Better Supercharger

other than moding the m90, I know there are better superchargers out there, which one would you guys buy, and why?

Well theres the ever popular Gen V m90 off of the gtps , worth about 20hp and can usually be found for 6-700. people who have them seem to really love them. And they sounds better too.

Then theres the MP112 , which can be adapted for use on a 3800 , looks/sounds awesome but isn't too much more efficient than the m90 , so most shy away from it. Idk about costs either but it requires a lot of custom work i'd think.


And then we have the whipple , sounds great , can make incredible amounts of power over the m90 but is costly at around 3k for the kit , which is off the market too btw , but should be returning soon enough.

Then there is the CSC option , theyre very effiecent , but don't deliver the low end torque of a roots or twin screw positive displacement blower.And they don't sound that good.Plus i think it would have to be entirely custom.

And then there is the turbo option. Lots of money , but lots of power , they say to expect about 400hp with just basic mods when going turbo. They make the exhaust note sound pretty cool and you can get better gas mileage in theory. Most people who want very big power go the turbo route.

Those are all the main options

I was going to say TURBO! Best type of supercharger for racing. I think the M90 is better for street use. Torque is your friend for daily driving.

definatly only street driving but i feel that i need more significant gains, than the m90, so whipple sounds bad ass, how hard is the install??

is there a certain model to buy or should i just google it and check for a kit?

You can do a lot with an M90 for less than a Whipple costs. Look at ewolfe, making well over 400 HP.

I did man his car is just awesome, id like to get my ride up to that level by mid year 2009, i will look deeped into the m90 mods, ill keep checking ZZP, and INTENSE, to find the best stuff, i have alot of work ahead of me though and id like to plan out the most efficient set-up up for street driving and occasional runs at the track,.....maybe.

Just remember the big supporting mods need to be in place regardless of the power adder used. ie Transmission, bottem end, top end, tuning. Still fresh in my mind, is a customer I spoke with a few days ago with a gtp telling me that you don't need an upgraded bottem end or breathing mods and stuff like that to make over 500hp using a turbo "because they are more efficient and don't strain the block and pistons as much."

I'm sure you are well aware that with the amount of work you look to have in store, your biggest costs will not likely be the power adder. Everyone that has done what I'd call a lot of work to make power have spent well into 5 digits on the drivetrain. The power adder is but one part of the equation.

Just focusing on the power adder, the genV is a tried and true and highly supported path to about 400hp to the wheels. You can always giggle juice another 100 is you feel foxy. That's quite a bit. Doubling stock power while maintaining full street drivability is impressive. If that's not enough and you are willing to make some small compromises as well as take the path much less traveled, the all mighty turbo can take you as far as you want. The MP112 is dead and the CSC is just a supercharger that really should just loose the training wheels and be a turbo for the amount of work it requires.

i was thinking , cam, lifters, rocker arms, push rods, FWI, exhaust, intercooler, MAFS, boost guage, oil pressure, and tranny temp, good tires, PCM tuning hoping this is the best way to go

by the way turtle where did you get the bulbs for your door handles?

If you want to do all that stuff, you'll be wanting to do an HD transmission first...

If you are doing all the mods at once that list is a fine list, maybe sans ported/larger TB. If you are going to tackle them in order put the exhaust first.

P.S. Please add the year of your car and any current mods to your sig so we can help you better.

And you don't want to do both a cam AND high ratio rockers... one or the other. For what it sounds like you want, go with a cam.

BTW, are you planning on doing all the labor yourself?

You can do a cam _and_ rocker upgrade, in fact it's often recommended because you want a roller rocker for the higher RPMs a cam will allow. You shouldn't increase the ratio unless your cam isn't enough, then you just want to go up to a 1.7, otherwise you have clearance issues, depending on your cam.

wheres the best place to go to get tranny work done, and what do i need to have done to it?

From Buffalo NY? I'm not sure. I would go to a local builder (check w/ your local area GP club) who has done a few. Get the hardened input shaft and pump shaft, and in my opinion the gear set with hardened gear and 7/8 single hardened chain and you won't have any problems. If you are going for 400 hp you'll want to talk parts (or the whole thing) from zzp or Intense. Seems like people have a lot of issues with Intense's transmissions, but it also seems like a lot of those issues are caused by their LSDs. A typical HD transmission build is $3000 or less.

Yes, I was referring to the more common higher ratio rocker swap. I see more guys choosing 1.8 or 1.9 rockers, or just going with a cam upgrade.

I wish there were some GP, clubs here!

its alot less work, installing rockers than a cam, probably the same price range though, i have a better success rate with the rockers, and all the tools to do it, but then i have to have PCM tuning done right? and if i wanted to up grade to the Gen V, what would i need , i.e.) manifold TB, Ive also been realy considering a pulley swap, i want to go down to 3.4 i saw a list somewhere in this forum that stated what upgrades i would need to compliment such a change but i cant seem to find it again.

what do i need to install a gen V? on my l67?

You have to modify your LIM or get one from the GenV Donor car, it's not that hard to modify, I did it with a cutoff wheel and sawzall for one car. I think the belt length may change, I can't recall exactly. The one I put in was also getting an IC, so the belt length definitely changed on that one.

For TUNING help in your area, go to Gary at www.hollandmotorsports.com

Ill call him and see. Thanks

IIRC, I don't think he is doing tuning anymore. I would still contact him, but I am pretty sure he is getting out of the tuning business.

That sucks but im sure i can get it done somewhere around here, Theres a hole in the wall drag shop over here that helps all the ricers in there Homo-mobiles go what they assume is fast, im sure they can help or point me in the right direction.

For the door handles maybe Ed Morad has some but what I do is remove the pigtails from the door panels, pop the blue lens off, remove te burned bulb and solder in a Grain-of-Wheat bulb, then pop the blue lens back on. Because the pigtails are now made of Unobtainium.

You may need to shave the back of your alternator. I did and think one or two others did. Belt size should stay the same unless you change pulley size or intercool. Other things that change are your TB either needs to be adapted or you need to change the TB, maf and intake.

Beyond that..it bolts up nice. Make sure you get the longer bolts required for it.
