The car was slower with the single plane on it unfortunately, so we returned it back to the stock intake.

If you were going turbo, or spinning it to 7500-8k, then it would make sense. It doesnt with the current setup.

 

real impressive

You saied it is a 415 ci, so it is a LS3 block, thus, what is the bore & stroke?

 

not sure on block

stock intake and just milled heads no port work or valve job

I wonder what a ported intake and tfs heads would do

 

Having a similar issue with my 416 ls3. Peaks early 5800-5900 and falls fast after 6200-6300 rpm. I also have a ls3/l76 intake.

I would think a ported fast would make a huge gain.

I would like to have a ported Fast 102/102 by end of year.

 

Let me know the results.

 

This combo ran
10.57@130mph. N/a

10.00@140mph on a 150shot

 

Very nice. What were your 60ft times? race weight?

 

1.5x 60fts

I'm guesing 3400lbs. Very minimal weight reduction

 

Similar results as mine. I took mine out for fist time. Mine is a a4 ss4000

10.66 et
124 mph
1.42 60ft
3,550 race weight

Car is just dying in upper rpms.

 

I am gonna need land ...

we need a fall get together...

 

That sounds like fun

 

What r the specs of your 416?
What Rpm do shift at. Make peak power also

 

are those numbers stock intake or the ported one u did?

 

That was with the stock intake. I never got to dyno with the ported intake.

 

nice numbers man

 

I would think the ported intake would be 10-15 rwhp over stock. I would think a ported fast 102/102 Would be another 20 rwhp more and carry out some rpm.

 

Some more Rpm would b good
