I know that there are some before and after dyno runs with the base porting any one have the link or have the Dyno runs they can post

 

just do a search

 

I couldn't find my site reference to the dyno pulls so you've got mail with the data.

 

I did a search but, after going in most of the posts it gets old real quick! almost every post has a porting pic but, no results just "I felt a big differance" thanks jim It has not got there yet but, it takes a while to go through.

 

Though the image isn't very good I just put it on my site:

Jim, are those accual numbers? If so, what are the numbers, cant read em?

 

Sorry about that quick and sloppy pic; you've got mail.

 

I thought you were supposed to lose a little bottem end torque with that setup?

 

Not according to my references and that "dyno pull" that I recently put on my site just for reference. The guys who have done this mod said that it "felt" a little stronger at the low end too.

When I get some dyno pulls after installation I won't have any data below 3,200rpm since it's going into an '88 Vette with an A4 tranny. So, I'll have to look to my SOTP dyno and 60' times for low end clues. I would like to see someone do dyno comparisons (actual dyno curves) with this mod and a 6-speed so low end torque could be shown.

Also I'm wondering if I'll realize with same benefits with a nearly stock cam (1.6RRs) and unported stock heads.
