I have been told to do a 4" stroke for a supercharged motor for my 99Transam . Who here has used a small CI motor and what was your results and combo ? I have a Novi 2200 supercharger just don't know what CI size to go with . Do I go with 408 and do 12-14 psi or go smaller CI and max the blower out ? My car is a 6speed if that helps

What power goal are you trying to hit? That would help a lot more than psi. For a 2200 I would go with something between a 376-416 with compression in the 9.8-10.2 range.

Looken for 750-850 hopefully lol ��

That's easy for a 2200.

Yea, but what CI

I have a friend that is trying to get me to do a 2jz, or a rb26 in my transam . I wanted to be different, so I went with Novi 2200 instead of a procharger . I just lmao �� when he talk this **** ��, but they do make some damn good power .

I did 975ish on a 346 with an F1R worked great. If you want to stay on 93 octane shoot a little lower on the CR like 9-9.5 it will leave you some saftey and not leave hardly anything on the table. GL! And budget determinds your motor really any of them will work the bigger the CI the more TQ and the HP will be simular so the bigger CI will feel faster, but because of traction it might be slower on the street anyways, so just depends on your car and budget GL!

Boost is basically a replacement for displacement. There are 3 liter engines making 3000 hp. Don't over think it. Stock displacement 5.3s have made 1400 with an F1X procharger.

If you want to replace the crank, it wouldn't hurt to get a stroker crank for the same price. You can start with a 6.0 block a buy a balance rotating assembly and be done with it.

Just do a 376 and shoot for the compression where I stated. Won't need to run a lot of timing on pump to make power.

with a 6 speed and that blower, your goal wont be a problem whatever size motor you choose.

Im building a stock bottom end 6.0 with a ysi(same blower as novi 2200) and think it will make than much power through a th400.

rkreigh

blower flow will compensate for lack of cubes and as long as the engine can tolerate all the cylinder pressure, make all you can

the small bore blocks see to be more detonation resistant

but for 800 or less, I would try out a 370-383 as suggested

I'm going to try an LS6 stock 3.86 bore with a 4.0 stroke (got a better deal on the stroker) with studds and forged lunati crank, rods, and pistons in a 4.8 iron block

this is boring the block more than I would like, but I got a killer deal on this rotating assembly and want to go for it

good luck on your build, don't skimp on the fuel system or injectors

It more boils down to your driving style. Any motor can make the power.

If you want more torque, more low rpm grunt, then go with the larger motor.

But you wont need extra capacity to make the headline numbers.

Agree with what is already posted. Honestly you could hit your power goals even with something as small as the 4.8 or the 5.3. If it were me, I'd aim for the 376 though and somewhere in the 9.0-9.5 CR. It would allow you to easily hit your power goals safely, but it also gives you room to grow if you wanted to down the road.

Plan on running methanol injection? Also what fuel do you plan on running?

I planed on meth , and 93 . But never planed on tuning for meth . Meth was gona be just to help on hot days here in FL .

If your tuner is experienced with it there is no reason not to tune for it. There are failsafe's they can use in the tune.

Yea, just don't want to have to depend on it all the time . How long would a 2.5 gallon last . Any bigger would be a bitch to find a place for . Thinking I may go with a 408 or 376 on 16-18 psi .

Detoxx03

Would last a long time unless your driving around everywhere in boost cause that's the only time it sprays lol. Mine is 1.7 gallons and I'm running two big nozzles and don't have to fill it often.

Don't worry about psi. Shoot for a power a goal and it will make what it makes psi wise. If it makes your goal on 14psi would you be disappointed? No of course not.

Lol �� good point . I would be happy with 650-750 at the wheel . Anything after that is just wasteful. Over 750 hp would just haze damn tires on hard accreditation. Traction would be a problem . I might use a wastgate and limit boost for daily driving .

Edited my last post to include how big my tank is.

Thats eash for that headunit to handle. Could always just use a restrictor plate instead of having to but a waste gate and controller.
