Limiters off ECU very conservative 295rwhp RB20

Hey Ben, Congrats man thats very nice power !! RB20s still rock ! 12 years on

One suggestion though, turn boost up a little higher say 1.3 - 1.4 bar.

On mine from 1.2 to 1.4bar really starts pulling hard @ 1.4.

cant wait to put the Rb26 cams and pulleys. Gotta do the clutch first tho..

yeah i plan to get it on the dyno again next week before WSID on wed night, I might just do one power run on high boost, but i get a little scared, this is my everyday driver so i need it to run reliably

But like i have said before, i need to have a dyno print-out with over 300rwhp and my name on it. just so i can say i have over 300hp

what does everyone else think about running around 1.4 bar? on a stock RB20 with std headgasket? i was considering running the 1.2bar when i race, but for everyday i only run between 0.8 and 1.1bar.

Quite a difference between my car and Bens even though we have the same turbo but I have a rb25det.

Anyone wish to comment?

What boost were you running Mark, Bens car has the goods on you from 3,500 rpm up?

Less than 1bar.

These are the modifications ive done to my car

MRK25T you need to let it open up, these turbos are designed to run highish boost to reach their efficiency peak @ 1.3 - 1.4 bar...

theres a shitload of power to be had from 1.0 - 1.4 bar...

The next owner can boost it more, I couldnt afford a new engine if it blew so got it tuned acordingly. The tuner at Procar did a great job with the car, it is very smooth. Notice how straight he got the AFR.

They are a great turbo, much better than my high flowed standard turbo.

yeah the A/F ratio is awesome on yours! i need to get mine like that.

was it Paul who tuned your car? he was very helpful and knows his stuff, he showed me some stuff on a 900hp NA V8 he recently built! imagine having an NA 900hp engine!

I really need to invest in a PFC! anyone got one cheap for me? hehe

yours will pull some awesome numbers once the boost is in mark.

1 psi more boost will tip you over 300rwhp easily, i reckon have a go

No, a specialist tuner came in to do my tuning at Procar.

WHo was the tuner mark? Dont be shy.

Paul from Procar will tell you. He doesnt do any joe shmoe off the street. He tunes the car only if you are sitting in the car with him the whole time and explains everything. I dont know cars, but I did a fair few units of physics in my science degree and it all made sense to me.

The car is no longer mine, sold it this afternoon.
