any engine and turbos don't mix as well as any engine and a supercharger

I see many more blown up and failed turbo setups vs. supercharged. I guess it's because I focus on the PD stuff and don't really like Kenne Bell.

What you said makes no sense. I blew my first motor up while running a Saleen SC, and pushed the motor way too hard and melt a piston with the turbo due to a bad injector. IMO if you are really seeing more turbo charged motors blowing it is due to bad tunes, it has nothing to do with the turbo, if anything a turbo puts less stress on the motor than a supercharger due to no belt drag which wears out components and cause power lose, it take less boost with a turbo to make the same hp as a blower, or at least that is what I have seen and expired first hand.

I guess you're right, I forgot all of the shitty blower kits out there. Edelbrock, Saleen, etc...

yeah, because the only good blower is a vortech or procharger, btw had an FR1 also, it last about a month on the car, the thing performed horribly, made more power with the turbo on 3 less pounds of boost.

I've seen both turbo and supercharged engines go sideways. It usually comes down to either tune, user error, or poor build quality. My car is being put back together now. Just hoping he doesn't take forever as I have already been buried in builf costs with this on too of 8k in storage fees for leaving the car at his shop for just over 2 years now.

I looked at the Pro charger years ago, and could not fathom why their open cone filter CAI was located way up by the firewall, in the corner, on driver's side. Seems like the worse possible location, sucking in a ton of 200++ deg F under hood eng bay heat. Got into an argument with their engineers..and dumped them from my list.

How about the Roush Chargers? I have seen lots of negative stuff on here about the Roush SC's, but I've yet to see anyone talk about one of them blowing up their motors? I'm sure it's happened, but I see way less bad talk about the Roush Chargers on forums than I do all the Turbo's and other SC's.
I've got almost 60,000 miles on my M90 pushing almost 9lbs boost (since 30,000) and have never had an issue with it or my motor, and I push my car hard doing track days and 1/4 mile....
I also have never had an oil catch can that everyone claims they need on these, primarily because I could not find anyone who made one for the 2010. I have never fouled my plugs or plugged injectors....
The only complaint I have on them, and any SC for that matter, is the amount of heat they generate. You need to have adequate cooling.
I also have to say when I stomp on the gas(so to speak I drive with hand controls) and feel/hear the whine of that SC kick in, I'm not thinking at all about how much power the belt is sucking out of my motor.....

I agree on that last part you said about not thinking about how much power the belt is sucking out. I never really thought about it much in the past but it makes me think back and wonder what's left on the table for power.

Also does anyone know what the hp limit on 93 octane pump gas would be. I spoke with Lito and he said he wouldnt try pushing over 700hp on 93 octane which would basically make upgrading my head unit pointless.

Lemme get this straight. Your oem 2010 3v, 281 ci blew up....and is being replaced with a B326 stroker ?
326 = 5.3442 L. With 93 octane, dual GT-500 pumps, dual bap, bigger injector's, LT's, etc, etc, I'm guessing 700 rwhp is the max you can expect to achieve. Which is overkill for street use, and hardly justifiable for 1-2 trips to the strip each year.... but that's just me.

To make a long story short. I pulled the original motor and sold it and purchased a stage 3 b326 motor from brenspeed. A shop in my area took my car in for an inspection sticker and blew my new motor. Now it's being rebuilt. With my setup I had before it blew it dynoed 642rwhp which I enjoyed and did not find overwhelming yet was there when I wanted it. If e85 was available in my area I would go that route but I am stuck with what's available to me.

I don't have good input on the 93 octane, we only have 91 here is stupidfornia, that my little stock 281 3v could compare to what you are running now, I only made 489rwhp at 10psi, but the car was a blast to drive on the street. I would probably go with what Lito has to say, better to be safe than sorry.

Agreed I can't pay for a new motor a third time unless I like divorce.

I have my car tuned for 600rwhp. I think this is the max that is still enjoyable on the street and even this requires street radials to hook at all. I don't really understand the guys that want to run 700-800rwhp on the street, it gets really squirrely at those levels and to me anyway, it isn't any fun anymore.

For me it's because of where all the horsepower falls into a centri blowers rpm range. It really doesn't start building boost until around 3500rpm so it keeps it pretty mild until you get on it.

That's the issue with any centrifugal blower. The boost increases to the square of the eng rpm. IE: 10 psi @ 6 krpm. 2.5 psi @ 3 krpm. .625 psi @ 1.5 krpm. With any positive displacement blower, the boost curve is essentially flat, typ a tiny bit lower between idle + 2 krpm. You get the big tq hit with a PD blower. With a centri, you have to be dropping down some gears to get the boost, and even then, you don't get max boost, unless you have max rpm. IMO, a centri is like buying 1/2 a supercharger. I mash the gas, I want the boost now, not next week.

For street use, a PD blower, with reasonable boost, is hard to beat, and very reliable.

Agreed, when my car had the little Saleen SC on it, it was a blast to drive on the street.

That's why actually like the centri because the power is on tap when I put my foot down but I don't lose traction in the lower rpm range. At the track it can really be unleashed though.

Eaton makes the good blowers, everyone knows that, and the correct setups are from Roush/FRPP/VMP.

Well I am definatley getting raked over the coals with my tuner. He is now putting together a new invoice because my car was sitting so long that his shop had to spend hours removing the wheels to unfreeze the brakes and to also expect a flat tax percentage for hazmat costs after I already paid 8k in storage fees alone. On the plus side he sent me a video or the motor in the car running so I'm at least close to the finish line I hope.....
