on a dynojet 248c. the car has SLP CAI, !TB, vortech elbow, SLP 96-97 headers, random tech dual cat y pipe, flowmaster 30 series catback and pcm 4 less tuning (160 t stat, fans, knock sensor turned off), i expected a little more, but the car was only running 8.70s@81-82mph in the 1/8 tonight. the 60 fts were in the 2.1s. i think it needs a tune up. it made 274rwhp and 313rwtq. ill try to get the dyno sheet posted.

GM Hot Cam Kit 1.6 Roller Rockers LT4 Springs 52mm TB Jet Hot LT's, NO CATS, True Duals, 12in Bullet Mufflers, 2.5 inch Stock Box w/CAI Filter on Bored .030 over TB Bypass 4 Gauge Rewire Kit Custom Tuning The numbers were made before i put the TB on but that wont give me a ton of power lol but the top end feels better. And that Rewire made the top end smooth out a ton and gave me 10 rhwp  But ya my numbers bounce from 295 all the way to 330 so i dont get an accurate reading. But its all about how it performs on the street and track rather than the dyno |

not bad i would think you woudl have got a lil more out of it.
I made 275rwhp and 315rwtq with just a cut out but with it closed the car only made 264/302
then i added hooker LT's and it put down 290/325 untuned then with tunning i did 363/379 but that was with a few more mods ;D

does the car feel good?does it feel strong? that's what matters a dyno has so many variables that can change go with how strong your car is running.  |

That might be a tad low as far as numbers are concerned but as you said, it feels strong. That's all that counts. Also could be the dyno correction factor, weather.

What was the weather like when you dynoed? There could be several factors that could come into account that would contribute to the slightly low dyno numbers. Then again, you know what they say, dyno numbers don't win races  |

it was hot. my car doesnt fall on its face after 5K like everyone elses. the car runs better when i shift at 6K instead of lower in the powerband.

i didnt a/f it on the dyno. theres more ET in it. its best pass in the 1/8 was a low 8.60@84. ive gone low 8.40s at as low as 79 in prepped stock motored mustang i had.

why is that all knowing LS1 owner? its run 84mph in the 1/8 in good air with the worst exhaust known to man, a pcm4less tune and a CAI. sounds to me like it just needs to pull better then 2.1 60' times. maybe i should get someone smart like you to come down here and tune it for me.

yeh..... well you wanna be ana$$about it .....
FYI i also own a 97 formula , have also owned a 95 formy and 96 ta, funny how people just assume things....
first ... you have a 30 series catback? if so then you are saying you have a 2 merge into 1 tailpipe ? you know the setup they sell for 89-92 fbodys?
or did you mean you have an 80 series catback which is noted time and again for being a bad mod for 4th gen fbodys?
84 mph in the 1/8 is about 104-105 at the big end, thats right on target for 274rwhp. so the dyno is not off, but my point was you have more then 274 in your setup.
hey tough guy you want someone to give ya an ata boy you got plenty... i offered some advise, YOU took it and desided to be a smart ass

for the record, if you did mean the 30 series single out exhast, then although it funny looking, its not too bad on the flow side. the 80 series is MUCH worse, the trouble is in the cross flow section which the 30 series does not have...
however you probably have another 10 hp in tuning, and for $30. another 7-10 hp from welding up a cutout...

i thought you were being a smartass, so i decided to start. ill buy you a beer. anyway, i have the single out flowmaster, not the 80 series dual out. i also have a 3" bullet that im thinking of welding in place of it. the car would probably pick up some more with longtubes instead of the slp 96-97 dual cat headers, but ive heard conflicting stories on that.
ive seen 3" single setups make 800rwhp on turbo cars. so i dont think its that big a restriction on my little no power making motor. hell i made over 500rwhp on a single 2.5" downpipe out of a 60-1hifi turbocharged 5 liter.
the maf is unported still. im gonna try to get into the mid 12s with the power i have if i dont buy that 01 nbm z.

i thought you were being a smartass, so i decided to start. ill buy you a beer. cool... not a bad idea, as long as you dont mind loud all the time. i run LT's no cats to a h-pipe true duel set up with 2 bullets... i love it but most people wont ride in teh car for more then 5 mins before they are complaining that there ears hurt... thats why i recomend cutouts to most. but yes a bullet is just as good. there should really be no conflict on this. f-body LOVE long tubes, if i may throw a sudgestion at ya, i would go with stepped long tubes, they scavenge more and make better power thru the whole curve. yes but you said the magic word... turbo, the exhast you normally need to flow strait out is now being slowed and used by the turbo to spool, so it does not need alot of flow after the turbo. porting the MAF does little but not much, if your plans are mid 12's with 274 rwhp.... you are gonna need to get the car down to about 2500 lbs lol.... my lt1 formy hardtop is down to 3000 lbs.... only 500 to go |

i know of a stock motored car running 12.20s@108 with the same headers i have. his car is 300lbs lighter then mine tho. 4.30s and slicks will get the 60' time down where itll run 12s. with a 2.1 60' it runs 8.60s. with a low 1.7 60' i should be able to get it into the 8.20s at least.
the thing about the turbo cars is that they do require flow, thats why flowmasters can plug up about 40rwhp on a 500rwhp turbo car. my point was, 3" single shouldnt hurt my car more then maybe 5rwhp max.
