Here is my car,I did 2 runs in 3rd and then a run in 4th so the car was heat soaked on the 4th gear pull,these are also sae corrected.

I made 550ftbs sae in 3rd gear on pull number 2 and 583ftbs using 4th gear on run number 3.

The guy said if I would of just ran it in 4th gear on the first run with a cold blower it would of made 600rwt and over 500whp SAE corrected and another 10-15 more using ST correction factor.

Nice numbers! Correct gear to do the pull would be 4th though? 1:1

Nice numbers, are you still going to go to a bigger pulley?

skratch77

I think im staying with the 178 and just going to try the 80mm tb

And yeah 4th gear is 1:1 tbal

Hey Skratch, you wouldn't happen to have an AFR graph that is a bit more visible for those pulls do you?

The shops o2 reads a little on the lean side from what I was told,so Im around 11.5 at redline and not 11.8 like it shows.

That is the best pic I have and I can try to get the raw numbers.

Cory from kleemann said he has another car with my file and its 11.5-11.8 up top end so this looks really spot on to there car.

you have to keep in mind that this is run 2 and 3 and the car was not dumping fuel because it was running safe timing up top end.

Edit this was run number 1 on cold car in 3rd gear and run number 3 on heatsoaked car in 4th gear,I just looked over all the sheets and got them confused because we have some in ST correction and SAE correction and mixed them up.

so this A/F is from a cold car to a heatsoaked car.

I am assuming no problems from dynoing the car in 4th gear? You did not hit the speed limiter in dyno mode dynoing the car in 4th gear?

skratch77

Took to 6300rpm or so and no rev limit was hit.

skratch77

Looks like 5800 rpm in that pull because a told him to let off.no need to blow up my car on the dyno lol but it would of revved to recline.

Not you Skratch, but why anyone dynos in 3rd regularly is beyond me. You dyno 1:1 and that's 4th. Not sure where all the "dyno in 3rd" guys are coming from.

It was the only way we could get my car to hit 570wheel down in LA. They tried and tried and finally I screamed at them DYNO THE ()&*)(*&&in thing in 4th. Sure enough....we got it.

Jakpro, this was covered in another thread, but is still good information, so I will post it again. I asked a tuner why they dyno in 3rd, and there were a number of reasons.

4th will down shift (even in M) if you get on the throttle (this was shared by another member)
4th gear takes forever to rev to redline, adding to heat issues.
If car does not have speed limiter disabled, it will cut out at 155
Some dyno operators do not like to take wheel speed to 185+ (They say: :"Dyno doesn't like that"

..and last, most important (to me): As long as you use the same method to test +/- changes, you can use either gear, 3rd is easier on the car, and is quicker, but will not yeild the highest number possible. Then, he said something about the track.

Typically, when SAE is running 1.01, STD will be 1.04. Given that difference, your best run would be:

STD Correction
505.58 HP
601 TRQ

Nice numbers!
(PS- SAE is generally the correction people use, however any comparison of dyno numbers between cars and dynos is just a big fight waiting to happen. None-the-less, your car is putting down great power!)

I put down 436 hp and 470 on the same dyno, on just an intake and exhaust car.. So skratch is has 130 rwtq on my car.. That thing is scary fast

skratch77

Its weird as my brothers 04 e55 kept downshifting and my 05 wont downshift in m.

His car will also up shift in m mode and mine will bounce off the rev limiter and wont shift.

On the other hand my car is almost impossible to do a burn out and he can roast his tires till they blow up

Nice numbers mang.

skratch77

Ill have new numbers with an 80mm tb soon
