hey guys, i have been searching for a wile now and cant find any good info. Is it better to go with a big single (106-114) or twins (88-90)? i have seen this asked befor but no one really gave a reason why they picked one. I have been seeing some people switching from a single to twins and others from twin to single. sorry if this has been asked 1000 times already and thanks for the help.

single turbo. When you're going THAT big it means you're going for a race setup and you will most likely not care about how it spools daily driving, so think about it---would you rather spend the money on one set of parts thats gonna make 1000hp or would you rather waste the money twice on TWO sets of parts(two turbos, two wastegates, two sets of pipes, two blow off valves, etc etc) and STILL MAKE 1000hp? Oh and twice the weight added to the car since its TWICE the amount of parts generally speaking....its all relative but i say stop asking questions and go straight to single. It will easily get whatever job you want done well. good luck on the build btw

Thanks for your help. I was leaning tord single but now i really am. I was seeing a bunch of the faster cars (200+ in 1/4) using twins so i was unsure.

i would hope twin 88's or 90's like he mentioned would make more than 1000hp, lol

What size motor are you planning on running? HP goals? RPM range where you want your power? 1/4 mile times?

Answer those questions and then you'll be able to see what size(b) turbo(s) to go with.

I am hoping to be able to go high 6s or low 7s and it would be on a 500+ci motor.I think for those goals I would need over 2000 hp. How come the big dogs use twins?Is ther just not a turbo that is big enuff or is it no room for a big one?

How big is your wallet?

I would prefer a big single...just to keep it simple. I don't think it is a matter of cubic inches. There are plenty of big turbos out there that can get you where you want to be. Paging Dr. Turbo...paging Dr. Turbo.

alot of guys run the big single because of class rules or weight breaks given to the single-if you dont have any restrictions go with the twins,with the correct sized turbos you can make more power with twins than any single-but you can easily make 2000hp with a billet 106 or a 114
we put a billet 106 on Phil's car and it easily makes 2000 hp on a 438 lsx
i have twin 88's on my 436 sbc and make somewher above 2500 hp
if you have any questions i'll be glad to help out,just shoot me a pm or call the shop

Thanks for the help guys but im still a little confused why twins are better then a single. Do they spool better,make more power?

lol ok thank you ill go with twins

From what i understand (which is fairly limited mind your), twins are better because they allow you to run smaller turbos which are more efficient and spool faster.

On a side note, do you truly understand what it takes to get a car into the low 7s and 6s? Its a lot more than just rwhp. You are talking complete (custom) chasis work (call madman) for starters. Is your wallet bottomless? I may be completely wrong, and you may have built dozens of cars that run 7s, but If I am right low 9s would be a more realistic goal. I mean prostock cars run 6.70s. Are you looking to build a prostock car?
