Default GT45 Turbo on a CSS B18C5 block... Anyone want to gamble on how it'll do?

Gt45 turbo on our platform... I have a b18c5 css bottom end bored to a 81.5mm, eagle rods, wiseco pistons 10.5:1 comp ratio, type r cams, 1200cc injectors, 4piston ported skunk2 ultra race intake manifold, cast iron exhaust manifold

Will it lag a ton? Yes I know

But has someone used it before? My plans is to well just have it for fun for me. To help spool times, ditch the intercooler and run water/meth and fit some nicely sized intake piping. Has anyone ventured into that territory yet?

I'd advise against the turbocharger selection, exhaust manifold selection, and "no intercooler" choices made here. It's all basically a "pump", and each piece in that pumping system needs to compliment the other. A GT45 would be less than ideal in most cases (even when using a long runner tubular manifold)...a GT45 paired to a cast log manifold would be awful.

This wont be fun at all. It will be a complete waste of time and resources. Also the turbo will make more power on the lowest boost you could set it at and your injectors would be running out already.

Ditch the GT45 and get a GT(x)3x (whatever flavor floats your boat...GT(x)30, GT(x)35, GT37 so you can get more usable power under the curve. The GT45 would suck on a B18C dyno-queen.

Nothing wrong with running a BIG turbo depending on what you're doing with it. Drag racing it would be no big deal because you will be spending most of the time in the high RPM range anyway.

Now that turbo says it's good for 800 plus, well you could get 800 plus with a much smaller turbo, I've seen a 6266 make over 1000whp on the dyno. Now like others have said you don't have the needed parts to utilize the power anyways, 1200cc injectors are going to get you maybe 600 but I mean it's your car, do what you want.

it'll be short "fun". many of the teams I've worked with that was in pro mod had to make that switch to meth with no intercooler, all with disastrous results, to the point that the rules changed to go back to intercoolers. It didn't help spool times at all. do nitrous for that

please don't do this.. but. in the end, it's your car.

meth injection or methanol? Methanol has higher exhaust energy over e85 and gasoline based fuels.. i saw boostin perf go from e98 to methanol and spool a 6mm bigger turbo 250 rpm faster and 200ish more hp.. meth injection sounds like a disaster all to begin with... just run the right fuel and dont count on cheap pumps to be the life line of your motor.

Methanl Fuel being used in the Pro Mod class was a detriment to the chambers when it did not have a proper intercooler/aftercooler in the system.

Pro-mod class does not use methanol injection. Methanol injection is perfectly fine to use. Like with anything else, it's all in the setup. If you're not familiar with it, than it's all good, but it is not at all "Disastrous to begin with" , and would be considered a spread of mis-information. (What isn't nowadays with Reddit and other interweb op-eds when those that don't try, tell others)

I understand the use of Methanol, but it is NOT SAFE TO USE IN STOCK FUEL TANKS, and will corrode the inner lining of the stock tank faster than any E85.
