ok I found kenne bell supercharger systems...intercooled are 4999.00 and non intercooled are 3899.00 that sound right? and would it be cheaper to get a different intercooler from somwhere else? or is the intercooler needed at all?

[thewayshemoves]

or actually...what about a turbo setup? but would I get the same low end torque that apparently a supercharger can give me? I'm asking these questions because this spring I'm getting a large sum of money, and thats one thing I'm looking to do is forced induction...I'm on stock internals..so what's best for low end torque? 1/8 mile drag racing, type thigns?

[gills99stang]

You're probably best off with the s/c... just don't run too much psi on that stock engine.

[matrixpuba]

if you do the KB setup get the 9psi intercooled kit. skip the 6psi kit

[thewayshemoves]

what is a safe maximum PSI that stock internals can take? And what about twin turbo?

[gills99stang]

I think it's debatable, but 10 psi with a Procharger P-1SC is pretty safe.

[matrixpuba]

if you keep the block around 400-420 on a good tune you will be safe. if you can spend the extra money, do the TT setup

[thewayshemoves]

I was leaning more toward the TT setup, once I read some more about it, the only problem is that I don't know exactly why? lol...can I get more from the turbo?

[gills99stang]

I was always under the impression it's better to go with one big turbo vice a twin setup... but then again I don't know much about turbos.

[thewayshemoves]

me either really...wouldn't that be almost the same concept as two throttle bodies though? like you can get two throttle bodies, but you'de have more diameter out of one larger one? is that kind of the same concept? you can get more air in through one large turbo than two smaller ones? or am I completely off?

[stangc83]

the cheapest i have found with the intercooled is about 5000. the twin turbo option costs about 7000 and it brings you to about the same. And 10 psi should be a good psi max. After that you will have to forge everything. it will bring you to like 450-475 at the wheels

[itschristorres8]

you can get alot more from a turbo, if you have the money twin turbo it FOR SURE. at the same psi you'll beat the s/c

s/c GT 10psi vs TT GT 10psi
TT GT will win it every time with as long as all mods are the same except one having a s/c the other having twin turbo

[thewayshemoves]

thank yall, I found a twin turbo kit, thats intercoole for 5389, which is only about a hundred or more so than the single turbo kit, and the turbos are greddy, so I don't think thats too bad a deal. Me and my friend put a turbo on his 240, so I don't think it'll be too much extra trouble to put a twin turbo on the GT, its mostly common sense and plumbing. Plus it comes with a chip to tune for it and 48# injectors...I don't think its a bad deal...I'm getting money from my grandmothers life insurance, and thats what I want to do with it, it'll be this sumemr though

[thewayshemoves]

so which is better though, and why? twin or single turbo?

[FOR POINT SIX]

Just be careful if the price is cheep there is a reason for it. You get what you pay for.

[itschristorres8]

single vs twin.....
really depends on the turbo size

twins will spools quicker then a single but there are single turbos that spool instantly...

but my vote is twin turbo


but that doesnt mean single sucks at all.

smaller impellers spin easier so they spool up quick,but bigger impellers create more boost once they get going. so i think it kinda evens out.

i read that rear mounting turbos add 50hp due to less heat,not being cramped up in the engine compartment but you may lose 1lb of boost because they're farther away from the intake.

fair trade IMO.

but the thing about s/c's is they take away hp since they're running off engine pwr but they give you "out-of-the-hole" lowend.

[Invictus]

no.. you don't have dual throttle bodies with 2 turbos thats not the concept at all. twin turbo setup vs. single turbo setup is just to reduce turbo lag. at lower rpms all of your exhaust flow will be directed at your primary turbo,the second turbo is also prespooled so that it will kick in immediatley when you get to a certain boost level or engine speed. at that point you'll be experiencing twin turbo!! the valves will be copmletely open on both blowers this is how my friends 99 supra TT is setup.

on our modular engines ( v8 series) we put a turbo on each bank and they spool up at the same time, this makes the installation a lot eaiser and less complex. each blower is on its own exhaust manifold.

the turbos wont make as much low end as your KB 9psi setup obviously becasue they have to spool up but if you're willing to sacrafice some top end you can tune them to spool up much earlier but less boost ouput its a compromise

and yes you def. want intercooler.

fair trade indeed +1

the kenne bell 9psi will give you better low end becasue there is no lag at all. (without question ur best 1/8 track mod) the impeller is drivin by a pulley which is powered by your engine so there's no lag at all.. thats the only benefit to a supercharger. the downside to that is, it robs a portion of your engine power (that could otherwise be put the wheels) to power it. so theres a parasitic loss.

the turbo kit is powered by your exhaust (an ingenuis idea because it's like recycled energy).. and at low rpms your engine isnt producing that much exhaust so the impeller in the blower isnt spooling up fast enough yet to produce a considerable amount of forced air. however becasue there is no parasitic loss the turbo kit will produce more power at the same boost as a s/c kit


it comes down to ur own choice tho! the kb kit will cheaper, eaiser to maintain and tune and give you an amazing amount of low end so i'd invest in some tires.. and the turbo will give you much more mid-high end and i think they're cooler personally lol. like wavebye said, its a fair trade
