Default A4, High Stall, Cam only 405rwhp

Here is my graph. I dyno'ed 370 rwhp before I added the headers, ported TB and went from a 3300 stall to 4000 stall. Conveter was locked.

They did. We are at 2300 feet, so it was actually a couple of HP higher.

Thank-you! I only had 3 runs and was getting the AFR right so all runs were the sam (locked). I would like to know that too though. Next time I will try and see what it does unlocked.

Your sheet is in STD numbers..
Thats not SAE corrected numbers redhawk....

A/F IMO is too lean too...
Its over 13.2 threw the whole run until 6500 and then it drops.I'd be careful running this car at the track as its gonna shoot up alittle bit.IMO it should be tuned in around 12.6 to 12.8 MAX

Yes, I know that chart does not show the SAE numbers. But, as stated before the SAE numbers were slightly more. This chart was corrected for altitude and weather as that is why this chart was lower than the SAE one is what the operator said. And I tuned the car for 12.8 after that run, need to get you the final run, he didn't print that one off as we were tuning a lot of cars that day and it was quite hectic. As you would know, when a car is that lean you don't gain anymore hp, it is just dangerous there, so the numbers didn't fall off after the afr was corrected.

I have the Yank SS 4000. I haven't had it to the track yet to see how it does, but on the street it has as good manors as my Yank 3300 had.

How can you be running your cars so lean!? Mine is at 12.1AFR and is silky smooth to drive. More fuel equals more resiliance to transient lean conditions and too much spark. With the abuse we give these engines I much rather run richer than leaner.

I think most go for 12.8 for N/A, that is where mine is at.

If the dyno correction software is setup correctly,it will always read for correct weather,density altitude?Thats why Dyno-jet sells the software as does all the other dyno companies.Every Sponsor on here dyno's car in SAE correction,thats the what its done...

I'm not trying to knock u or your numbers,there are very good but I still think your A/F is way lean and if u brought them back to say 12.6 to 12.8 (U did say they are there so thats good) they would be safer..Post up your new sheet so we can see the correction,a/f and locked verter in SAE...

Those are some nice #'s a unlocked converter should be around 380 or so and with the right setup (suspension, converter, weight reduction, etc..) it should run 10's
