I am sure this has been asked but what are some of the fastest 1/4 times with long tube runner set up with out siamesing the base or the runners? what i want is to run 12.50 n/a with LTR setup if this is possible how are you guy setting up your engine?

 

what are you running now with the setup you have? I see some good stuff in your signature...

 

I would like to know what you run now too. that is not a bad setup you have there. you should be low 13s now right?

12.7, niiiiiiiice.

 

great 60 foot also

 

I didnt get any tuning in before i ran but the best so far is 14.4 at 95mph with 2.2 60' keep in mind that i ran at a horrible track and the elevation here is like 3600 feet. I ran this with stock chip I didnt get into prom tuning until the track here was closed for the winter but i am sure it is running better know.

 

3600 ft. thats more than a second less corrected.

so low 13's would be my stab. I think you can dip into 12's easy. Have you port matched your upper plenum to the runners and the runners to the lower intake? That would help for some higher revs.

 

the only porting that i have done is the plenum (behind the tb and the runner entry ports)

 

Where do find out where your tracks elevation is? and what is the correction formula


thanks

 

Don't just port the runner entries. Portmatch them.
Also, portmatch the runner entries on the lower manifold.
The increased breathing results directly from the air not hitting anything because the portmatched entries will be nice and smooth. If you want 12.5 with LTR's then you'll achieve your goal much easier by making your TPI setup as free flowing as possible. Port that bitch like your life depended on it hehe.

Higher revs and more horses = improved times.

Those who don't agree are involved in the wrong hobby!
