RWHP Numbers
Just a few questions regarding the horsepower of these cars. I know the LS1 responds very well to bolt-ons, intake, headers, tune, ect. So what does a stock one dyno at and what are some realistic numbers after some work? Also supercharging, I have tons of experience with as my DD is a supercharged truck with 14lbs lol, but what is safe on a stock LS1 and what kinda numbers can one see reliably? Thanks again guys.....

My 405hp LS6 thru a stalled A4 and 3.15 rear, with honker, 25% underdrive pulley, LG Pros w/ barely cats, and a tune made 366 rwhp. After A&A Si trim supercharger install and removal of honker and underdrive pulley, it made just over 540rwhp on about 7lbs of boost. Most will say that with a good tune 7-10 lbs is safe on a stock bottom end without methanol injection, though some run more.

Mine was 323 RWHP with Bolt Ons - LS1, A4, 3.15 gears, CAI (All the Bolt Ons)
Went to 585 RWHP with Headers, H/C and SuperCharger - now I have 701 RWHP with other upgrades to the gears and tranny (See sig below)
90,000 miles on the stock A4, it finally let go after it overheated
Thanks,Matt

Safe depends on primarily the tune of the car. If the person who tunes it is good and knows what they are doing, you have safely have over 600 RWHP or even almost 700. Mt camaro that is procharged (stock LS1 minus cam,exhaust and rod bolts) made 601 to the tire on 10 PSI. My vette that is also Procharged on 10 PSI also stock minus cam and exhaust made a little over 685.

The numbers you might get after some mods will vary depending on just what you do - a good head/cam job might get you 40-50 rwhp, LT headers maybe 15-20 rwhp, etc.

Get the rwhp over 400 and you can have lots of fun, how you get there is your choice, FI for a quick setup
or cam and heads for old school hp if you like some lump at idle, either way will put a
on your face.

I think bone stock, an LS1 will put down between 295 - 310 RWHP in C5 trim. With a good combination of quality bolt ons i.e. CAI, TB, intake mainfold, H/C, LTs, cat back exhaust and a good tune, you can achieve 500 RWHP on a normally aspirated car. I know others will say more. It all depends on how agressive one gets with some of these mods. With supercharging, I think the sky is the limit depdending on how you set things up. I see supercharged cars on here all the time with 450 - 800 RWHP. Getting that power to the ground is the real trick. Much over 500RWHP and you better be thinking of upgrading other drive line compenents and the bottom end.
