Yep, and EASY to tune if you don't mind installing a wide-band and making a few tweaks............ whistling


Thumper can get a carb 'happening' for less than half the EFI money. When EFI gets close to carb prices and uses a dry manifold, I might just consider it.


Don't know what the EFI systems run $$ wise and don't care either way but do what you need to do AFTER you try the new and improved main body......... apimp

Thanks everyone... Thanks for your advise and suggestions.. !!

There are many aspects of the EFI that I like and would love to incorporate into my car... but at this time, I will take the wisdom of those that have told me not to convert over.. at this time..

I will give the carb another shot and see if I can get it to work to where I'm happy with it...

Thanks again for answering questions and giving your insight

Ok - follow your gut instinct ... but check out this dyno run of the pump gas Hemi that I had MM finish up for me back in the spring: https://youtu.be/95gZTspdzsg
It starts right up, idles real nice and learned it's own tune over several dyno pulls. That's a dual throttle body FAST EZ-EFI 1.0 up on top. 888 HP @ 6300 RPM ... I just need to find the other 12 ponies so I can say I have a 900 HP street engine!

Carb has worked fine when I'm there smile Just take that POS off and send it to me. Ill send you a Division winning one to replace it, was good enough to be in a ton of finals racing .90 should be good enough for you. Oh yeah loose the lexan scoop or start cleaning your air bleeds AT EVERY RACE!!! We live and race at places that are filled with dirt, it don't take much to clog a .029" hole...My guess is you already had someone try to make it better and they either lost the intermediate circuit or put a HUGE bleed in there. That aint the way to make it happy on the stop...

Oh yeah don't waste the time energy and money to go EFI, unless you just have to be different. If it was more consistent every bracket and class hitter in the country would run it. Also inline stops=crap for consistency especially for cars on the stop for a fair amount of time. Once again if it was the hot ticket Bogacki and every other racer in S/G, S/C and S/ST would have already done it.

But what do I know...

I have offered one up more than once....And if he was pout winning every round he would not be alone smile

Dom and INLINE stop and a baseplate stop are TWO completely different things. Re read what I wrote...

Oh yeah I have a pile of Wallys too, but how was that possible with three circuit junk, that Bogacki guy does ok with his too since we are gimmmeing us a break smile

Anytime and if you post your tune maybe we can help ya out but like Al said, a clogged bleed or any vital passage as small as they are can end your day and have you chasing your tail....... beer

Didn't realize Jeepmon was Don! It all makes sense now...The "lexan scoop" thing gave you away Don.
