  • Guestimating my rwhp...

    Ya I know the only real way to know how much power I'm putting to the pavement is to either hit the track or the dyno but right now not in a position to do either (in school and BROKE!). So my car buddies keep asking me how many ponies I'm putting out with my mods and I really have no idea so could someone who has similar mods tell me what they put down? Here are my power mods:

    SLP Loudmouth cat-back, whisper ram air, whisper lid, K&N filter, and a TB spacer/coolant block from ZZP. Soon I hope to have HPTuner's programmer and a new high flow cat. Anybody know what I should be making currently though? Thanks

    180 at the most. probally more like 175ish

      There is about a %15 loss of power from the engine to the wheels. The Z-28 camaros with the 5.7L 275 HP Engine put out 233HP at the wheels, so theoretically a stock a stock 3.8L Camaro would put out 170 HP at the wheels. So you are probably getting around 180-185

          Was that 201 with a 5 speed or auto though??? 5 speeds just dyno higher. I'd guesstimate about 175rwhp on your auto.

              lid filter SLP CAI and a SS muffler (stock from there forward) I did 174RWHP and 216RWTQ through my A4... Youre probably right around there, 180 at ABSOLUTE most.

                heh I was never aware of a 275hp 5.7L Z28... 310 hp on the other hand...

                Although Im not sure what that is at the wheels, most people that dyno stock usually get around 305 stock I believe, some people on here have it posted in their sigs Im going off that...

                I know the 200 rated for our cars is bull**** though

                  The 93-97 Camaro/formula/trans am had the 275 HP (factory rating) LT1 engine in it. The 98-02 Camaro/formula/trans am had the 320 HP (factory rating) LS1 engine, in reality the ls1 engines were making 350 hp and the rating was lowered in the f-body because GM wouldnt want a car with the same power as the vette for 20K less.

                    i wouldn't call it overrated, i beat a lightly modded 3.0 200 bhp manual supra with my 3.8 200 bhp very lightly modded (flowmaster and cai) automatic firebird. we raced to 110 and by then i was 3 car lengths ahead.

                        You realize that the 200 hp rating for our cars is not at the wheels, yes?
                        Maybe not though since you didn't know about the LT1 even existing. [img]graemlins/stickpoke.gif[/img]

                          I thought LT1s just had like 10 or 15 less like around 300, it's not that I "Didn't know they existed" so stop putting words in my mouth n00b. Your logic reverses itself for the LS1 so how do you explain that? ;) (See above posts)

                          Yes Im well aware its at the flywheel not the wheels... See where I called bull****, maybe you need hooked on phonics cause your agreeing with me trying to sound like I was wrong, again where is the logic? ;)

                            The 200 hp rating is not bullsh** GM just rates hp at the flywheel. People just need to understand that as a point of comparison to other horsepower ratings.

                              I love how people point out what I already stated [img]smile.gif[/img] Do I hear an echo? You have your opinion and I have mine on how they rate their horsepower, however, and I'm not arguing semantics.
