Hi guys,

I was excited to test out my new setup last night at the track only to be shocked by getting 13.4 on 10psi and 13.3 on 13.5 psi!! I ran an 11.7 on my last setup with a 2.3 whipple and meth.

List of current mods:

Stock 3.42 gears

Bullseye Power 94mm BatMoWheel turbo with 1.50 A/R

4 downpipe into 3.5 inch muffler and cat

ID1300 injectors

PRC Stage 1 LS6 Heads

Custom Cam

6.3 forged stroker (383ci)

What do you think the problem could be? Is it the stock converter and 3.42 gears? or is it something else?

Any input will be really appreciated to get this pig moving.

Thanks

 

The turbo is about 20 mm too big. What was the 60' and 1/4 mph? That will help out more

 

On the 13.4 run

60ft: 2.357

MPH: 111.6

On the 13.3 run

60ft: 2.509

MPH: 114.69

 

Is this a single cab truck? The 60' needs some SERIOUS work. Get a converter to match your set up. The mph is the same as mine and I run 11.8 but with a 1.7 60'
All I have is a simple 6.0 with a small shot. I'm thinking it may be tune related only going 114 with your set up

 

Yes, it's a single cab. Was thinking of getting Circle D's multidisk 3000 stall converter. Would that suffice? What about 4.10 gears? I will look into the tune as well to make sure everything checks out.

 

Lets start off with whose turbo kit? You stated 4" manifold which has to be a typo

 

So you have a custom can and a stick convertor?
Like George ask who's turbo kit need some info there.
Oversized AR? What size AR? What size exhaust wheel?
Who's turbo?
Looks to be a few mismatched parts here.

 

OH man. I hope you can get this figured out. I'd be pretty upset too

 

You have to realize the first 60 feet is the most important part of the 1/8 & 1/4 mile ET. You can get a pretty good idea how much power you're making by the trap speed.

 

It's a custom kit with all piping custom fabbed locally. Sorry for the typo, I meant the downpipe was 4". The turbo is a Bullseye power 94mm. I'm also running a Turbonetics Godzilla BOV and a TurboSmart 60mm Wastegate.
