how much horse would you predict?

**Freddy** · 03-27-2013

i got a 99 gtp its got headers high flow cat cat back 1.7 roller rockers and cai. how many horses do you think i could get and is there anywhere near abilene kansas i could get it dynoed?. i might trade it for a stang but the guy wants to know numbers so if i could get a rough estimate that'd be nice. tryin to get away from grand prixs cuz i almost got in trouble with the cops and now my car is marked.

um 210whp??? maybe

**Freddy** · 03-27-2013

have you had yours dynoed? if so what mods to the engine?

**Iceman6669** · 03-27-2013

I have not personally had mine dynoed... But stock they make 200whp and yours dont have a lot of mods..What pulley are you running?

**Freddy** · 03-27-2013

3.2 also forgot 1 step cooler plugs and msd wires

**Iceman6669** · 03-27-2013

a 3.2 with just headers and 1.7s???

**Fivefingerdeathpunch** · 03-27-2013

If its running correctly and has a good tune maybe 240-250 hp???

**Freddy** · 03-27-2013

runs good with no kr

**Iceman6669** · 03-27-2013

with a custom tune I am guessing....

**Freddy** · 03-27-2013

yeah

**Iceman6669** · 03-27-2013

with like 10* of timing and running an 8AFR?

**Freddy** · 03-27-2013

i dont recall it was a while back

**Iceman6669** · 03-27-2013

Well anyway I would guess that you are around 230ish. maybe 240 range.

**Freddy** · 03-27-2013

ight thanks for the help

**GMR Badass** · 03-27-2013

I'm going to guess 235whp. Running too small of a pulley for that setup and the custom tune probably does have a lot of timing pulled to keep it from seeing any KR.
