How much rwhp is possible on a bolt on only M6 LS1?? I say 380-390.. I know dynos don't mean squat to figure out who is fastest, but I set a little goal for myself to get close to 380-390rwhp with just bolt ons...
I'm wondering if anyone else has reasoning as to why this would be unobtainable.
As of a month ago, I dynoed 357rwhp with a steel driveshaft and 4.10 gears/stock 10 bolt in the car.
Since then I have installed a carbon fiber driveshaft, and changed my gear ratio to 3.73, but using a 12 bolt/33 spline rear end instead of my old stock 10 bolt.
I figure the new taller gears and the heavier rear end will cancel one another out...but the driveshaft should give maybe 8rwhp since I had a steel one in its place.
I could be up to 365rwhp right now.
I figure I will get an aluminum flywheel and eradispeed rotors which will lighten the rotating mass up even more for about 10rwhp or so which could leave me at 375rwhp....
All that is left is a ported TB, and some more tuning, and I think I have 5rwhp or so left from tuning...so I'm thinking 382rwhp??? give or take a few????
DOABLE??? What do you guys think?? <img src="images/icons/confused.gif" border="0">

Re: How much rwhp is possible on a bolt on only M6 LS1?? I say 380-390.. If it is possible it would be very hard to obtain. I would say you would have to have:
EVERY bolt on
NO catback
CF driveshaft
aluminum flywheel
stock rear with 2.73's
lightweight brake setup
draglites
very light tires aired up to 50 psi
bag of ice on the intake
Then maybe you might get the rwhp you are looking for <img src="gr_grin.gif" border="0">

Re: How much rwhp is possible on a bolt on only M6 LS1?? I say 380-390.. Is your 357 RWHP SAE corrected? If so, I would like to see a copy of your dyno sheet. I haven't seen anyone in the 350's with just boltons in my life expecially with 373's and a steel driveshaft. That sounds like uncorrected or standard numbers to me.
Please post a link to your dyno sheet.

Not doable. You are using ricer math. Use domestic math you'll hit 360 something if you are lucky with all that, unless I'm drastically understimating the gains possible on a near stock car with tuning. The aluminum flywheel will show 2hp on the dyno if you are lucky, the carbon fiber driveshaft maybe 3. These items dont help much in 4th gear (dyno gear) since you dont have to accelerate them as quickly as you might in 1st gear.
Good luck. I'll be impressed if you hit 365 with all that stuff you listed, SAE corrected.

Re: How much rwhp is possible on a bolt on only M6 LS1?? I say 380-390.. With a cam and most of the mods you have I am at 360rwhp and 355 rwtq....thats with a pretty aggressive cam....And I made that at 6300....the highest I have EVER seen with bolt ons is in the 340's....

I made 402 rwhp SAE corrected on a dynojet with boltons and a B1 cam, 360 rwhp is actually low for a cam only car (I was on the upper end of the cam only cars).
I second jmX, you dont just add up what you think you will get. The 12 bolt with 3.73s has more reciprocating mass than a 10 bolt with 4.10s so you will prolly lose a handful of hp, and 8 rwhp from a driveshaft swap is unrealistic imo. Why dont you just spend the money on a nice cam and gain 35+ rwhp rather than *****-footing around with minor bolt-ons and dyno tricks?

Re: How much rwhp is possible on a bolt on only M6 LS1?? I say 380-390.. I don't know if you can get 380. But here is my dyno chart with the mods in the sig. http://www.evilface.com/cofba/dyno/jasonp.jpg I think you can get pretty close but not 380 maybe in the low 370's.

I think I might be able to do 355 SAE with a pulley. See my dyno chart above. I am stock 3.42 gears and alluminum driveshaft though.

Re: How much rwhp is possible on a bolt on only M6 LS1?? I say 380-390.. What's up Verbs? I think 380rwhp might be tough but you never know. I dynoed 346rwhp and 360rwtq with bolt just on's and no headers, pullies or programing. I think some Mac's and B1 or T1 cam will get me to the 380 mark but we will see. Good luck Matt.

Re: How much rwhp is possible on a bolt on only M6 LS1?? I say 380-390.. I'd be impressed if you hit 350rwhp. I do not think you'll make 360. Either way its a waste of time. Get a cam.

Re: How much rwhp is possible on a bolt on only M6 LS1?? I say 380-390.. Ok guys i have dynoed the car twice on Dynojets, I have made 365 rwhp and 371 rwtq on one dyno and 371 rwhp and 385 rwtq. So the dynos do vary a bit but the hp is still there. Mods and times are in the sig i also have the highest mph for a stock motored 6 speed car. And i also have the stock 3.42s

Re: How much rwhp is possible on a bolt on only M6 LS1?? I say 380-390.. Not do able, and whats the point? your car wont make that power on the street, why not say you have 350rwhp and win races then claim 380 and loose? LOL When on the street hot, w/ exhaust, and real gears, you're no longer a dyno queen, and dynos dont mean jack, I understand the goal, but I only think its worthwhile if it is going to be as the car would be on the street, for example backing it strait on the dyno off the street..
fwiw my car did 354/365 w/ just bolt-ons..

Re: How much rwhp is possible on a bolt on only M6 LS1?? I say 380-390.. I don't mean to sound like a negative ******* here but you will not get 390 rwhp out of a bolt on car. Plain and simple. Limitations of the stock cam+stock heads are going to hit you at some point. The stock LS1 motor is giving you a foot, and you're trying to take a mile.
If you want that kind of power, stop wasting your time trying to do dyno tricks, and all that other crap. Spend some money and time on real mods and you'll easily see that power.

Re: How much rwhp is possible on a bolt on only M6 LS1?? I say 380-390.. Well i have never seen so many 375 rwhp cars in my life. Seeing as i have heads, cam, long tube headers, and alot of bolt ons then i should see about 425 rwhp, but i doubt it. I will be lucky to get 385 rwhp with my setup. I sure would like to dyno my car in another state to see what it does. <img src="graemlins/gr_hail.gif" border="0" alt="[hail]" />

BTW, the dyno was with 4.10 gears and a steel driveshaft, not 3.73's. I just recently installed 3.73's w/ my new 12 bolt. The dyno was months ago.
On that thread there is a link to my dyno sheet towards the bottom. Same screen name. The correction factor used was 1.02, and the dyno results were before and after an adjustable fuel pressure regulator was added on the car.

Re: How much rwhp is possible on a bolt on only M6 LS1?? I say 380-390.. Keep in mind this post is not about being a dyno queen. I just think everyone sets this standard limit on bolt on dynos of 350rwhp. 2 other people have chimed in with 350+rwhp and someone earlier said it wasn't doable and they haven't seen anyone do it.
The 380-390 rwhp thing is something I think is obtainable theoretically with stock gear gearing, a 10 bolt, and every mod in the book.
I'd like to get close to that figure in theory, but I'm just wondering how far I can get given the mods I haven't done yet. And I'm not gonna touch the engine till the warranty is up. Plain and simple.
