Re: HP difference between 98-02? 98's were kinda dogish for a LS1, in 99 they upgaded to larger injectors. 00 they have a little bit larger cam and free'er flowing exhaust manifolds (kinda like shorties) 01-02 little bit smaller cam than 00 but the LS6 intake manifold and no EGR, with the same exhaust manifolds.

Re: HP difference between 98-02? I would have to guess 15rwhp. give or take a little. it might and most likely is if he is a good driver. if they are both A4's, get a larger stall thats all!

Re: HP difference between 98-02? Mine is the A4 and his is M6. But, i have all modded intake with headers, ORY pipe and magnaflow catback and 3:42 gears. Will i have a chance? He took his to the track and ran a 13.14 @ 108. I have never been to the track. I dont think mine will beat that.

Re: HP difference between 98-02? when you say that you have a intake... what do you mean, LS6, or aftermarket, or like lid and bellows? Headers, is that LT's? I think even with the stock stall you should have no problem matching that or beating that ET. now you have a LS6 or aftermarket intake manifold with a lid, and LT's w/ ORY pipe, I think you should be almost touching 12.9, you should run 13.0x with no problem

Re: HP difference between 98-02? It has TSP lid, k&n, bellows, ported TB.. Pacestter LT and what i mentioned obove.. I guess i should have been more clearer.. sorry seadoo. So, should i get a Torque converter next or and aftermarket Intake manifold? Just a curious and proud f-body owner!!

Re: HP difference between 98-02? save up and get a 3500 stall!!! you can eat him alive with that setup and the stall, even if he has headers, etc. I really would not go over a 3500 if you drive your LS1 as a daily driver!
good luck man, but I would run him now to see how you do. let us know!

Re: HP difference between 98-02? You need a Torque converter or you'll never beat him unless he can't drive or misses a shift. He's got probably 20 rwhp more then you because he has both LS6 intake advantage and M6 less drivetrain loss advantage. It's going to be very difficult to compete with him if he can launch and shift well until you get the torque converter and tires to put that power to the ground.
However once you get that and get a good 1.6 to 1.7 60' time technique down then the tables will turn and he will be struggling to beat you. He will trap higher but you'll cross the finish line first and that's what really matters (to me anyway). But your a good $1500 dollars worth of mods away from beating his car at the track.
Good Luck and don't be ashamed to run and lose. It builds character and gives you valuable track experience. Hey I gotta find some reason to be happy about a loss. It's all in good fun.
Good Luck and welcome to the wnderful world of LS1 A4's. You suck at the track at first but can rule it later on with money well spent.

Re: HP difference between 98-02? Two LS1 F-bodies, regardless of the year, racing off the line will come down to traction at the start, all things being equal. I'm not convinced at all that the M6 has any advantage over the automatic either. If anything I'd say the automatic has the advantage, especially with a higher stall.

Re: HP difference between 98-02? yes and no... the only real advantage of a M6 over a stock stalled A4 is when the M6 shifts it will learch forward. I know, I have a 00 TA and a friend has a 02 SS M6 when he shifted it learched on me. he runs 12.90s w/ a best of 12.80 on F1's w/ a 1.98 60'. he has SLP center mount catback, and a Direct Flo lid.

Re: HP difference between 98-02? Well, i did it. Since i am new at the racing scene didnt know what to think!! But, guys it was awesome racing last night!! Hell, still gitterish!

Re: HP difference between 98-02? it was my impression that '98s had the largest injectors of all the years, i do believe running 28#s. the latter years moved down to 24#s or 26#s. however the other points *are* true, concerning the cam/intake differences. the '98/99 were still running a ls1 intake and had the unfortunate egr mess to deal with.
a 13.6 for the first time on the track is good **** man! never be ashamed of any times, learn what you can from them. Its always valuable track experience!! Plus its hella fun.

Re: HP difference between 98-02? "in 99 they upgaded to larger injectors."
This is incorrect. In '99 they went to smaller 26.4 lb/hr injectors. In '98 they were 28.6 lb/hr. In '01 they went back to the larger injectors.

Re: HP difference between 98-02? No. You gain more power by getting more air into and then out of the engine. Add fuel as necessary. 
BTW, the factory injectors are adequate for at least 475 RWHP.

Re: HP difference between 98-02? That is a good time you ran, waterbug1999. That is the exact time i did in my 99 A4. Hey Colonel, is there any HP at all to gain by putting the 28lbs injectors in my car? I wonder why they went back with the bigger injectors, there has to be a logical reason for them going back to the bigger injectors.

Re: HP difference between 98-02? Read above. 
Why did they change back and forth? Who knows. Maybe it was supplier related. For maximum HP at WOT you need a fuel/air ratio of about 13:1. The stock injectors can handle that job all the way up to about 475-525 RWHP (depending on year and drivetrain among other things.) There is no power advantage by simply going to bigger injectors. Assuming you keep the same mixture and timing advance, you will make no more power with 42 lb injectors than with 26 lb injectors, for example.
