Thank you very much Paul. That is what I have now. The older style ls2 tb motor with a 102mm body. Seems like we all got the same result taking different paths.


Thank you too Thomas. Please keep us updated and quit painting you freaking car. It looked sweet back at Pony Wars!!

I wouldn't say its defective,a few have reached its limit once this was discovered Nick started working on a solution. It works for 99% of guys ,its actually in the cars pcm,we have had the old style close on us as well but the new tb works great with the new holley pcm ,so is it the tb or the pcm? GM is working on a program to adjust the sensitivity in the pcm

We tried Nick's TB this winter but it slammed shut at 6000 rpm on the dyno. Talked with Tom and Nick about it but couldn't get past the problem. Went to the LPE 102 TB and had success at the big end but the car wouldn't idle properly. Graham had a few goes but no luck so we took it off and sent it back for them to look at. Ended up with the ported 90mm back on. For now it doesn't matter my trans is on the way to Ted for rebuild and converter. One thing is for sure, the maggie has lots left in it if someone can get more air in than the 90mm allows, anyone thats tried will attest to that I'm sure.

It doesn't, you need a big head wind to push more air into the intake during your pass to get a quick time with a maggie. It's a known fact, I read it on the internet somewhere.

Mike, there is one whipple car having an issue with the throttle closing. It doesn't slam shut though. What it does it close the blade roughly 20%. It's not confirmed yet that is indeed the NW. They are searching other options as well. With the stock tb the whipple car was fine.

Ok. Stayed up all night and found some info. Some folks that have had this issue with the NW 102 have used LS1/LS2 TB harness adapters and reversed the wires so the butterfly opens the opposite direction. Seems to be a quick cheap fix but none of the cars/trucks using this fix were at our current power levels.

Switching the wires to the throttle motor will not help if the the motor isn't strong enough to keep the blade open under boost though

I'm happy with what Ted has developed to fix me up. It will be 100% turn key soon. He's just dialing in the cold startup air flow. Other than that it's perfect. And better yet, works at the track. Just bolt in on and go!!!
