Ok from reading N/A forums, they seem to get into the 12's or lower with 210+whp considering its tuned well with a good set-up and driver.......so im wondering why would i need anything more than 300whp with a turbo, that spools reseaonably, and good lsd?? because anything higher than that will equal lots of wheelspin right??

Im asking because due to money i might have to keep my lil engine that could(sOHC), and build that, which i think i can get around the 300-325whp mark......i just want to get into the 12's with full interior and street tires(plus size rims) thats all.........sorry this question has been urking me, and i couldnt find a straight up answer searching....

traction.

and i am fairly sure you shoudl be able to et into the 12's w/ 300-350hp

weight reduction

N/A drag cars have different powerbands so they can make a nice amount of torque down low and lots of power up top. nice and progressive. also lots of weight reduction as was already mentioned. the suspension setups are tuned really well and slicks are used of course.

the turbo cars are normally heavier and don't always make power soon enough depending what setup is being used. if you run a N/A car with 225 WHP and another car with the same weight/tires/WHP only with a turbo setup, the N/A normally would stay out in front though that's not always the case.

alot of the pros run close to 300 WHP on their N/A setups and get into the 10's with the right slicks/suspension/tuning and a driver who knows the car well to launch it off the line. N/A street cars can hit the 12's with enough work, tuning and slicks, even without tons of weight reduction. a light chassis (1900-2200 lbs.) with 220-240 WHP should normally get well into the 12's, whether N/A or turbo.

i've seen clips of 300-350 WHP turbocharged Civics making it into the low 11's and even high 10's. seems too good to be true but it's possible.

I have 220whp / 153wtq.
13.5@107 w/2.3 60ft Should be good for a 12's with traction.
Note only the 60ft.
But traction through the gear changes also.

Its got to with the way that the cars make power. NA cars power curve is much better then FI curves. Our car weighed 1700 when it ran the 11.53 but was not making anywhere near 230 whp...more like 220 or so. Its the curves on the 2 motors that make or break a car. our 60 was 1.55 which is pretty good for the e.t.

Okay, i am starting to get the concept, so now i ask how can i go about getting a setup that will yield me around 300whp , spool up pretty quick around 400rpm im thinking, and still pull on the top end?? am i dreaming or can this be set up on a SOHC, yea i know i probably really killed it with the SOHC but with a number like 300 it seems possible to do it with lsd, and the right tranny, and some driving skillz........with street tires and i only plan to take out the carpeting........but thanks for breaking all this down too me, maybe this can be a goal i can set to prove a point or something

i don't know about making 300 WHP with a D16, but you may get 300 at the crank with the right setup. i don't see many built D series motors and i don't really work with them so i can't help.

my theory is if you want to buildup a D series all out, then might as well take that $$ and do a swap with a B16A, B18B or B18C. i know to some this makes me a D series hater and i'm not trying to spoil your plan for a fast D16, but the B series are more durable and you can run them bone stock or close to it and make good power. then when more $$ rolls in the internals can be swapped out on the B series motor to run more boost and make more power.

that's the way i see it. either way i hope your buildup goes well.
