Depends where you race (track prep, DA, etc)

I have bolt-ons only (3800 stall, QTP headers and ORY-pipe, LSX intake, MTI ported TB, lid/filter, ASP pulley, cutout, 3.73 gears) and ran a best of 11.75 @ 115 (@ Maryland International Raceway) with two other 11.7 runs, and a 11.8.

My car ran a 12.9 with a lid, SFC's, and drag radials. So yeah, whoever is saying anywhere NEAR the 13's is either racing in Denver or is smoking the pipe. I say high 11s to low 12s if you can manage a 1.5x 60' (gonna be tricky with DRs)

Only way to know is get your *** out there and try it! Good luck

 

For suspension, start off with subframe connectors, lower control arms, and relocation brackets. Maybe a panhard rod to help stay straight. That and some good drag radials will be most all of the traction you need for a bolt on car

 

Before you even think about modding the car with horsepower mods and taking it to the dragstrip, I suggest you start off with what I call Dragstrip-Prep Mods, or mods that won't make your car any quicker or faster, but they'll protect what already came on the car from the factory. I'm talking about subframe connectors to keep your subframes straight and to minimize quarter-panel dimples, rear-end girdle to strenghten your rear end, an automatic transmission cooler to keep your transmission temperatures down, and (most importantly) proper maintenance.

As far as your list of mods go, you'll probably get significantly more gains with a much better exhaust system. In ls1tech.com, I've read about people that went from the factory exhaust to a completely upgraded exhaust system that consisted of Kooks longtubes, y-pipe with hi flo cats, and a catback. Along with a dyno-tune, these same people have actually achieved a 50 rwhp increase!

As far as your induction mods go, I've heard that you will want to stay away from even touching the MAF, because any modifications to it might make it really hard for your tuner to tune the car. Also, other induction mods such as an underhood cold air induction, lid, and ported throttle body might not show up as a gain on the dyno since you won't have a high-velocity fan blowing air into the car during a dyno-run. I've read that those bolt-on induction mods are significant on the dragtrip and you'll get more horsepower out of them than what some people above me have said.

I would say, at best, you can get between 50 and 60 rwhp with just the horsepower mods that I recommended above. As for the quarter mile, I would say mid to high 12's at 110 MPH.

 

mid to high 12

you do realize that a few guys were able to pull high 12s bone stock with sticky tires right??

not saying all LS1s are able to do that...but most are low 13s driven well.

a FULL bolt on car should be able to nearly hit 11s

 

I know. I've also seen a timeslip where an '01 WS6 A4 pulled a 1.9xx 60' and got 12.9x@107-108 MPH completely bone-stock on stock tires set at 30 psi. It's better to expect the worse or the average than to expect the best possible timeslips.

 

A local guy around here went Internally Stock: 11.76 @ 114.53 MPH w/ 1.60 sixty foot

 

Well I have just about all you can bolt on with only 328hp+ 344 torque at the wheels.

 

i never truly understood the bolt on thing. technically, dont you bolt on a s/c? bolt down a nos bottle?

 

Did you get a dyno-tune? If you have an A4, then was your dyno locked or unlocked? A ported throttle body is another good bolt-on.

 

yeah no kidding.

wasn't it Keliente that dynoed 42hp gain from headers, ls6 intake and a dyno tune?

but there is also mods like true duals for a little more peak power, even over the LM. not to mention the electric waterpump.

 

That was a dyno-tune it's a M6 we didn't realize it at the time but the car was misfiring they thought I had an after market cam the way the car was idling. I’m thinking maybe that throw the dyno off a bit.

 

geez...why did you even bother posting the numbers than

that's kindda like comparing 3 mile cross country times from an olymian who has branchitis

 

Thanks for the advice.

 

well...

if you knew the car was running like ****...why would you volunteer the dyno number for someone looking to see how much bolt on cars can make.

 

I thought the role of a supporting member was to offer advise not insult fellow members. If you can't take a hint by now I'm a novice to Automobile mechanics other than changing my own engine oil. You might consider using logic before just assuming like an F---ing idiot.
