I Gave V2 what it needed and WOW

I know every countries Dyno's read differently and correct values differently but the main thing when measuring power is measuring on the same dyno and with the same conditions.

I have attached my first Dyno's that i took with V1.47 95 RON fuel no air filter, we measure in KW and NM. 290kw and 570NM. The KW Graph shows run 1 my old run with 1.47 and run 2 is V2.Today i did another dyno run and gave the V2 exactly what it needed more air "K&N Air filter" and more octane, only 102 RON fuel in tank. Max power up to 309 KW an Torque flew threw the roof at 670NM at 96% settings. These numbers are corrected for sea level.

I asked the guys not to correct but they said that they couldnt change the dyno setting as they had other cars ready to be tested.

All i have to say is wow the car neeeeeeded the air filter at this high altitude and its loving the high octane!!!!!

Congratulations. It seems we all should see with which intake mod Shiv comes up with. 309 KW = 415 hp and 670 NM = 495 lbft. Numbers are @ the wheels ? You had 380 hp and 420 lbft with v1.47 already. Do you have other mods ?

wil confirm tomorrow but i doubt they are @ the wheels far to high numbers. But at the very least i know there was an increase.

With 1.47 that was the only mod now i have K&N air filter and running 102 RON octane.

Subtract 12% and his dyno will be inline with everything else we've been seeing for the last few weeks. I do wish his numbers were uncorrected though. That dyno is most likely overcorrecting his power and torque.

Im going past there tomorrow ill ask if they can print me uncorrected numbers i also would like to compare to everyone else on the forum and by them correcting them you cant compare apples with peaches. But at least when i compare it to my last dyno there was a drastic increase and to me thats what matters...

The question is how much boost you are running now.

Looks that you were right. V1.47 had more power low down (at 2000rmp) even without the K&N and race gas. It would be interesting to see if you are able to get the same low down figures with V2 without the K&N and race fuel but by having the 100% settings instead. Or did you say before that 100% was not any better than 96%?

(P.S. The figures as such are seriously inflated as they should not be corrected, but it does not matter since we are interested in the difference)

Thats what i was saying without the air filter and high octane V2 would have less power than my V1.47 "at high altitude that is" and i agree the figures should be uncorrected and ill ask them if they can print new ones tomorrow.

Being at this high altitude 96% or 100% setting made no difference on my boost as the turbos where overspinning.

No way it was at the wheels. 495 wheel ft. lbs of torque? Nah.
