Hey CL,

I am curious about what type of horsepower I may have with the few performance mods that I have done. So far I have torquemaster plugs, SRT intake w/chip, and Borla exhaust. I know that stock is 300 hp/310 tq. Using the G-tech timer I averaged 13.9 at 101.9 in the 1/4 mile over 3 runs. The car has had its services done regularly and I have never had any problems with it other than the steering curse which I finally fixed with a new steering rack and aluminum rings. Any ideas or guesses on how much horsepower I can expect to have with my mods. I get asked frequently and I don't want to give inflated numbers. I haven't had the opportunity to dyno yet. Maybe this summer. Any guestimates from the pros are appreciated. Thanks.


KC

my guesstimate is +30-45 hp
drewgs4 was able to gain 38hp from just the srt intake

and i think some they gained 10hp from the tm plugs

no sheet? from just plugs

KC, I and several other folks have / have had that exact same setup from a performance perspective.

Do you have the newer 'race' ECU?

My GS with exactly the same mods dyno'd between 248 RWHP and 255 rwhp. I've seen others lower by 5- 10 and higher by 5 - 10 depending on how strong their stock engines are.

Chuck, Here is Mean Gene's post on the dyno for the TM plugs btw

Those numbers sound like what you should expect.

WOW im in the 13's? jesus i knew my car was faster but DAAYYYAAAMMM

what do you guys think ill be hitting once i get the TC in?

damn, i don't know about the hp, but under 14 1/4 mile, that's very fast speed we are talking about here... nice job!

Redgs4 and myself have the TM plugs, he has the FIPK , I have the RMM intake, He has the Tanabe Exhaust, I have the RMM, we both have TC mods, yada, yada, the whole 9 yards.

My car 245 RWHP 250 TQ

Redgs4 242 RWHP 254 TQ


Redgs4 just switched over to the SRT w/ecu. so I'd say it's time for another dyno run.

I myself have slightly more power adder mods coming by the beginning of summer.

Here's the results of our last Dyno Day meet:

Thanks DaveGS4 and RMMGS4 for the info. I didn't know there was a new race chip for the intake. I bought mine in 2003 direct from SRT. If there is a newer chip I can get, I'd like to know more about it.

I appreciate the help you guys provide. I got my list of mods right here from the forum. Glad to see others have done the same.
