When I say I don't like waiting for boost...
I had a 300 zx turbo. It took till 3500 and then bam, full boost. Nothing below 3500. I've rode in other cars that were turbo and I know boost onset is low, but full boost is not. Yeah you might make a pound of boost at 2K. But a good size turbo to support 300+ whp efficiently will have lag. Most miata guys running t3/t4's are waiting till 4-4.5K for full boost. It would be fast on a track, but I want power down low where normal people operate there vehicles in daily driving. I know this is HMT and I'm not bashing turbo's and all that ----. Just doing something different HMT style. Boost is better than no boost.

It's called a powerband, stay in it. Beyond that dropping boost between shifts shouldn't be a problem if you have a well designed manifold, which is what your fab effort should be going into.
Please update with "superchargers were the only thing that could make my miata even more gay, I'm going turbo."

Seriously what the ---- is their problem
Buy a tiny *** god damned turbo and run that ---- They're 8500rpm engines, factory. Bitch buy god damned clutch and stop launching at 4000rpm and shifting at 6000rpm.
Then they wie about lag... God damn it lag on an 8500rpm engine would be no boost till 4500.
Speaking of which... Unless you have an NC (which you dont!) you can't put more than 250 through the tranny to begin with so BUY A GO DAMNED TURBO TO MATCH IT.
Holla!

Re: Twin Supercharged Miata Build (56K Beware)
In short it seems some are lacking in reading comprehension and fundamental physics.
I never said I was running a SC to suck out exhaust and all that horse ----.
My car makes 140 flywheel HP stock. About 110 at the wheels.
As I said:
That's what I meant. I don't ease around trying to maximize gas mileage all the time.
I said the SC can make up to 28 PSI, but it's pretty efficient to 22 PSI. I didn't say I would boost to 28 PSI and achieve 300whp. This is a reading comprehension issue.
You bet. Care to elaborate? What's a SS engine? Wasn't wanting a oversized turbo. Your post makes no sense to me.
I don't want a small turbo, or any turbo. Never said I did. BP series engines don't turn 8500 my friend. The cylinder head does not suport high RPM flow. The engine is already undersquare. Oil pump gears break from harmonics and crank flex at high RPMs. Torque loading and shock loads are what break the driveline, not raw HP numbers. But I agree many people suggest 250whp is the upper limit of "safe" with some mechanical empathy. This topic is clearly debatable though.
Anyways if someone would like to put together a valid argument I'm happy to hear it.

Bitch quit rolling bullshit tiny ss engines with oversized turbo's. Get some mother ------- displacement dumbshit.
