I'm looking for mods to increase my HP, but not major stuff like FI, cams, heads, and nitrous. I thought about CMDPs and UDPs, but what else is there to increase horsepower?

I'm having 4.10s installed on May 12th. I also thought about a 1 piece driveshaft, but I'd like to see what else is out there.

 

There's really not too much unless you go F/I, cams, heads, or nitrous. Go with a set of CMCVs and UDPs. I gained 12 rwhp. A lot of people say you lose part throttle power with CMCVs or low end power. This is untrue. A lot of tuners have just accepted it and haven't spent the time to tune them properly. Justin at VMP Tuning tuned my car for them and I gained power every where including part throttle power and I even gained .5 mpg. It's possible that was from the UDPs though, more than likely anyways. An aluminum driveshaft will help put that power to the ground. I've heard they are good for 2/10s of a second in the 1/4 mile which is pretty damn good IMO. Do you have cats? You could do a O/R X Pipe, it's worth about 3 rwhp.

 

I forgot that I took my mod list out of my sig and just put the brands. I already have full exhaust: MAC LTs, O/R Prochamber, and Boomtubes.

I think I'll get the CMDPs from Brenspeed, he'll redo the tune for free since I got the SCT from him. I may get a single tune file from VMP just to see if it really does make a difference.

Would a dyno tune get rid of the low end torque loss from the CMDPs? If it would I can just have that done for a little more than the VMP tune.

 

Is this primarily for track or street?
1 Piece Drive Shaft was worth 0.18 and 2.08 mph on my car. If your not already in the 12's you will see bigger ET gains.
You can take 100 lb of rotational weight off the car with Fats and Skinnies if this is a track set-up.
A shortbelt is an easy gain at the track. Only takes a couple of minute to swap belts.
After that Longtubes if you dont have to suffer through emissions inspection.
CMCV DeletesAnd UD Pulleys are worth a little.
Electric Waterpump and remove the belt completely at the track.

Most controversial would be the GT500 TB. Many claim its worth nothing but it picked up Ron (Spydershaft) a tenth when he was already in the low 12's.

For a Automatic the biggest gain in ET would be from a PI Converter.

 

get a good TC, you wont regret it

 

It isn't a track car, only used on the street. Good suggestions though for if I ever do go the track car route.

 

A good tune won't lose you any power or torque from the CMCVs. I'll be posting a big write up here when I get the time to do it. Along with a bunch of dyno graphs.

 

FI FTW!
