ProChamber claims 22.2HP yay or nay?
 

I put the chamber on my car yesterday. It feels faster, i'm wondering if it's just phycological(sp) or did i really gain in HP?
Would anywhere close to 20HP be possible?

Don't even get me started on Mac Products....

As far as the gain in HP, I think your car is pretty close to stock right, at least, it's still NA, right? If it is, I would say 20hp to the wheels is pretty optimistic, but at the crank, it's a possiblility, though the actual gain is probably closer to 15. Depending on the model, some cat pipes can be very restrictive, so changing to a pipe with no restrictions can be a real help. How do you like the sound?

The sound is amazing! I've also got Flowmaster ;)

The rev's seem to spool up sooo much faster. I didn't get a chance to hammer it (roads are still cold/no traction) but yeah, i'm wondering i'm gonna gain in the 1/4. At least it feels like i might?

If you don't pick up a tenth in the 1/4, I'll be surprised, cause the pipe should be good for at least 10hp. Let us know.

Hey Stoplight I see you feel the same as me regarding MAC. Never again buy their stuff.

I'm getting tempted by that ProChamber. But I just can't seem to justify the added cost over a regular $120 h-pipe which will probably make almost the same power.

I think their 20hp claim is possible on a modified car, but on a stock 4.6L, gains will most like be in the 10-15hp range. That's still good for a tenth or two in the 1/4, so go racing!!

heres how i justified getting a bbk offroad h-pipe & flowmasters

the hp gain from both together lets say is 20hp, thats worth about $200.

the sound is worth $1,000,000.

I think their products are fine, but the service.....let's just say I'm done with them for a long while....

I have the MAC prochamber and i dont like the sound of it, im getting a 3" all the way back with flowmasters, if anyone is interested in buying the prochamber or the whole system please e mail me at frankie_t51@hotmail.com The whole system only has about 700 - 1000 miles on it. and its off of a 85 GT so it will fit 86 - 93 lx models and 85- 86 gt models
