My 99 T/A is all stock at the moment, but in a few weeks ill be putting on kooks LTs,y pipe ,borla catback and a slp, i have everything already except the borla i just have to pay a few bills this week then everythings a go. My goal is to build it up to around 600-700whp,keep it naturally aspirated, without having to tear the engine down an put all new internals, is reaching numbers like that even possible with what im asking?


In the future i wanna slowly build up a LS7 with all forged internals and all the bells an whistles, an swap the LS1 out, in the meantime im just tryna have some fun with the LS1.

i figure once i get the exhaust done, upgrade the intake, do heads & a cam i should be around the 400-5XX range, where do i go from there?

700whp on a stock bottom end? I doubt it. But im still new to this. A hefty shot a nitrous should probobly help as well

Gotta go bigger cubes lsx with a giant cam and good flowing heads. Most i've seen an ls1 put out was in a ballpark of 500 rwhp... dont expect it to be a tame dd after that

You want 600-700rwhp out of a stock 346 ls1 shortblock? Not a chance in the world.......Even 500rwhp on the dot were talking high compression max effort big money heads/cam/intake setup. If you want 600+rwhp n/a you need 400+c.i. at the very least.

Yep. Pretty much what he said.

Without boost u will not see those numbers on as ls1,

Even with boost thats pushing a stock block pretty hard,never shoot for hp numbers time slips will build you a much faster car,

I agree he needs to look into another motor. But **** he can spray a 346 into 600rwhp. He doesn't have to go FI.

Build the car from the ground up, didn't mention if it was an M6 or A4. Nitrous would be the cheapest route but the trans and rear won't hold on for long. As stated above 700 to the tire isn't going to happen N/A with stock cubes.

This is how feelings get hurt after a build is complete.

Want 700+?
Forged, Forced induction, Big cubes.
Pick 2..or 3

I'm not sure if you're just making guesses at the kind of gains you'll get from mods or if you're extremely misinformed.

Those expecatations aren't realistic. A streetable heads, cam, intake + full bolt on setup will get you anywhere from 440-460 rwhp on a stock cube LS1. There are some other "max effort" setups that have made it to the 500 rwhp mark, however that isn't the norm.

If you're interested in a dyno number, a solid heads, cam, intake and bolt on setup plus a 150 shot of N2O might get you a dyno pull in the 600 rwhp range, however don't expect the stock bottom end to hold onto that for too long (personal experience).

In view of this, I would urge you to consider your goals and your budget without putting any type of power numbers criteria. At the end of the day, who cares about the numbers if the car meets your goals and budget constraints.

Thanks for all the responses, but yea i figured it wasnt too realistic lol just tryna see how close i could get to that mark without going FI. I forgot to add im not trying to go nitrous either.

I think ill just have some fun with the LS1 right now and build the transmission an rear end, throwing in a bigger block ill have to anyway. And just save my $ for a LS7 build.

The car is a A4, and its my daily driver at the moment, but im planning on getting a honda or acura beater for work to keep the miles off the TA.

A4 - get a 4L80E and 12 bolt rear and you will be good to go when you slap in the bigger motor.

Whiplash88

yea thats what i was planning on doing.

Just wondering, what kind of #s (ballpark) will i be looking at with going supercharged at low boost?

Roarin_8

Probably 550rwhp at low boost.

this is one of the worst questions ive seen asked on here in a while

your gonna need 15-20k for something ls na with that much hp .

FoHawk

550rwhp are what LS3's are getting at low boost, he's looking more around 475rwhp at low boost, depending on supporting mods of course.

I'm going by numbers from a Procharger at 8lbs of boost:

98-02 - 8+ psi w/ D-1SC 60%+ Twin Highflow intercooler

60 percent increase over say 350rwhp will equal around 560rwhp.
