Exclamation New to Lt1

Do they make a root supercharger for the LT1? i found a good deal on a 95 z28 m6 for 5 grand decent 70k on her and she has 4.10 gears, drag radials, full exhaust, and cai, wut can i expect out of her at the track thanks!!!

Re: New to Lt1

The car should run in the low 13s to 13 flat assuming a good launch and shifting and that its a healthy motor. m6 cars are really tricky to launch though.

No roots available, lots of centrifugal.

Re: New to Lt1

Depends what your "full exhaust" consists of. I'd be more inclined to say closer to the mid 13's than to 13.0. Long tubes, if it doesn't already have them, and a cam. There's a few small items that will help you like 1.6X roller rockers, throttle body bypass, 160deg t'stat with a good mail-order tune, etc.

You may want to take a look at this. It's long, but it's worth reading and seeing the pictures.

Keith at MPE is known nationwide for the fastest FI LT1s/turbo GN. He is doing all custom work and can set up a killer Eaton or any other Roots type or centrifugal supercharger or turbo for any application. How about a fully streetable 800 RWHP? He can do the same for F-body.

Also you can check this thread. Some good info on page 2 and another source for Roots blower kit for f-bodies:

2.3 and 2.4L twin screws are very efficient from what i've seen.... all the stats i've seen on them have volumetric efficiencies of about 92% and adiabatic efficiencies of about 70%, all while moving approx 1000cfm (1005cfm is advertized for the 2.4Ls, whipple has the 2.3s at about 980cfm IIRC). They must be good since many of the KB cobras can run upwards of 18-19psi on 93 pump gas without detonation on stock engines (~600rwhp).

If the whipple 3.3L has about the same efficiency ratings at the 2.3 and 2.4, that will be one hell of a blower.

Re: New to Lt1

If youre going to go through all the trouble of getting a custom top mount blower you might as well shoot for the Whipple 3.3. I cant speak for how well the LTx or LSx will perform with it but Ive seen how they perform on Lightnings and Mustangs to know it's not worth it IMHO to go through all that trouble for a Eaton. mabey a ported eaton or Magnum though, mabey depending on what your plans are. Kenne bell would be a nice blower to go with but I still dont trust them due to thier blowers locking up or has in the past. Either way When ever Lysohlm or who ever it is starts back sending rotors a whipple will be in my near future.

Re: New to Lt1

I ran 13.62 with just catback, DRs, and CAI through a M6. That was with a 2.1 60ft. A better 60 and I should be at 13.4 or so. With full exhaust I can see low 13's maybe even 13.0.

Go all motor. You can easily run 12s all motor on an LT1. It would be cheaper than a turbo/supercharger.

I'm sure it'd be high 12's with you driving... you're like a freak.

MPE website: http://mperacingfab.com unfortunately it's been down for a while. I asked Keith when he will fix his website, but the man is really busy with all his customers setting up the twin turbo setups.
Email is: mperacingfab@yahoo.com

Phone is: 1-856-678-2638

Info for Twin turbo setups can be seen in the Impala SS Forums Forced induction section: http://impalassforum.com/noncgi/ulti...ubb=forum;f=15, Or call/Email direct for more information. You can call Keith, he is very friendly and nice to talk guy. I just sent him email regarding his Eaton blower kit and wait for the answer. His custom sheetmetal intake base and air intake is state of the art as can be seen on the pictures I posted earlier today. The guy is really talented. There is an Impala SS (2 tons car!) running 9s in quarter with his turbo setup.

According to Keith at MPE, Advantage of going with Eaton is RELIABILITY. They are proven in production vehicles like Lighning, Cobra, blown 3800s to be trouble free for at least 100k miles. No bearing failures, no leaks, no rebuilds. Advantage: instant boost off-idle. Bolted on a stock high-mile LT1 showed 180 lb/ft of torque gains. With a good set of heads, exhaust and one of Keith's custom camshafts, you get fully streetable 500-550RWHP, but at this point Keith said "you better have a stout forged bottom end and bulletproof drivetrain, because if not there will be a parts breakage". This is with EATON blower and about 10-11 PSI of boost. The beauty with EATON is streetability. The MPE cam is in 22x duration without excessive lift, almost smooth idle, tons of torque from idle-up, you don't have to rev them to the moon to go fast, yet you can run with big cammed strokers that make no torque below 3000 RPM and must rev to 6500+ to get their full potential. Then there is that under-hood appeal at the car-show that will attract crowds.
He said, beyond that one would need a bigger blower like one of these Honda Hunter mentionned and with bigger blower you're looking at about 800hp if you use all the parts he suggest.

Check the links for the Roots type blower I posted on my previous post this morning. Did you see the pictures. It's the Roots blower on LT1.

Reliable until you start raising the boost. Then the intake temps become a issue. Porting the eaton will yield more power and are on par with the Magnum Eatons or as they say Heatons. But either way Ive never seen one on a pushrod. Ive only seen them on sohc and dohc 4.6 and 5.4's. Completly diffent worlds.
