HP gains and sound quality? - Need your opinion!!!!!!

[Vipermann1]

I am looking to upgrade my 2000 Viper RT/10 with some performance parts from Dan Cragin at DC Performance in Los Angeles. (Their service is great!)

Question #1 - What HP gains should I expect from each mod?

K & N Air Filter ... ? HP
Smooth Tubes ... ? HP
Borla Headers ... ? HP
Corsa 3inch Exhaust ... ? HP
Randon Tech high-flow exhaust ... ? HP
Aluminum Flywheel ... ? HP
DC Performance Custom Computer Programming ... ? HP

Total HP gains ....... XXXX HP

Question #2 - What will the change be with respect to the exhaust note or overall sound of the car? Will it be way too loud?

Thanks,
Vipermann1

Dan has an onsite dyno, and can probably give you the most accurate answer. He is knowledgeble, honest, hard working and a great guy. His shop is first rate, and has a stellar reputation.

I had a similar set up on my GTS (Except used SVSi headers and got about +50 hp. (Your experience may vary)

Looking to do the same kind of mods, and thinking to change the rocker/roller as well, did you forget them or just think it is not necesary?

Dan did my B&B headers and full B&B exhaust. We took the cats off since i live in Illinois and have no emissions. Plus he did a good deal of warranty work and helped me by inspecting the car for me because i was buying out of state. I didnt even see the car besides a few pics. Dan did an awesome job. Great guy!

OK, Dan did my 2000 RT/10 and I did before and after dyno tests at the same facility, mods were:

K&N Filters
Smooth tubes
Balanger Headers
Balanger 3" catbacks
Randomtech Hi-flow cats
light weight flywheel
3.55 gears

The car gained 41 rwhp and 50 rwtq and sounds great.

New Mopar 1.7 RR on Viper alley.com classifieds for $850!

Do the 1.7 RR when you do the heads.

My guess would be 35rwhp-40rwhp, might be more. The difference in sound is worth it if you lose 50 hp!


Well, maybe not, but it's alot better!
