new motor time lt1 vette or 5.3 truck? - Page 2 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

FirstGen · 04-21-2005, 09:48 PM

410 with a cam and exhaust is high but I've seen it happen. It's just not the norm. Anywhere from 290-310 is common stock and 315+ range are freaks which do exist and have seen several of them (maybe 10 out of 100). Honestly when you start making 400+ rear wheel horse, you prolly won't see any noticable gain maybe 3 or 4 hp with the addition of an underdrive pulley - maybe nothing. Just remember the more power you make the less stuff like that matters. To see 10 rwhp with an ASP on a stock motor is one thing but it almost never happens on a car making good power already. Something to think about.
Let me know what you dyno on your '02. I've seen and personally dynoed hundreds of these cars so it shouldn't be any surprise when you make between 295-315 alot depends on if its a A4 or M6 car...

gmc67swb,

That is what I like to here. The 01-02 LS1 came from the factory with the LS6 intakes.

NPilot1975 · 04-22-2005, 05:39 AM

FirstGen,

What do you do for a living? Are most of the cars that you dyno Camaros/TA's?

I am pretty sure that a '01 SS Camaro is factory rated at 315 hp, exactly what gmc67swb said it pulled on the dyno stock.

NPilot1975 · 04-22-2005, 05:44 AM

Nathank,

Here is the link for the adapter plates.

http://cgi.ebay.com/ebaymotors/ws/eB...category=50454

They are set up for the 3-bolt stock 67-72 V-8 motor mounts.

FirstGen · 04-22-2005, 08:16 AM

I use to be a tuner for The Horsepower Store. Yes the 01-02 cars have LS6 intakes and no EGR stuff. They are rated at 320 but this is flywheel not rear wheel. Actually there is no difference in the camaro and the vette. The Z06 vette is quite different because of it's LS6 heads and a better cam/springs. In fact your 01 vette has the identical cam the camaro does... All F and Y bodies have the same cam along with the 6.0 liter truck motors for 2001-2003.

Mine is an M6. If i'm not mistaken the '98-00 camaros had bigger cams compared to the '01-02 cars. All I can say is thank you GM for building a motor that will damn near put down what they rate it at at the flywheel to the wheels.

Actually the 01-02 f-bodies had larger cams...

Firstgen,
We go to Kennedale quiet often on Thursdays. You should bring the truck out there some time. I would like to see it . My buddy's car runs 6.9xxs. Mine on the other hand only has run 9.0's. I still have the orignal Goodyears on the car and it actually roasts the tires in 2nd. It's kinda frustrating. I need tires bad. I think it should run like 8.6xs. I'm trapping 84 mph so I know there's alot to be had. My '98 SS ran 8.8's at 81mph with street tires and no mods.

The 400rwhp is pretty normal for a full bolt on cam only car. Just look around on Ls2.com or LS1tech.com and you'll see. Granted the cam is gonna be nasty(.600+ lift) but the guys are doing it on a regular basis. My buddy's car is his daily driver also. I've seen heads and cam cars put down 450rwhp. Just a little fuel for thought. They've come along way with the cams since the intro of the LS in '97.

I hear what you are saying but I've personally seen different. You might hear of people claiming 400 rwhp cam only bolt on cars, but it's an exception not a rule. Typically a cam only car will make around 385 rwhp. Cars making 450 heads/cam are very uncommon. That would be the ideal and max you will ever see. Typically AFR headed stock cube LS1's make around 440. Just FYI, get some dynograph from people off LS1Tech and you might be surprised.

Hey you guys..... Redline Raceway in Greenville is having their 1st of the season King Of The Hill shootout tonight. It's brings in some decent rides from all over. Big engines.... bigger power adders..... & limited tire size. Definitely a recipie for fun.

I'm going out there & thought I would extend an invite to others in this area who are interested in similar stuff. Gates open @ 6pm. Qualifying starts @ 7. $15 bucks entry (race or spectate). Canned beverages only.

Are you sure?

I witnessed the H/C car put down 450rwhp. I also witnessed the cam only car put down 410rwhp. Both on the same day! Fastech is having a dyno day on May 7. It will interesting to see what people bring out to dyno.

FirstGen · 04-23-2005, 06:07 PM

sweet. well even if they have a minutly smaller cam the 01-02 cars make more power with out the EGR and with the LS6 intake...

like I said 450 rwhp can be done, it's just not common place. also alot of places like with Sean at Fastech (rip off) they will and have mipulated the dyno print outs to reflect uncorrected horsepower numbers when it benifits them. My truck made 488 rwhp UNCORRECTED but 452 SAE. SAE is the standard and thats what I go by. I really don't feel like discussing this topic any further. We have a difference of opinion by all of 10-20 rwhp. I have personally/physically dynoed 100's of f-bodies but I probably don't know what I'm talking about... All in good fun,
Taylor

gmc67swb · 04-23-2005, 06:14 PM

I'm sure you know what your talking about aside from the cams. But like you said a difference in opinions.

Good Day sir,

Larry

gmc67swb · 04-27-2005, 05:12 PM

Here are the #'s for the sake of discussion. My car did 303rwhp/325rwt. This car was COMPLETELY stock. After longtube headers and underdrive pulley.....335rwhp and 350rwt. I am very pleased. These are the only to additions to the car. Stock lid/air filter, stock cat back and stock TB. Car is still extremely quiet.

Never argued that fact...Just telling you what I've seen before. Just wanted to post the #'s for everyone to see first hand and so they could get an idea of what to expect

Right on, thanks! Why don't you post the graphs also that would be cool.

This is my graph N/A. Mods: 6.0 LS1 LQ4 (stock 9.4:1 CR), milled heads .030, ASP underdrive pulley, home ported MAC mid-length headers, dual 3" exhaust with magnaflows, custom grind comp cam 232/238 595/605 112+2, comp 918 springs, comp Ti retainers, home ported TB, custom mandrel 4" intake, de-screened MAF, K&N filter, LS1 factory E-fans, 8.1L injectors, SPEC 3 clutch, T56 tranny, Steel driveshaft with all 1350 forged yokes, 12 bolt rear, 4:11 ratio with Eaton posi, 305/45/18 drag radials, tuned by me with LS1Edit/AutoTAP.

NPilot1975 · 04-28-2005, 12:56 AM

FirstGen-

Do you have a dyno run for a completely stock Silverado or Escalade with a 6.0L engine in it?

FirstGen · 04-28-2005, 09:00 AM

No I don't, they usually put down in the 300 rwhp range. They have alot of driveline loss because of the 4L80e trans and most of them have a t-case for four wheel drive application. Most of the Silverado SS trucks make around 300-330 rwhp with the front shaft dis-connected.
