This 427rwhp result is equal to around 499rwhp on a US dynojet dyno. This run was made with 18psi and 98 octane pump fuel. Peak power was between 7200rpm and 7500rpm. This was my qualifying pass.

This is my finals result from the HP Heroes. I won the twin rotor turbo/supercharged class. This figure was made on 22psi and again bettween 7200rpm and 7500rpm. 433rwhp is equal to approx 506rwhp on a US dynojet dyno. The reason the gain from more boost is so low is when HITman tuned it, above 22psi he has retarded timing to almost TDC to try and safeguard against massive engine failure due to overboost. Another run on 23psi netted less HP.

HITman says that I could have got close to 450rwhp (525rwhp on dynojet) but this would have put the engine at risk, so we didn't do it! In the end the next closest competitor ran a 414rwhp (485rwhp US dynojet) on 20psi but it was nerve racking waiting for him to run!!

I got a nice trophy and a cheque for $300!! WOOHOO! And it only cost me $30 to enter!!

 

way to go ive already read all this info on fast fours forum.

All the 1st geners here would apppreiciate that kind hp from a 1st gen.

 

congrats. You have pioneered a good lead for us 1st gen guys. That car is definately a monster. With that power i would like to see were it breaks into the tens. Did you do anything new besides tuning

 

Congrats! just goes to show what ALOT of hard work will get yah, keep it up!

 

your nuts!!! but those are some very impressive numbers.

 

Just a set of B10EGVs. HITman tuned the car last week for high boost and it worked out well! The car is an animal on 15psi, haven't had the nerve to turn it up to 20psi on the street!!

 

Did u ever run 20psi @ the track before? Are their going to be anymore upgrades to the car.

Or do you think that you are tuned to were u want to be right now. Thats a whole lot of HP for that car. Thats got to be a nice rush (feeling).

I see u went to a colder plug!!

 

I ran around the 20psi mark when I ran 11.1 @ 125.

Possible mods in the future are a smaller exhaust housing on the turbo as spool up time at this stage can be measured in minutes :p

A new box may be on the cards too, but thats not a mod, thats just a fix

 

i need a turbo...............

 

Get a video of that beast on the dyno or somethin!

 

Funny you should ask....
