celica gt-s 16s? it must be what year you're talkin about. my neighbor has a 2001 and it runs 14.8 stock @ the great lakes dragstrip. i kno that megan racing products are crap, but what bout OBX, ive heard their crap too, the hearders crack. what other companies should he stay away from if you kno of any.

I said a 15.6 average. AVERAGE!! plus I don't believe you

I've seen a spec run a 14.9 at the track with intake exhaust AND a passenger so it's definantley all driver.

celica gts is slower than a spec dude, maybe the driver was like warren johnson or something but ive never seen a stock gts run fatser than a spec

fugiot · #20 09-22-2005, 03:29 AM

who said it was faster?

I have a friend with a specV he runs on average 14.5 with very little mods, and thats in hot/humid/shitty track conditions with stock tires. (dont know the mods exactly but I'll find out if you ask.)

but like all of you are saying, driver skill is a big difference, I'll admit Im not a very good driver. On average I get 14.5's out of my civic, I let my friend with the specV drive and he gets 14.3's. At the same 95mph which hints that the .2 was all driver

(yeah, I suck). Actually I dont suck, he just happens to be a very good driver. A big group of friends let him drive their cars to see better times out of their cars!

idk, i guess its all driver, he's not a warren johnson o n e thing, but all he had was a CAI when he made the run to my knowlege. i dont wanna start getting flamed on..geez.... i dont think a CAI would really make the car be that much faster, maybe like .1 or .2.....

Well, it also depends on the mods. My Classic SE-R has 3 mods and dropped the 1/4 time by 1.1 seconds. There's a lot more to racing modified cars than the actual racing. You have to know your engine and what mods will get you the best results for your money.

oic, that means research on your engine a lot, unless u kno it really well. i thought that u gained a lot more power if u could bring in more air and let out all that it wants without backpressure?

no backpressure is bad. But you have the idea. More air is the name of the game. The reason you want more air, is so you can burn more fuel, more fuel = more power.

it is waaaaaay more complicated than that but basically yeah air+fuel=power. increase in fuel will only add power with increase in air, but your cylinder head is really what limits air intake.

!!!!restriction and backpressure dont let in or release less air, it just makes the engine work harder to get that same air.!!!!!

when you get serious into tuning, a wideband o2 sensor will be your best friend. A/F ratio is the most effective way to tune your car.

fugiot · #27 09-26-2005, 08:00 AM

Which is EXACTLY why you shouldn't even be working on getting more air into your engine anyway. Your money is best spent on other more effective areas.

actually reducing restrictions will allow more air in the engine. Your right about the engine working less to get that air, but it will also allow more air in. Since air is compressible when the intake valve opens air doesnt flow in as fast as the piston goes down. when the piston goes down it creates a vacuum and then air comes in. With less restricions more air will have flown in before the valve shuts again.
and still, like you said, it is a little more complicated than that.

fugiot · #29 09-27-2005, 04:39 AM

although no restrictions are a good thing for intake, you need to have backpressure for optimal exhaust speed. Having the perfectly sized piping will allow a balance of high-flow and airspeed, the perfect balance is what gets you the most HP.

so you mean the 10 inch exhaust piping i just bought wont give me more power than your 2.5 inch piping?
