Thinking I'm finally going to get a SC for the coupe. I want to keep the Shaker, so other than going with a Super Shaker (which, to me, seem way over priced), I'm looking at a centri blower. Seems like Vortech has the best reliability out there, so I'm trying to decide between the V3 Si-trim standard or HO versions. Being that my car is an auto, and I'm not looking to replace parts on a regular basis, I know I'm not going to hit any super-high HP numbers. My goal is somewhere between 425 and 450HP. Anything in there and I'm happy. Anything beyond that and I'm thrilled. But I really don't want to sacrifice the drivability of the car - just want the extra power under my foot when I want it.

So I guess my question is this: Knowing that the HO kit is going to run me about $1300 more than the standard kit (as either way I'd go with the polished version), and installation is going to be more because of the heat exchanger, is the HO kit worth it based on the HP number I'm trying to reach and the goal of still maintaining drivability? My thinking is that even at low boost numbers, having a heat exchanger will add to the life of the blower, so the extra $$ might be worth it there alone.



BTW - These are the kits I'm looking at:

Brenspeed - Vortech V3 Standard

Brenspeed - Vortech V3 HO

Can't beat Brenspeed's packages and pricing - just wish I was closer so I could have them do the install too!

I have the standard Vortech on my '07 GT Automatic coupe. If I could have afforded the HO model when I bought it, I would have, but I was on a very strict budget and **** lucky just to get any blower on my car. The HO will net you an extra 30-40 rwhp over the standard kit and keep the car running cooler, so it's certainly worth the extra cost.

That said, my car is bone stock except the standard Vortech V2 S-trim kit, stall converter, 4.10 gears, X-pipe with high flow cats, and drag radials. I've run a best 1/4 mile of 11.85 @ 113.5, which is pretty dang stout for such a basic car. The car really pulls hard from a roll: factory stock 0-100 mph was 13.9 seconds per most car magazines (GT automatic), yet I do it in 9.9 seconds for an improvement of 4 full seconds!

All in all, the standard kit is a lot of bang-for-the-buck. If you can swing the HO kit, do it, but don't feel bad if you "only" get the standard kit.

Thanks Brian - great info!

In hindsight, I wish I would have gotten the Paxton air-to-air IC with my Vortech. Then again, I feel that my car is quick enough, and I very much like the way my setup looks.

One more thing Jeff, no matter what supercharger setup you go with, I highly recommend that you get the car dyno tuned. If you insist on running any provided tune, at least get the A/F verified on a dyno before dropping the hammer. Just saying.

STL-GT

Thanks Bill - great info. I agree that a dyno tune is a must. While I'm sure Brenspeed's tune is solid, I think having the piece of mind of having the setup verified on a shop dyno would be worth the $$.

So I asked basically the same question on a local Mustang board and a couple of folks have said that Paxton is a better way to go:

Brenspeed - Paxton Polished SL

Anyone here want to chime in on that recommendation?

Also got the suggestion to look at this:

On 3 Turbo Kit

One of the shops sort-of in the area is their #1 reseller and installer. Any thoughts on that?

I believe there is no difference between the Vortech and Paxton.

Thanks for the info Len. Had no idea they were virtually the same company.

I'd love to get either one myself but that warning about not running the car below 25 degrees is a bit of a concern. Can anyone shed some light on that? Is there some truth to that or are they just covering there fannies?

between those two kits the paxton 2200 has a higher CFM and can support more power than the Vortech V3, the vortech has an air-to-water intercooler and the paxton has an air-to-air.

Here's more detailed info.

Well, I think that makes my decision on the blower - Paxton 2200 SL it is. Now I just need to decide where I want to get it installed locally

SONICBOOST

The paxton 2200 also has two bypass valves which make a really cool pssssshh sound when shifting

I've also been speculating on adding a supercharger this winter (I've got a winter car, so I can have the 'stang apart and do the install myself). I'm undecided as which style (centrifugal VS TVS) and have been looking at all brands. Most ad copy states that their S/C's are made for safe boost pressures on stock motors, but I'm guessing that those are low mileage machines. My biggest concern is how much boost I can safely pump into the stock engine. This car has 60K miles on it, and while it's not a track dedicated machine, I can say it's been well broken in......SO....anyone out there boosted a mid- to high-mileage 4.6?
