I sold my 91 Firebird 305 tbi and bought a 96 WS6 Trans-Am on Friday. Its sweet ill post pics later. 305hp stock. Its got Ram - Air, Dual Cats, 3in American thunder Flowmaster Exhaust, granettie mass airflow sensor, 52MM Throttle body, Hypertech Power Programmer, Eibach Springs, Adjustble suspension(tour-sport) 3.23 gears, Automatic. Im guessing 320-330hp now. Im hoping for low 13s.

Just one question. I have a list of people i am going to race. Please tell me which ones i will beat and how bad. Thanks Alot!

*94 Z-28 Borla Exhaust, K&N Filter, Hypertech Chip, Automatic.

*98 3000 GT VR4 Turbo Mufflers, 6 speed.

*98 Z-28 LS1 B&M Shift Kit, Automatic.

*99 Z-28 LS1 6 speed, Borla exhaust.

*92 Corvette Flowmaster Exhaust, K&N, Jet Chip, Automatic.

 

Finally got it huh. Time to start kicking some a$$.

Looking at your mods, I'd say it was time for some SLP headers

91 Formula 1LE 1 of 46
305 TPI 5speed
1LE/G92/WS6

Paxton SN92 supercharger(SN93 upgrade), Ford SVO 24#injectors, Crane AFPR,SLP airfoil, ported/polished plenum, March alt. pulley,Crane Gold 1.6rrs,MSD coil,MSD6AL (5200rpm limit),Holley 9mm wires,Ac delco R43ts plugs,custom chip,Bosch O2sensor,SLP 1 5/8" headers,SLP catback,shortened shifter,3:73s w/Auburn posi,170* t-stat,JET 195* fan switch, Macewen white face gauges, Autometer gauges, Zoom hi-performance clutch.

 

By the way, about the cars you listed....

It will mostly come down to driver. Especially vs the vette LT1. The LS1 is likely to start pulling on you in the end from what I've heard, but who knows.

Like I said, headers would help with that .

 

Lets see these are probably the "guesstimated 1/4 times for each of those

Your T/A 13.4@105
94 Z 13.7@102
98 VR4 13.4@105(stock boost)
98 Z 13.4@104
99 Z 13.0@107
92 Vette 13.3@105

Very close

Those time are very generous, unless all the cars are running slicks or esle it's the track I go to that sucks. My experience at the track last Tues...The ricers (vr4s) you mentioned will probably jump you, but you'll catch up, but you might not have caught up to them by the end of the quarter; this is what I witnessed, anyway. You should take the 94 Z and the vette will beat you if he can drive. The newer f-bodies are awesome. I saw two 99 Ram Airs run 13.3's at 107-109 with stock eagle F-1's. I think you'll be able to run very close to the car's you've listed, except for the lS-1's. Once those engines are broke in they turn into some fast motha-------you fill in the blank. My cousin's got a 97 Trans am 6 speed with borla and a cold air kit and was only pulling 14.2's at 100mph, the same day (last Tues)the LS-1's were running 13.3's. All 98 and above f-bods and the VR4 I saw were running street tires, including my cousin.

 

THIS BOARD IS FOR STREET RACING AND THEORETICAL QUESTIONS!!!!!!!!!!


I DRAG 2

 

READ TO ALL MEMBERS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!I DRAG 2!!!!!!!!!!!!!!!!!!!!

idrag2, what's that last post about?? 305tbio3 asked a theoretical q and I gave him my theoretical opinion, any questions?

 

lol, your friends suck with their LS1's then. My friends are running almost STOCK 12.9's with automatics. Only thing they have is aftermarket MAF.

 

*clap, clap* Hooray for you Texas boys running 12's in stock LS1's. I DID say that the track conditions here in Indy suck. High humidity and drunken-******* track preparation employees are probably why that is. That's why the guys were only running low 13's here last week. My whole point is that 93-97 Z's are no match for the 98+ f-bodys unless they have a lot of mods. Peace.

 

In his post he asked if he could beat the cars listed, since no1 seems to have raced any of those cars its OK to get an idea of how it will do on the street by comparing 1/4 mile times, for the street though. There is another board for actual drag racing.

Well, outside the ***** comment, I agree. The VR4's AWD launch will holeshot you to hell, but at higher speeds, the AWD system becomes quite parasitic, around 30% drive train loss to be exact. So, even though the TT 3.0 is making 320hp, its losing 100hp through the AWD system. You'll kill the VR4. The 94 Z-28 will run similar times to a 96 non-WS6 T/A, and since you out-mod him as well, you should beat him pretty good. The LS1 cars are likely running low, low 13s, likely enough to beat a modded LT1. A lot of people will tell you that LS1s are capable of 12s from the factory. Although this is true, this will not be a really common occurance. I'd be mostly worried about the 6-speed Z, since the other is virtually stock. (The B&M shift kit's performance gains really are minimal at best) As for the Corvette, the first thing you should do is check for any badges that say 'ZR1' , if there are none (it probably isn't a ZR1), the race will be close, but should favor you slightly. There isn't a huge margain between LT1 Vette 1/4 times and LT1 F-body times, and the Vette IRS can be difficult to launch at the drag strip. The exhaust probably adds 15hp, the K&N; 2hp, and the JET chip; maybe 5hp if he's lucky. This race will be close, though. Hope this helps!

I would bet you would be happy with 13.80 in the quarter. I don't believe that there are stock auto ls1 cars in the twelves. Hell, most of them I see are high 13s. I have beat everyone I have raced and been side by side with a 2000 auto ram air. If those cars are almost twelves, so was mine. (before heads) And I ran 14.00 at 100.
