I find that funny. All you ever post about is DYNO #'s. I don't think I ever recall you posting anything about running your car at the track.

Surely you don't think that a dealer is going to work on your car when you pull in with a set of longtubes, true dual exhaust, aluminum flywheel, carbon fiber BS, pullies, all the free mods, ported or aftermarket TB, lid, catback/cutout, and I could keep this list going. After all, you did say "every mod in the book". You are terribly mistaken if you think a GM rep is going to approve work on your car with those type of mods.

Ouch!!! Take it easy. I know verbs and he's a cool guy. I don't think he is trying to be dyno queen he was just asking for some of your opinions. As far as track times i think he runs mid 12's at 108-110mph in AZ heat and 2500ft evl. <img src="graemlins/camaro.gif" border="0" alt="[Chevrolet]" />

What is your elevation? I seem to remember something about higher elevation dynos giving higher than normal "corrected" numbers. I could be wrong though.

The most I've seen with a bolt-on car is about 355 rwhp, the biggest limiting factor that you have now is your stock cam. I've seen cars with bolt-ons and an aftermarket cam make in the 380-390 rwhp range - about what your looking for.

So do I. A cam isnt going to void your warranty, and neither are heads as long as you keep your exhaust capped up. What are they gonna do, pull out your cam and run it through a cam doctor? PK is right, I love putting 15+ lengths on a fellow LS1 on the street and telling them my only mod is my muffler fell off <img src="gr_images/icons/cool.gif" border="0">

Phoenix is at 12-1300 foot elevation.
If that dyno was done at Pro Dyno I've always thought their dyno was a little optimistic. Not saying you didn't dyno what you say but I've seen quite a few really good dynos from there - including my own. I dyno'd at 323 rwhp with nothing but a Mecham exhaust and only 700 miles on my '98 WS6.
Also, if they are the guys who put on the regulator (I think they did) I'd bet that the regulator delivered exactly what they said it would. Same thing happened on my Mecham exhaust. They said 17 rwhp with that exhaust and before and after dynos [i]confirmed[i] exactly that gain <img src="gr_grin.gif" border="0">
Again, I'm not trying to slam you or Pro Dyno.

Actually you are terribly mistaken. The GM dealership that I use has no problems with my car the way it is....as long as I don't touch the engine. Every warranty issue I've had has been taken care of. In fact, they just replaced the piston rings and fixed my synchros....FOR FREE.

Verbs,

We dynoed a 2000 Z28 car at the end of last year to support an upcoming tech article. It had the typical bolt-ons plus some other neat stuff. I don't remember the exact number, but it had over 450 BHP (assuming a 15.5% drivetrain loss). I witnessed most of the testing. To test the accuracy of the dyno, another car was tested whose HP was known. The dyno checked out fine.

An upper level GM representative was on hand and actually drove the car on the street with the owner onboard. After the test drive the GM rep popped the hood, jumped out of car and checked for nitrous lines. The GM rep couldn't find any nitrous lines and proceded to ask the owner about all that was done to the car.

I guess to answer your original question - yes, I personally saw over 380 RWHP from a bolt-on car.

I can't wait to put slicks on my 12 bolt so I can shoot for hi 11's.

I have no traction even w/ DR's on and could never cut better than a 1.9-2.0 60ft....

It's not easy to cap a true dual exhaust w/ no cats either.....I wish it was that simple.

12.6 sounds about right for about 350 rwhp.
BTW, Speedworld is 1250 foot and Firebird is 1320.

LMAO, Yall are as ignorant as they come if you think a bolton LS1 will make and has made that much power, there are limitations as hard as that may be to believe, thats like saying a rare heads/cam car can make 500+ rwhp, LOL...Tell you what, you go dyno 380rwhp w/ bolton car and I guarentee you my 354rwhp bolton car will drag the **** out of it <img src="gr_images/icons/wink.gif" border="0"> Be realistic and get some real mods then talk about dyno numbers when you are in fact tuning a car and testing out new combos..btw, my heads/cam car never had a problem w/ warranty work, new rearend, t56, the list goes on my friends.. <img src="gr_images/icons/wink.gif" border="0">

12.6 sounds right for 350rwhp?
My last dyno was 337 rwhp.

Sorry, I left a 1 out. I meant to say that 112.6 mph sounds about right for 350 rwhp. I based that off of me running 109 mph at 323 rwhp. Your milage may vary <img src="gr_stretch.gif" border="0">

I dynoed 350 with 4.10s, stock driveshaft, heavy SS wheels. Now I dyno ~340 with a 12 bolt, Denny's Drive shaft, Cartek clutch, still SS wheels (just got Fikses). I say with a CF driveshaft, lightweight flwheel, 10 bolt with 3.42s, and Draglites I would easily be above 360. But I'd rather run 10s <img src="graemlins/gr_devil.gif" border="0" alt="[devil]" /> (coming soon hopefully).

I really hate warranty queens. NOTHING makes me happier than to see their warranty claims denied because of long tube headers, a maf, or some other little mod they never thought would void the warranty.

Regarding the bolt on HP, who cares? I'm sure I could "fix" the dyno to make a stock engine car produce over 400rwhp, does it mean anything? Getting back to your theory, the 12 bolt is going to cost you 10rwhp or so, the flywheel and CF driveshaft will be worth about 5rwhp, and the ported TB will be worth another 3-4rwhp. So if you dyno 360 now I'd guess you'll be around the same with all those mods.

I think we all agree a car with a cam and bolt on's can dyno 380+rwhp or better with good tuning.

The trick is getting 380+rwhp out of the same set up WITHOUT a cam swap. 1.9 Roller Rockers sure would add more lift to the stock cam. These 1.9 RR's would increase the lift of the stock cam from about .500 to about .550

I think the 1.9's would make the stock cam act bigger. Since the engine isn't cracked open technically it's a bolt on.

As to the reason, if he want's to try nothing wrong with it. He should know straight up it's not the best gain for the money he is spending. However, it would be intresting to see.

I think the stock 10 bolt with 3.42 will need to go back in. Might want to ask Jay Fisher and friends about their electrical water pump because you'll need every hp you can get. Also Phoenix has a new induction kit coming out they claim is worth several rwhp over the best lid.

As to warranty, my dealer told me LT were fine but don't crack the engine open with a cam or top end package. My cars been in many times for warranty work with mod's listed below. Dick Keffer always said they didn't care as long as the motor wasn't cracked open and honored their word.

I also know of one case (not at Keffer) where a LS1 with a heads and cam package had cam walk and the engine wiped out. Dealer had replaced the cam sensor etc but didn't realize the sensor was ok but the cam was walking. GM replaced the engine under warranty and it had been cracked open. The word was the car had a cam walk problem before the heads and cam but...well sometimes you never know. Sometimes GM will try to screw you on warranty over small things and sometimes GM screws itself on warranty over major things.

You pay your money and you take your chances.

Personally, if my bolt car made 350rwhp I'd go for a cam and forget about tweaking a bolt on's.
