Just wondering what you guys think.

[nastyNater]

Some old guy in a 5.0 wants to race me. He says hes got an '86 stock 5.0 and that if he beats me by three lengths or more I give him $300. WTH? why would you ever do this. Well i was w/ my brother and he was driving since i dont want a DUI, and the guy was like allright man Im gonna go get my car. This dude was cracked out seriously. Well he never came back. Im going to go find him today. Dam I want some easy money. If I can pull a '02 stock GT then a 5.0 should be nothing right?

WRONG question to ask....they are gonna eat you alive. Note for future reference do not under any circumstances bench race. You are gonna get flamed hard. BUT just race and find out.

[nastyNater]

HA. i just talked to my brother. he just raced the guy. best 2/3 from a 40mph pull. The integra won the first two by what my brother said was more than 5 lengths. too bad i wasnt there. we split the $300.
.....that guy is an idiot

[nastyNater]

my brother said that when he got to the guys house the guy wanted to race his GSX-R intstead of his 5.0....haha

Im curious what kind of cams are you running? and what ecu?

[Shpyder]

It's all about when your car reaches its peak RPM. That's how a 200 lb/ft car can dust a 400 lb/ft car on the track. We've all seen it before.

Horsepower = [Torque x RPM]/5252

a 200 lb/ft car that shifts at 8500 RPM has 323 HP.

a 400 lb/ft car that shifts at 4000 RPM has 304 HP.

The car with less torque will trap a high ET. That's an exaggerated example, but you get the point. When you shift, your wheel torque is sliced in half. You want to push your peak torque further along the curve. That's why Formula 1 cars are so insanely quick...they have 1L engine but reach peak torque at 18000 RPM.

sorry, you probably didnt need a physics lesson but I just wanted to sound smart for a change

I would race him, forget the money for now. Throw in a good launch and you should be fine.

[nastyNater]

im running obd1 p72....my friend tuned it.
i got a set of crower cams-63402a's...Int-297 dur. / 11.8mm lift
Exh-287 dur. / 11.8mm lift
i like em allright since my car still idles nice.

[nastyNater]

my brother already raced him...his money is ours

champ cars only have 1L of displacement? i didnt know that

Some teams use up to 3Ls.

so there are cars running 1L vs 3L? what are the restrictions....how do they keep the field even?

[Shpyder]

There are regulations that restrict maximum engine size to 3.0 litres, and all cars must have ten cylinders, with a maximum of 5 valves per cyl. No forced induction is allowed. It is up to the indvidual teams to see what kind of engine/car they can come up with within 3.0 litres. Displacement can vary per car, and we know how bigger isnt always faster...

[nastyNater]

yeah it just seems like you would use the displacement to your advantage. espiecially when the stakes are so high. i cant understand that if you could have all the same mods on your 1L as the 3.0 that you wouldnt use the larger displacing engine.

thats so crazy that a tiny little 10 cylinder can put out those insane revs. I knew that they redlined in the teens but i had no idea that they were all N/A and that they were 10's. I have always thought they were V6's.

[ryanisfast]

yeah, but those racecars have big bores and very short strokes.

Absolutely. The short stroke makes the engine more stable at the insane RPMs those cars put out. Short stroke = less distance travelled by the piston = less chance for the rod/piston mechanism to come lose or lose its way of travel = high revs.
