its increased w/ the thin headgasket & flat face valves. other then that my next step would be p30 pistons, but i'd rather just get a b18 block as opposed to replacing the pistons.

I have 191 whp in my Si, and I barely broke out of the 15's. However, it was mostly because of my launch, because from a roll, I can hang with 13.9 second cars all day long.

Your best bet will to be with a 1.8 and some good headwork. From what I've learned from past experience is that a nice N/A setup makes the car a lot faster around the street, and a lot more fun to drive, but you won't see those improvements so much on the track, mostly because theyre FWD and heavy as hell. For mid to low 14's you're going to need about 200 whp, an LSD, and sticky tires.

those 17" rims don't help either what were your 60ft times?

First time EVER at the track... My first few runs i was around 2.5-2.6, had an embarrassing 2.8 where i had so much wheel hop that it popped out of first gear twice. My 17 + 40 series tires are the same diameter as stock Si's, and they're actually lighter, its just that I have no sidewall. My car is quick, I just couldnt launch it worth a shit.

BTW, this is Purduinasi (too lazy to log out of brandons account )

Launching is a big problem with these FWD cars esp. on street tires, but its something you have to practise. I pull 2.2 on my street Hankook Ventus, launching about 4200rpm.

If you get that 2.5 to at least 2.2, you'll shave close to 0.5s off your 1/4 or there about.

4200 is very reasonable with a b20 setup, but on a b16 r b18 the higher the better. sacrafice wheelspin for being able to get right into vtec. I'm a shitty launcher, but my 2.2 to 2.3 launches usually also result in slower times and lower traps.

You just have to find the right balance for each individual setup.

what kind of tires? were you using? do you have aftermarket engine mounts?

every car is different, its all about feel on the launch. My Si i launch at about 6-7k & basically dump the clutch. then its just keeping the gas steady until the tire hook up, then full throttle. It manages me about a 2.2 60' average. Some people launch so low, i dont understand how it works for them, but i guess its feel. To me it feels like a quick launch if i launch at a lower rpm & let the clutch out a little slower, but the 60' is definatly worse that way.

I've tried about every different technique at about every different rpm, & thats what works for me. I am on drag radials though.

Yeah, I hear ya... I would have launched higher, but with the amount of wheelhop i was getting, it was starting to get scary, and I didnt want to break anything... If I could launch it like I can on the street (4-5k, spin till about VTEC and then get traction) I'd be great, but tracks tend to be prepped differently and for slicks, and that doesnt work too well with street tires. I can get full traction in second and third on the street, yet on the track, I was just spinning... I kinda wish I could get slicks on there, but then again, I made the car to be a good Auto-x/road racing daily driver, not a drag car, in which case I would have gone forced induction, or better yet RWD... enough of my rambling for now tho

with my lsvtec i found it (for me) that I got better 60ft times launching around 3200 rather than 3800 or higher. I also got my best times that way, high 14s with a stock head.

---

Wow, speaking of stock head, I am sorta confused with my setup now. I ran 14.4 with stock head B16 with stock cams/valvetrain etc. Now its mildly ported with BC4 cams and REV springs/retainers and still running 14.4.

Only thing is, with the stock head, I had drag radials and that 14.4 was once when it was really cold. Now I'll get 14.4 consistently in the hot weather and on street tires. Though I think my problem is the DC 4-1 header.
