that,s what Peter from Pure Turbo ( pureturbo.eu ) said what is possible, i know a dutch forum member who has the same car like me, gets exactly 500whp ( 550hp) with only 98 fuel.

i Spoke with Peter ( pure turbo ) and he sees no problem with the sport cat 200 cell

Friend of mine ( who has same car and setup like me ) has already the pure turbo 800 with bootmod 3. they did dyno the car around 550ps

after that he went to mosselman ( netherlands tuner ) and they reprogrammed the tuning, they where busy for 2 weeks finetuning, as a result the car has now 600ps ( 98 gas only ). he will get his car back after tommorow, i wait for his comment and dyno figures

I’d loved to see real world 600 whp dyno. I’ve personally never seen one, not saying they aren’t out there, I just haven’t seen one.. specially on a TU pump

All depends on the fuel and on the Dyno , 521whp seems low... we put this car on a other dyno and there was 542whp. if running on 102 octan ,we sure get 550whp... a lot depends on the octan rate.

600whp dyno i saw ( i also googled it ) but this dyno was on 20psi , the 600whp dyno i,m not sure how much pressure they did use, wasn,t clear also by the other readers.. also i think above 550whp you need at least the stage 2 fuel pump !

Nothing wrong with the cat , just for sure i,m replacing it together with the pure turbo install next week.
But i want to know how the cat is looking now after 10000km , to give everyone an idea about the quality ( or not )

just brought my car to pure turbo,, will be next week saterday ready. Friend of mine just was ready with a custom tune with his pure turbo, they managed to get 600ps , but the first 3 gears he has a lot of traction problems, so they will limit the torque at the first 3 gears.

i also think without other modifications 570ps is the limit on 93 gas, if you want more ps then you also should change clutch and other components. ( the 570 is measured on a european Dyno, i know some US dynos are less accurate ( they measure more ps ) )

Today Peter from Pureturbos.eu is starting with placing a new pure800 turbo for my car, i also decided to replace the cat with a catless VRSF. together with stage 1 dorch fuel pump and new NRK ignition plugs..

before replacing the car was at his Dyno, i already had stage 2.
it was showing around 400whp. let,s see what the car can do after the upgrade..

First measurement is ready, car is very sensitive for octan rate. but with real 98 fuel i almost got 520whp .

with 102 i think 550whp is possible , saterday i will pick up the car, but the tuner said the car is running very smooth..

What I find interesting is how much relavent information is always absent from these threads. Sure HP, and Octane is important, but so is boost, timing, air volume (intake), plug gap, injector timing, and more ...

Anyways, just posting to follow
