I think twin 91mm on a 440 with a 100 shot would be a fun street car.



I just had to lol!!

Def won't be doing twin 91mm anytime soon. That's alot of $$$$$. I'm def leaning towards a 91mm dbb of some sort?

Yes awd will be interesting. Right now the truck has 4 drag radials 285 in the front and 315 on the back. Just got a set of ccw classics and will be putting Mickey Thompson on it with 335 in the back and 295 or 285 on the front.

Exactly. There are a ton of different ways to skin an LSx.

Once you get it all together and running, you're just getting started. Ultimately, with the correct controllers, electronics, converter, gearing and strategies, either can work equally well.

The mistake that I see most often is when people slap it all together, it doesn't doo what they thought and they just start swapping **** around without working out the issues one at a time. That or they get frustrated and just sell the car.

The guy who is fabricating the kit with Modular turbo has an AWD s10 that he built himself with twin turbos. I have watch my fair share of races that the s10 should have lost but it pulls so hard out the hole that some drag cars cant beat it to the tree.

i can get the 427 for the same price as a 370 trust me. so that being the case hopefully a 91+ a 427 will make over 800-900hp to the ground. Yeah the awd should fun and making it hook will take a little time.

Well sell me a few of them! Because a lsx 427 is about $3000 more expensive then a stock crank 370. Thats just before you get to the $$ difference in heads.

You will be able to make that with ease on pump gas with a decent set of heads. I would do twin for a fun street vehicle but also the 427 will make plenty of power to get out of it own way out of boost so a single will also get it done. There is no right or wrong setup as long as the turbos are sized correctly.
