The SQ is not a specific trim. The V1 and the V2 SQ are both S-trim centrifugal superchargers. The V1 is the original style and has a much louder whistle to it, the V2 SQ is the "superquiet" and has a much quieter whistle sound.

Your rear end should be fine, breaking the rear end usually happens when launching from high RPM. Not from having too much horsepower. As long as you arent runnin at the track dumping at 5kRPM on the stock rear end I think you will be fine.

So basically, if you want to hear the whine get an S trim??

Lol they are both S-trim...the difference is V1 or V2 SQ but both are S-trim (same size). And if you want to hear the "whistle" really loud get a V1.

okay...but on mph site it says you get to pick from the s trim or an sq...thats why i wasn't sure...so i guess ill go with the s trim

i was also thinking, if i was to buy that kit, i would also need a boost gauge right? And any thoughts on pulleys and powerpipes? or should i just keep it how it is and see how i like it first?

Car_Ramrod

if youre gonna get a powerpipe...you might as well get it when u get the supercharger installed...that way you can get it tuned for the psi you will be running at and be done with it. and yea might as well get a boost gauge and an a/f gauge or something. at the very least it looks bad *** on the a pillar haha.

and senior in high school? where are you getting the money for a supercharger man? share the wealth! [:@] lol. good luck.

There is a "S" and a "SQ" V2 blower. The SQ has a differently cut impeller than the S. The SQ is quieter, and Tim at MPH has proven that it also makes slightly more power.

The MPH kit is extremely complete, and the best part is you get a tune from them. I have never seen a tune that was so accurate right out of the box. They were able to tune my car better never having seen it than my local shop could before I even had boost!

The only thing I recommend is either getting the power pipe right away, or asking them if they can send ya a seal from the powerpipe kit. The stock vortech seal is almost impossible to fit around the 90 MM lightning MAF they send ya.

If/when you do go this route, PM me if you have any questions. I did the install in the garage just a few weeks ago, so it is all still pretty fresh in my mind.

BTW that is just sick that you only have 37,000 on a 98 GT. Talk about mint condition!!!

Thanks alot 200gt4.6 for the help....

I am definately going to go with the Mongoose S trim kit with a powerpipe....

what boost do you guys recommend i run?? i was planning 10lbs...does that sound too high/low?

I can't wait till this goes through, from what you guys are saying this s/c sounds awsome

Car_Ramrod

i think you should probably be fine with 10 lbs....i think the maximum recommended safe amount is 12.

I thought 8# was about max? I mean I relize you could run more but that realy wears on the wrist pins at 10-12# on a factory motor. Also with longtubes........your pretty much gonna crap when you see how much power you end up with.
