Supercharger

[voyager7]

My son has a 1999 Cobra and he wants to add a CAI now and add a supercharger in about a year.
What have you guys found to be the best ones to use?
Please give both pros and cons.
His car has 17K miles.

Thanks in advance,
V7

Can't use CAI with the supercharger, I'd do exhaust first. Proower, Con:Fuel mileage, there's more for both lol

 

[01yellercobra]

I agree with blackvenom. Open up the exhaust to get ready for the blower. Any idea what blower he's planning on going with?

Jlt is my favorite. But as the previous guys mentioned, can't run both unless its an Eaton or kenne bell.

What mods are on the car now?

The easiest route with supercharging would be to go with a Centri, an Eaton swap takes a lot more work. As others have said it's best to open up the exhaust first as they are very restrictive from the factory.

The car is bone stock.
He plans on doing the exhaust first.
He likes the sound of the flowmasters.
What size pipe should he be looking at if he is going to sc it later on.?

I think he is looking at a Kenny Bell.

The kenne bell is pricey but makes for a fun street car.

I've got the Flowmasters and I don't really like the sound, but its a matter of personal opinion. He should also consider a midpipe and longtube headers to really open up the exhaust closer to the engine. Stock headers are pretty bad. If you are asking about midpipe/catback exhaust diameter, I would say go for the 3" diameter with a boosted engine.

it's even better at the track...VHT makes 1st gear usable lol

2.5" will be fine for exhaust. I was close to 600rwhp with 2.5" pipe. The KB is a good set up. But just make sure he realizes that he can't upgrade the blower. The only way to do that is to do the Eaton swap. How mechanically inclined are you two?

 

[Black*Death]

2.5 or 3 inch....I think 2.5 inch is best....I would do a full exhaust headers, midpipe and IRS mufflers..

Kenne Bell is overpriced for what you get. Eaton swap would be much more cost effective and allow for different blowers including Kenne Bell models. I wouldn't run flowmasters if you want performance gains. They will make a lot of noise, but thats about it. Borla, Dynomax or Magnaflow are more performance oriented and are good quality.

2.5" exhaust should be fine unless you really want to make some big numbers. Most blower guys make 600 rwhp on 2.5" exhaust.

Chambered mufflers on a modular motor is the biggest mistake you could ever make imo.

I'd have to disagree. While I'm not a fan of Flowmasters, I really liked my Macs with the catted X. It sounded good and I got a lot of comments on it.

BTW, just wanted to say, wish my dad was as cool as you haha. I'm 22, in the military, and he still screams at me to leave my cars stock and that I'm an idiot for modifying them.

On the topic of the blower...Procharger F1a at about 14 psi should hold just about anything off. My favorite sounding cobra with a similar set up on a F1a

MAC Flowpath chambered mufflers are very popular with SVT Cobra guys myself included:rockon:

An F1A at 14 psi will grenade that stock shortblock into many pieces, I didn't hear the OP saying he was gonna build his sons motor for that boost level:shrug:

 

[BlackVenom99]

Things all go Boom even built motors, it's all in the tune...to an extent. Best advice for anyone looking to supercharge is to plan a motor build.

Plan for the worst, hope for the best.
