Mark and Marty, after talking to the guy who owns the dyno...I am pretty confident the dyno is fine. The problem is the correction factor. So I will use uncorrected numbers to compare before and after. The mods are done today anyway ...just a little break-in time and then....

 

it will be interesting to see what it will do after u put the bolt ons.....
good luck,
mark

 

First time EVER at a drag strip... My 60' was 2.23!!

Got the uncorrected dyno sheets attached. This seems much more reasonable.

 

Thats more like it. Why is the afr crossed out?

 

Thats better. Your dyno operator has a crazy correction factor.

 

Turns out the correction factor is indeed the SAE correction factor, but it is certainly not appropriate for our turbos!

 

Cool! Now after the mods you'll be @ 474HP, which hopefully will still shock you

 

New numbers seem exactly right. Didn't you say bolt on s were on already? What fo you think? If it is kevins new stuff you may still be breaking in. Don't shortcut the brak in of a zero clearance turbo or it will not last. Let us know what you think. Good luck.

 

Yeah, I feel a little better also. Don't have the car yet...probably next week. Found a couple of minor things to fix while we had it apart...and then doing some regular maintenance stuff...then, as you say a nice easy break-in for the first 200 miles. After that...we'll dyno agin!

 

I had Kevins stage 2 turbo's and did 100 mile break in. After the first 50 miles I slowly added boost. Obviously with the 100 miles you should do at least 5 shutdowns (eg driving the car and shutting her off)
