(Another) GPI Max Package teaser - this one with traction!
Hey all. We're sooo close to having the new Max Package live with all of the details, pricing, etc - but I couldn't resist sharing one more teaser with ya'll.
I finally got a little tire under the car and can (mostly) hook 1st and 2nd gear now, so we can really see how this thing digs. Obviously, with a burnout, some prep, and 10-12psi less air pressure, this will do a lot better in those first 60', but it's flying pretty good once it gets rolling.

Yea, that's exactly how it is - fun. It's never going to compete with weight reduced automatic cars, or anything with forced induction, but for an all motor, full weight, stick car, it's very stout and holds its own pretty well.

LOL - the whine is what you get with an aluminum case differential with 4.11 gears, a diff cover with load bolts right on the main caps, and then hard poly bushings in the diff and solid aluminum bushings in the rear cradle. It's like a stethoscope right on the gears up into the interior of the car. It sounds very cool and race-car like when you're playing around, but mostly it's just super annoying!

Man, the m10 6060 has such a wide ratio on that 3-4, reminds me of the D4 mt82 on the mustang. A 1le spec 6060, with the longer 1st and closer ratios, in the works? If that one needs gone through…why not?

Eventually, I'm gonna try to source a MM6 in really nice shape, which will be about like an M10 with 4.10s on 1-2-3, but then have a much better 4th, and again keep 5-6 about the same. I think it's going to be awesome, it shouldn't hurt it much down low, and the MM6 3-4 is an such a nice ratio, and in the right spot too.

Damn that car sounds nasty. Sounds like you're revving pretty high!
I can't wait to hear more details on this, I've been planning a high revving LS3 build to drop into a C5 Corvette, aftermarket LS3 heads, Fast 102 with the mid length runners pretty big cam (probably Cam Motion LLSR) etc. Seems like you may be putting together pretty much exactly what I want. |

When you get it all squared away Andrew, are you gonna be able to beat Ryan's Camaro?? Or just come close. I've seen the vid of his Camaro, WOW...

I've got a valve-train setup that should be very solid and well controlled out to 8000rpm+ as a little buffer for over-revs and all the stupid stuff that happens when the TCM doesn't get the shifts right. In this case, the TCM in this car is the computer between my ears as this is stick shift, it can be very unreliable. The valvetrain is Johnson ST2116LSR link bar short travel lifters, Comp XD-A adjustable length push-rods, Comp BSR Max Lift shaft rockers, and PSI 1513 valve springs. It might be approaching overkill, I have a soft limiter come on at 7700rpm, and the hard limiter is 7800rpm. But on the other hand, if you miss a gear and give this a determined throttle stab you're NOT stopping at the limiter, the acceleration and inertia is going to take you easily to 8000-8200 depending on how quick you get out of it. Without giving away all the upcoming release details, let me tell you a bit about the "Max Package 2.0". Years ago we used to offer an LS7 heads/intake and cam setup for LS3/L99 cars. It worked very well, and would make a little more power than a good LS3 heads/cam car. But it had some compromises about it that we weren't totally satisfied with. So, we redesigned it. The new version, we're calling it Max 2.0, uses a Brodix BR7 casting (aftermarket LS7 head) which we do our own finish work on to set the port size/profile, and valve sizes to what we think is about perfect for the bore size of an LS3. It's a 12* valve angle, which helps us run both more camshaft and less combustion chamber (more compression) than you can with a stock bottom end and LS3 heads. 1.8 LS7 style rockers, LS7 ports, all the goodness of that head design but for the bore of an LS3. It pairs with a few different LS7 intake manifolds, we have the LSXR on my car, but a hi-ram is always an option, and an MSD Atomic can be made to fit with a little clearance on the manifold. 103mm TB is the way to go with any of those manifolds. Using the LSXR intake and simply bolting it on should make about 10% more power than a SS4 NFC/ported LS3 heads/stock intake car. Flycutting to add some more compression and then running a hi-ram can take power levels up substantial more. It's more costly that a cam and set of ported stock heads and intake, as any time you get right out on the edge of truly max effort stuff and diminishing returns, you're paying more for those last bits of performance. For the guys looking for max effort NA stuff in a true bolt on package without touching the bottom end, it's a killer option.

So, I don't have plans to do the weight reduction, auto trans stuff, drag brakes, wheels, etc that it takes to be truly fast. This car, as it sits at 4,100lbs today, probably is still gonna be tough to wrangle a 10 second pass out of, even with all this power. If we dropped this powerplant into a committed drag car with a TH400 and a sub 3500lbs race weight, it would go mid-low 10s on the first lick down the track and have a shot at work it's way down into that 9.99 territory.
