Is there anyway I can beat a LT1 that is pushing 500hp?

[geoffinbc]

If this guy is smart at all he will be able to make himself a proper weight transfering suspension. He will be able to get traction. Some guy that races a white 96 S-10 up here has a great suspension and his front tires lift on launch. I'm sure he has done alot to get more weight in the back. Fuell cell, battery, etc...

[BlackJack]

here's to hoping he's not that smart

[geoffinbc]

Oh and a 500HP LT1 isn't an easy or cheep thing to produce. So this guy has high hopes or alot of money.

Isnt there usually nothing but a bunch of shit talk from muscle car guys? My favorite is how much power the cars came out of the factory with back when my dad was a kid. But he never takes the explaination that they measure power on the dyno differently now. So 220 now = 400 for my dad.

He's never liked that.

Even if it's not 500hp. I'd still think he'd have some trouble running a 3400 Sunfire (heavier and hence slower than 2nd Gen with the same motor) up against a decently built LT1.

Yea back in the day car makers would lie in order to make insurance costs on their vehicles cheeper. They would put out a horsepower figure but it would be at 3000~4000RPM and not the rating of the actual peak horsepower. Which for some solid lifter engines of the day was well into the 5000RPM range. Some smallblock packages of the day would easily wind into the high 6000RPM range.

just unhook his driveshaft before you race

WTH are you talking about?

Horsepower has always been measured the same way.

I bet most of those cars you are saying have very little power actually put out more than they are rated, strapped to todays dynos.

He is refering too "gross" vs "Net" HP measurements. I found this...

NET HP VS GROSS HP:
Contrary to what many will tell you, Gross and Net Power are BOTH measured at the flywheel! Gross is atmospherically corrected to dry air, 59 F, and sea level; Net is corrected to 32% humidity, 77 F, sea level. There's a 3% difference right there in power quotes. Many people argue that there's no place on earth with totally dry air at sea level so I applaud the Net correction made in 1972. If your dyno tests were done at elevation and temps other than this, then they need to be corrected to NET conditions. Check to see if the dyno shop already has done so and see what conditions they correct to. Everyone likes big numbers, so lots of 59 degree days are still used.

The biggest difference between Net and Gross is the accessories that are omitted for Gross testing. Net is measured with full exhaust system, full intake system, v-belts on, mechanical fan on, all accessories installed but not operating (ie a/c). We should all compare Net power because it provides direct comparison with all production vehicles since 1972. The Gross stuff in pre '72 generally is around 25% higher but that number really varies... it depends heavily on the test engineer's methods; some would leave on the fan and water pump, others would remove them and use an electric motor, some would use stock cast iron manifolds, some would use open headers, etc.. Most everyone would run very good gas and tweak the distributor at each rpm point to find a max - even though that might not represent the factory ignition curve. You get the picture.

Cars were measure in Gross HP back in teh muscle car era. Despite this they were still under rated big time. Sometimes by a couple hundred hourses in the case of the L88 Corvette

[Doubt_Incarnate]

yeah i thought i saw on history channel or speedvision the gto judge ram air v or something was actually 525 hp. i think both jegs and summit offer an lt4 upgrade package for the lt1 that supposedly puts out like 405hp. if thats true, add in a real exhaust system and tuning and maybe he gets close enough to 500 for him to think he actually has it. the thing for him is he is rwd, so when/if he hooks up he's gonna go, and not to mention the seemingly endless aftermarket for his platform.

Re: Is there anyway I can beat a LT1 that is pushing 500hp?

Hi Guys
I am just wondering if I can beat a LT1 that is pushing 500hp? bc right now I got a not complete 3400 motor that is factory build and i am just wondering if there is anyway i can keep up or beat my assistant manager 96 s-10 LT-1? bc my assistant manager is saying there noway i can beat him with my 3400 motor in my sunfire and i would like to show it to him i can beat him with my 3400.

Bracket race........

[geoffinbc]

HA HA thats about it too. But its still considered a win!

[SHOoff]

If you look at the title to this thread. I think the proper answer is.....

"If he actually does have that much power. Not an ice cube's chance in hell"

[Syn]

do 3 races and have him give you 8 cars, if you lose all 3 run like hell so you don't have to handover the keys

[BlackJack]

sorry, took me a minute to get caught up....some of this is old by now.

My heavier Jimmy with half the power. street radials, and no traction would own you. Now that I have some traction, some decent tires and will have more power, I should be able to hang with that S-10 you are going to get owned by.
SIGTAG:James: 1985 GMC Jimmy, 3.2L turbocharged, intercooled hybrid 13.873 @ 99.08 218HP & 270FT/lbs @ the rear wheels

^if that's the Jimmy you're talking about in your sig, those numbers dont exactly say "own you". I know mildly built turbo 3400 cars that run faster times and trap speeds.

shall the list go on?

Horsepower has always been measured the same way. Rolling Eyes

But to point out to the contrary, Dynojet and Mustang dynos both dont give the same HP rating, maybe I didn't understand you correctly though.
