when i owned my 99 Si(R), everyone on the clubsi.com site who did run a low 15sec. 1/4mile did so w/ a mph of around the high 80's. i.e. 89mph...etc.

however, many and i do mean many, Si(R) drivers were getting horrid times constantly. like in the 16's and 17's. of course they complained about how their engines sucked and so on but, it really came down to the fact that the drivers either didnt drag well and/or their engines really did produce less hp than advertised. but this is common of all makes and models.

as far as the discussion regarding backpressure, a little is needed for NA engines or you end up losing low end torque and hp...I think this would be important in good 1/4 times as you need to launch and pull hard to get a good time.....as far as double clutching and heel and toe...these 2 techniques are closely related and both are for accelerating out of a corner so hardly a drag technique

you guys were talkin about heating street tires...
i noticed a stupid cool time loss between the 2 first races last friday.
i had 215-50-15 in front,i dont care about pressure.
first run i didnt burnout long ,just 2-3 seconds.i got
10.810 thats crappy,i spun like hell at the startline..
second race i burned the tires alot longer .I had a better reaction time,and i got 10.336.
i noticed that the more i heated the tires,the less spinning i got.
thats a bone head proof that heating is good.
but i must say that my tires are getting old.and slicker.must have helped..

There is no way, that making your radials hotter, gives you quicker times. It only gets the rocks & garbage out of tires.

ive been at the track a few times,and i assure you,it made a difference.
logically,if you dont heat them and spin at the start,youll lose time.i heated them,and i almost dint spin,got a better time,and i always dump the clutch while revving at around 3000rpm.
so,yes it does make a difference.try it for yourself.youll see.

Bro, I have been drag racing RX7's for almost 10 years now.


You're just burning up your tires and wasting your clutch and money. Only slicks benefit from warming up. Radials get no such benefit, the rubber is a different compound.

i understand
but as i said
my tires are almost slick worn
it may change something
i know my tires we not really getting ''softer'' or stickier,but i guess it helped adherence on the sticky stuff they spray on the ground......what do you think?

Sticky stuff they spray on the ground??? I don't think they spray anything. The only benefit from doing a burnout with radials is getting them clean.


I think you just drove better the second time.

i think at least 2-3 guys here live near montreal thats cool we should meet some day at the st-eustache 1/8 track.would be cool

There was an article in SCC two months ago (RSX test issue) where they tested a Mickey Thompson Drag Slick, BF Goodrich Drag radial and some Falken street tires and they said that doing a burn-out on the Falken's made them slower. You can read the article on www.sportcompactcarweb.com I believe.
