Not sure about who would win (it seems alot of people think the LSx is just unbeatable-it's not...), I just want to ask you if Dana knows that you have a B&M shift kit in a ProBuilt trans.....?
i dont think i'll lose.... im going to compare.... my 4 bolt forged block is stronger than the six bolt ls6 block....... the 180's flow very close to ls1 heads.... my hotcam is bigger than the stock ls1 cam.... my tpi is ported and siamesed to the max and pulls to 6 grand, id say my probuilt 700r4 with shift kit and a 2200 stall should do well against the stock t56 6 speed...i say i will pull on him during take off but he will reel me in, but by the time he catches up to me the race will be over.....
If he has "full" bolt ons, its capable of running in the 11's if the track and driver are right. Your's doesn't have that capability. If he has just the normal bolt ons, he should run mid 12's. Your's might have a chance at that.
Block strength doesn't mean anything at those power levels. LS6 blocks can easily run in the 9's, they are plenty strong with 6 bolt mains.
if he can drive, you may be in trouble. with a good driver he'll be running really low 11s. you definatley have a chance though, its not like youre racing him in a minivan. from the look of your mods list it looks like youve put at least a couple thousand into your car. just be confident in your car and in your abilities and hopefully you can pull it off.
yes you are right ive spent 4 to 5 grand on everything i have.... my complete mod list is in my sig.....well i know my car is capable of low 12 secs if i hook right..... maybe with a 100 shot of nos i would win.......
Buddy of mine had an 89 Formula, 355 Trick flow twisted wedge heads, good cam, putting 338-345 HP to the rear wheels. (T-56 in his car). He really couldnt do anything against my 01 WS6 Stock. Oh wait......thats right I have a K&N with a flow master muffler......Big HP gains there, you know.......He also has headders and GMMG exhaust. Now he just redid his engine and is putting down 370Hp or so to the wheels I doubt I can do anything with him. I know they can be beat. but with what you described you have a simular set up as to what my buddy had. Dont miss understand it all depends on the driver. It will probably be really close either way

stock ls1's put about 300hp to the wheels...if he really made 338-345whp...he "should" have beat you..sounds like he's not the best driver with a t56
but he also had K&N's and flowmaster catback and looking at his sig its a 01....if i remember correctly 01 and 02 got the ls6 intakes......so it should have abit more than 300..... for some reason they get huge gains to things like that compared to our engines.....
my 02 ws6 with slp lid and a k&n filter dynoed 325rwhp/342rwtq through bad cats and my car ran a 13.32@108mph with a 2.24 60' foot, my first time at the track with the car and my first driving a stick. since his car is a full bolt on (assuming headers, full catback) he should be dynoing close to 340+rwhp and should be in the high 12's in the quarter and his mph should be in the 110-112mph.

Idk this one is a little hard to decide on but if he has full boltone and can drive i say the ls car ftw my buddy has a 02 z28 auto and with a slp lid and borla exhaust he put down 305 rwhp. Shoud be a fun race but watch out those cars top end is rediculs
yeah it should be a fun race... i wanna be able to beat those bolt on ls1 one cars from a stop.... if i cant do it with an max effort tpi then i know nos will beat them.... this is my tpi as of now....took alot of time and effort to build this... i want to have one of the strongest factory looking TPI cars out there......

You are correct about the ls6 intake. However. AN LS1 IS AN LS1. The 98-00 models had a slightly larger cam, while the 01-02 got the ls6 intake power was kept at the same level. All m6 ls1's dyno 300-320 at the wheels, which is roughly 360 at the crank. If he has an 02 m6 firehawk with full bolt ons that means he is putting down around 350 at the wheels, 400 crank which is good for bottom 12's. LS1 cars pull hard all the way to their top speed of 165. I think your TPI is what will lose you this race. It cannot even compare with the ls1's intake. Look into a better intake. DO NOT RACE HIM FROM A ROLL. Your best bet is from a dead stop. The shorter the race, the better. Good luck, your going to need it.

i think i need to drive in a ls1 car... my car is the fastest car i have ever been in.... even tho its still tpi, it really doesnt feel like one.... more like a superram...pulls really hard.. my car is definitely a sleeper.....
I think you could beat one in an 1/8 mile race. Im not sure about the 1/4. From a roll you would probably get beaten badly. They pull hard all the way to 165. Its not really a fair comparison. The l98 is a great motor but it was not built to go up aganinst an ls1 plain and simple.
took out a 2003 ram air ta man what a rush ... thing is fastand the 6 speed my god so much nicer really want to find a stick third gen im tired of the 700 r4

ta ws6 4th gens were 98-02. you can find them fairly cheap. I got my 98 6 speed with 22,000 miles for 12.9.
I'd be careful my pops 99 z with just longtubes, slp catback, slp lid, and my dynotune put down 347rwhp and thats on a conservative tune through an automatic, just my .02

Those are strong numbers for just exhaust and intake. ls1's never surprise me. All it really takes is exhaust and lid to see 400bhp.
No offense to the OP, but to end all the "bench racing" - beg, borrow, or steal some drag radials and take it to a track. It appears you have a stout set up for a TPI, but until you see what it really can do in the real world vs. on paper... it's just talk.
I have an A4 LS1 car, see sig. With just bolt ons, nothing internal, I went 12.20's in the FL heat on an N20 tune. (less timing & fatter a/f for the jug) Now, it's a forged bottom end, heads/cam/FAST 90/full bolt ons - no nitrous. You can see it's over a second faster than my old bolt on times.
I enjoy tinkering wtih my 91', and buying used parts on a budget. But I knwo I'll never come anywhere near 12.20's with just bolt ons, and nowhere near 10.70's with a TPI intake set up - even with heads & cam upgrades. I have a soft spot for these cars, and enjoy it for what it is. The guy with the fatter wallet, and more willing to sacrifice comfort for all out speed - will always be faster.
