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>>>>>

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!

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)?

My race weight is 3400 lbs with me in the car, so if we assumed 100 lbs lighter for him and a 124 mph trap speed that gives us 495 wheel hp on a dynojet or dynapack.

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.

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

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