Rule 1 - never believe any US dyno figure.
Rule 2 - don't get hung up on dyno figures...

If you are getting X boost, and the car is mapped with decent timing and AFR then it will be fast.

I was told by my tuner that the map he did on the greddy emu was very very safe, im not getting hung up on the numbers ,but - 2 degrees of timing can mean 40hp differance in the tune, when your no where near to detonating .

As i understand it you tune untill you get DET then add a bit of timing to be on the safe side ,not a LOAD as in my case .

Im not asking for a 100% on the limit tune as Mase will give but a 90% tune.


I chose my setup with the gt3076 because my research told me i could reach the (in my head goal) of 500whp number at 15 to 16psi.

That -2 degrees was just an example on my car lee, i had it running safe timing as TBH i wouldnt of known what it should have been when i upped the boost, but yes -2 deg dropped 40BHP on my car.

All i know was when my car had had a decat and AEM V2 intake it made 231BHP on the dyno, now it makes 393BHP using the same dyno but differing conditions, if anything it was a better day when it made 393BHP.

My s2kip made 350whp on Surrey in its current state (12psi on vpower) but it pulls about 1/2 a car length per gear against the gtr. ( rolling start )
Huh, your saying your car pulls on your GTR?

Who was driving it Frank Spencer?

But you don't get transmission/belt losses from a turbo.

A turbo is more efficient than a supercharger so per boost, you'll get more power from a turbo.

Turbo produces full boost early on, but super has better response.

A 350whp 1250kg (280whp/ton) S2000 should be a match for a 400whp 1750kg (228whp/ton) GT-R.

Car is on dyno now, small issue this morning - Honda didn't put the VIN inside the ECU, so we had to recovered the car from our workshop to Honda to code the VIN back in for us to access into the ECU.

Is all ok now, finger cross!

Small problem, the 3 bar map sensor they sent us didn't work. Ordered a new one from Hondata just now but we won't have it till Friday so we have to wait another few days until we can get it map over 7000rpm now.

So far we only got 400bhp at 7000rpm...
