well i think i'm the only one with an H22 here.. 1/4 mile is 1320 feet, not 1420.
With full interior, full weight, i ran 15.3. But at this time, i was running with my AEM CAI made for F23, so 2.5 inches instead of 3inches prelude. I don't like stripping my car just for drag racing but if i would, i'll prolly hit 15flat if i strip all my interior and maybe high 14's...but i like racing like i race all days. Not having a time at the strip and a time a the street. Also, i have to lauch under 3000rpm because if i launch over 3000rpm with the gas pedal to the floor, i'll spin to the cut-off in 1st and 2nd gear... i need more traction... I'm thinking about putting a Quaife Limited-slip diffential and maybe some drag slicks..
But don't forget that 6th gens accords are fat, very fat... If you cam find a 3.2 Acura CL Type-S with the 6speed manual tranny, go for it. If you want a very powerful H22..go turbo.
