lien that needs to be cleared up. It's paid, the lien is 14 years old...I'm just tired of fighting with NY. My daily driver used to be a '91 Spirit R/T with the Lotus-head 2.2 16v turbo (TIII motor). Stock intercooled, that car was 14.7psi. I ran it for years on 'street' boost of 18psi with nothing more than bigger injectors and a 2.5" mandrel exhaust. On the track and race fuel, I'd crank it to 25 with no problems. I'm actually getting ready to rebuild it - a buddy bought it from me, nearly 200k miles and the oil pump gave out. My other baby is my 89 CSX-VNT. First factory application of a variable-vane turbocharger. The housing had vanes on it (think pinball flippers) that were computer controlled for their angle to the turbine wheel. They could either point at the wheel, increasing exhaust flow to spool up the turbo faster (low RPM), or open wide to make a larger housing area for higher rpm boost. Pretty cool system - turbo lag is NONexistant. There's quite a few diesel cars and trucks using VNT tech now...but this thing was way advanced for 1989. It was also stock at 14psi, but I have it set around 16 (with an upgraded turbo - went from a VNT25 to a VNT60, even Carroll Shelby looked under my hood one day and said "I didn't put one THAT big in there, did I??"). I don't go too radical on this one, only 500 total built, 15 with options that mine has, 50k original miles, hand-autographed by Carroll...it's my baby. Don't wanna blow it up by being boost-greedy, lol. Most cars that are factory-boosted are overbuilt. The 2.2 / 2.5 Mopars are a prime example. MANY guys in the turbododge club are running astronomical boost levels with stock blocks and rotating assemblies. ARP head and main studs are a good idea over 20psi so you don't lift the head or shift the crank...but very few people are using non-stock cranks, rods, blocks, and even pistons. Full-on racers are using custom slugs, but for the most part the OEM 8.5:1 pistons are good for lotsa boost. Head porting is always a debate, as is cam profile...but for the most part boost levels are driven by electronics. The system gets more complex once you go over 14.7psi - 1 BAR of boost, or 2x atmosphere. A 3 BAR system is more complex, and for the advantages the driver gets (and the relatively few numbers of drivers who actually want it), the makers tend to go conservative. Most makers limit non-intercooled cars under 10psi for detonation reasons - pressurize the air, it heats up. A LOT. Over 9psi or so, you can get detonation/preignition just from the heat - and at boost, detonation damage is exponentially worse than at atmosphere. Witness my popped '87 - I had less than a half second of detonation at 32+psi, and there's a hole in my piston from it. And that WAS intercooled. But intercooling - at 2bar levels, anyway - helps bring the intake charge back to normal temps. It adds a little lag because you have to fill all the ductwork with pressure....but a split second lag is a small price to pay for pistons that don't have holes in 'em. Our '05 Cummins Dodge 5.9 24v? BONE-STOCK, runs 30psi. Diesel's are different,though...you canNOT give them too much air. | ||

Ratbuell, Give it some propane. But if you start playing with it too much the clutch will go away. MorePowers, I like mopars, SRT version of the Caliber is pushing 300 ponies. (4 banger with boost) Not a WRX but nice for a grocery getter. | ||

I have a 2006 Supercharged Cobalt SS. 12.5 lbs of boost and 9.5:1 compression ratio. In 2006, that was a good amount of boost, especially considering the compression ratio. Sounds like things are moving in that direction. Good stuff! | ||

"surely manufactures wouldnt want to mess with a stage 1's power due to reliability, or would they...?" Just depends on whether or not it was planned for. When you get into trouble is trying to squeeze out more from a bottom end that wasn't designed to handle the pressure. ~SM | ||

The 'Eco' part of the 'EcoBoost' nameplate refers to the fact that the engines are intended to be used in place of larger displacement, less efficient engines. Use a turbo V6 instead of a larger V8, that kind of thing. They are also developing smaller versions to be used in mid-size and small/compact vehicles - a 2.0L I4, for instance. The EcoBoost engines (known as GTDI internally - Gas Turbo Direct Injection) in the 2010 D-Cars (Taurus, MKS, Flex, and MKT) make about 365HP and 360ft/lbs, but only get ~1-2MPG worse than the standard V6s. The Taurus SHO with that thing is a rocket. They took the Taurus and Flex equipped with them to Milan and were pulling sub-13s (Taurus) and sub-14s (Flex) 1/4 mile times out of them. Not too shabby for a people mover. | ||

Mine only came out of the garage for special occasions. Deer hunting wasn't one of them. I had the turbo "tweaked" on mine and ran no mufflers, just the cats. The best thing was it would do about 140 mph or so and you could do that with 1 finger on the wheel drinking a diet pepsi. The faster you went, the smoother it was. At the same time frame I also had a 87 5.0 Mustang GT, it was faster to about 75 but then the TC would BLOW by it and just keep going. The GT was scary at 120, both hands on the wheel. I had a guy in a Fiero GT try to race me once, on a road with a couple sets of S curves, that was a laugh! |
