Hey Everyone,

I've been tossing an idea back and forth with John, Alpine owner. He's got upwards of 30 older generation M62 Superchargers laying around. So I thought why not put one of these bad boys on the I4 Supercharger Manifold and sell a higher boost race only kit. Combined with a Unichip the M62 shoud be able to slap down some serious power.
The reason it would be race only is because the older M62 supercharger does not have an internal bypass valve like the newer MP series. What this means is that even while your sitting there idling or cruising the supercharger will be generating boost. Which means fuel economy will suffer at the expense of more power.
We're thinking about going two routes with this setup. One would offer upgrades to existing supercharger kit owners that are looking for at least 200whp out of their setup. Another would be to offer complete turn-key kits.

What do you al think? Is there enough interest for John and I to pursue this endeavor? If there is enough interest would anyone be willing to put some sort of deposit down on them right away?

 

I do believe youd have to make it suitable for driving to attract people to be interested in this, is there no way to modify it so it doesnt make boost when cruising?

If you could do that im sure people would love a supercharger that could make a good amount of power.

 

I don't think too many people use their Tiburons for race only, for the majority of us we were are daily driving them or they are our only car.

I guess the question would be how much of a hit to gas mileage would it make... and how much strain would it put on the transmission and car as a whole at idle. I've seen supercharged cars not even be able to move without jerking forward when moving from a stop because of the supercharger making boost at idle.

I myself am definately (as in 99.9%) buying a supercharger kit in the spring if it can make 200~whp out of the box for a reasonable price. However I'm not doing that at the expense of horrendous gas mileage and jerking around town as it is my daily driver.

 

DmDicks, I'm still waiting for you to call me.

I can't even remember what about now, it's been like a month.

Anyways, there have been a bunch of questions in your sub forums about the new supercharger manifold design, the new pulleys, all sorts of stuff, I'd answer these questions first and see what we can do from there.

Oh, I remember, it's about me talking to Unichip when I was at the Nopi Nationals. That and the partnership stuff.

As for THIS project, I'm having a hard time understanding. In another thread you said it would be very easy to get 200 and more WHP out of the new supercharger setup with the new pulley and such, with 250 being very possible, but with this one we can expect right around 200 and big fuel problems?

Isn't there a way to setup the M62 so you can have the boost on cruise and such blown off?

 

Hey Redz,

I'm horrible at remembering to call people. Unfortunately I've been crazy busy at my full time job and haven't been able to help Alpine much lately. Hopefully that will change soon. I get like 5 min a day to go through all 15 forums I'm a member of. It would be nice if people could post all the questions they might have in this forum so I can go to one place during those 5 min.
To answer some of your questions, this "race-only" kit would be a very limited run because once the M62 Superchargers are gone, they're gone. They are not made anymore. The other option to use the MP62 that has the internal bypass valve isn't really an option because it would require a whole new manifold design, which due to the amount of interest in the supercharger kits and the price of the MP62 wouldn't be worth it.
As far as negative impacts of not having a bypass valve there aren't many. I spoke to John for clarification on this. You see since the M62 has larger rotors and the fact that the throttle butterly isn't really open at idle, it really won't be making positive manifold pressure. You may see the vacuum be in the -10 range instead of -15-20hgs but that's it. Its just not spinning fast enough to creative positive boost pressure at idle. The same should hold true while cruising. MPG may be impacted but maybe only by 1 mpg. Also another negative is that the M62 requires more crankshaft power to turn the larger rotors. So you will lose a little more torque down low but once boost is reached the extra power should more than make up for the difference.
With the current MP45 setup with the higher boost pulley as well as supporting intake and exhaust mods it should be fairly easy to get to 200whp. I say should be because we haven't had anyone local that is willing to put a header back exhaust on their car to test it. Usually people buy the supercharger kit because they want a easy to install, 100% maintence free extra boost in power. Supercharger owners typically aren't the horsepower hungry people like turbo people are.
This post is intended to be what the title says. Gauging interest. If there is not enough interest then this kit will not happen.

 

I understand.

(Check your other threads in here!!!)


What kind of pricing would we be looking at for the 62 kit then?

Has Tibbytib contacted you? He's local, has a full intake AND a full exhaust done.

I'm assuming that the 62 has higher boost potential than the 45?

My personal goals are 230 to 250 WHP. Supercharged would be my prefrence, and most of my mods are in my garage if you get a chance to look. Either way, I'd definately be doing my 1.8L Cam and P&P the head before I do any FI work.

 

What would the pricing be on this? I am interested. I wouldn't be able to purchase until late November or December. Even then I wouldn't be able to install it until probably mid January. 02.gif

 

I'd be interested depending on price

 

well that doesnt sound too bad, not enough to limit it to a race only mod.

i thought you were saying it would make you suck gas like crazy on cruise (15mpg highway lol)



damn straight, were greedy sons of b****es. wink1.gif

 

Hhhmmm, I am somewhat interested.

What kind of price are we talking about here?

Where is local, I am assuming right now that local is west coast? In which case nevermind.

I have always wanted to do the turbo thing, but considering my car should be mid-low 14's completely NA in a few weeks, maybe adding a supercharger would be enough for me (it would definately be more original and easier to maintain).

Anyway, please keep us updated.

Thanks.
