I did, but I didn't use quite as much weight as you did. Why don't we just assume he weighs a lot and plug in 3450 in there and give it another 20whp?

In other words, it's pure speculation...and detonation.

 

Making 450 whp on a stock evo turbo is impossible. The turbo runs out of steam and cannot hold the boost necessary to get that kind of HP. The most i got out of a stock turbo on race gas at close to spiking at 29psi.. .was 405whp and 401 ft lbs. This was with AEM and race gas. The car ran 11.7 @ 118. Any more boost on those pistons your just asking for problems. As far as boost up top, that turbo will only hold about 23psi..around 6500 rpms. NOT POSSIBLE>>>>>

But what if you tried really hard? j/k


I agree. That kinda power is not possible with the stock turbo. No matter what bolt-ons you use with it. All those exhaust gases still needs to squeeze through that tiny turbine housing on the way out. Holy backpressure!

Leon R made 450whp/455tq with a small 16g years ago. NOS was of course the secret. Its already been posted twice. Maybe three times is a charm?

 

but after all..... ITS A BIG 16G

 

450 whp cannot be done due to the limitations of the stock turbo. The compression housing and valving cannot withstand that type of force with out dangerous levels of boost spiking and backpressure. 350 whp is I think the best / safe whp # but if tuned properly. Above all seek balance with your cars. The Evo a phenominal road race car that puts most cars in the exotic class to shame. Tune for balance and enjoy your ride, don't be one dementional and focus on just horseower. So many talk 1/4 times, very few talk lap times. That is what makes a driver. That is what defines the Evo...the road race....aint that right my fellow desi brother (Shiv)?

 

And I am reffering to a dsm small 16g which is rated at 505cfm. An evo8 16 is more in the area of 625cfm if not more. I am surprised at Mark, and Shiv come on here and say it is not possible to make 450whp with evo8 turbo. Shame on you guys.

 

No need to compare a car setup for drag racing to a car set up for lap times. Two worlds of different tune. The drag car only has to make power for 12 seconds. the lap car has to make it for two minutes. best way to talk about horsepower being made and the best way to compare it is by the 1/4 mile run. no such comparison exists in the autocross world since everyone would have to go to the same track.

 

Hint: It's not the compressor side which is limiting the hp of the factory EVO turbo. So those pretty compressor maps don't mean diddly

Approx. 495 whp was generated to run those traps; but not on the STOCK turbo.

As has been mentioned, 370-390 whp is the limit of the stocker/stockish turbo no matter what parts are thrown at it, IMO.

 

Hint: your burying yourself even deeper. the small 16g runs a tdo5 7cm. If you want to believe the larger evo 10cm is not capable of 450whp go right ahead. but its already been done with a less capable engine and smaller turbo. I am done here.

 

dude i got everything but head work, built motor and turbo and im only layin down 328hp 328 tp to the wheels on 92 didnt try on 115 racegas but Quantum is doing an AMS GT35RL kit and the water injection kit and AMS claims in the low 500whp range on stock block so we will see....

 

Well, factory numbers for the car are 3260 with a tank of gas. Subtract about 60 lbs figuring he is only running with 5 gal of race fule... that gets you to 3200. Now add the weight of the driver, helmet, laptop computer. For me that gets you up to 3460 (its an old heavy laptop... yeah... thats it!) For me my weight reduction consists of the light weight Buschur Racing exhaust system, and the light weight battery kit. That gets me back down to 3400 lbs.

Now we need to know what else he has removed, and replacement hood / trunk lid with carbon fiber, and also weight added for roll cage and all that. If can easily believe he is 100 lbs lighter than me, shoot... I could even go 200 lbs lighter if he is a skinny guy and did some seriouse parts removal on the car.

What were you figuring? The car is stripped down to bare metal with an engine and one seat and tops out at 2500 lbs with the skeletal driver then yeah... he is only making stock HP! LOL

And for you evo8 guys who dont know who Leon is. He holds the 14b (405cfm/6cm hotside) 1/4 record. 11.64 at 116.5 no NOS. I believe his track weight is around 2850-2900 range.

14b typical max 270whp
s16g typical max 340whp
evo 16g typical max 400whp

 

Are you saying that porting the stock housing now means it is an upgraded turbo??? Not in anyones book but yours!
