Integra Type S @ WSID

[damo46]

hey guys just wanted your opinion if you know what the integra type s dose down the strip for 400 metres stock standard as ill be heading out probly this wednesday... diconected the axle back and will be removing the spare tyre and deflating the front tyres for some better launching... thats how it will be setup.... cars bone stock
hoping for a mid 14 if thats possible
also my main question is what mph should i be expecting for a stock type s and for a mid 14 sec pass

thanks

you have to run full lenght exhaust at street meets otherwise they will tell you to go home unfortunately. I'm not sure what exactly they classify as full length, however if i were you I would make sure of the rules before you show up with no axle-back. if you will be taking it off in the carpark then i guess that's okay. I remember yonas telling me he tried to run a half length exhaust and they pulled him up for it after his first run. It is a bit stupid, but them's the rules.

Better to get a thin walled lightweight straight pipe made up which will simply bolt onto axle back flange. Cheap and easy

ive ran other cars with this same operation.... the stock muffler is still visible, just disconected..... thanks anyways guys
any opinions to my thread anyone....

depending how good you launch and change gears you're looking around 14.8-15.0

Stock Type S are pretty slow, because they're heavy.

mid 14's is very possible...just deflate your front tyres to about 18psi, and inflate your rears to about 45 psi...take out everything you dont need, ie floormats, empty ur glovebox, just little things like that. i saw a stock standard type s run a 14.3 so its doable...just get out there and have fun!

Ive achived around a 14.6 using one of my mates G-force computer thingy's but that was b4 i done intake & exhaust!

the g force computer isnt accurate

sorry this might sound liek a noob question but why would u put the fronts so low and rears so high??

cause its FWD

I know but it gives a pretty dam good ball park figure, i done it from a stand still at the toll gates on the M5 @ liverpool.

lol i know that much but what does reducing the tyre pressure in the front and increasing the back actually do?

[burak213]

what i was thinking, is that low tyre pressure at the front is for more grip and better launch.

The back are higher because it has less drag so less surface on the ground which reduces 1/4 time.

[2002 TeGgY]

^^ spot on!

[johnprocter]

learn something new everyday ! cheers mate

[damo46]

yeah id like to strip it hardcore but its a mates car so just gonna be removing spare tyre and few other small bits... anyways thanks guys and ill post up some results later...

On top of the usual tyre pressure changes, you can also reduce weight by also only pouring approx. 1/4 tank of fuel on the night :thumbsup:

Lame, but every litre/kilo helps =)

good try but not actually relevant - the higher PSI is to keep the rear (non driven) tyres firm and keep the load towards the driven wheels. IE in a FWD the idea is to keep the rear stiffer than the front :)

14.3 Stock out of a Type S? What year? I had a Type S and the best I could do out of the stock engine without any mods was 14.9 with a 2.2 60ft.

Tyres do make a difference depending on track conditions. Some tracks are stickier than others. I found that settings revs at around 3,100-3,400rpms and feathering it fast guarantees you from a lot of wheel hop/spin and allows you to build up before 2nd gear shift. My best time with a CAI was

2.1 60ft
14.3@95mph

No other performance mods done. I did find that stiffer springs, poly engine mounts, and practice helps a lot.

Results.......
well for a first time out for my mate whos never been before to wsid before was pretty good with plenty of room for improvement and potential.....
front tyres were on 18psi and rears we forgot to inflate..
Car was in full trim with only spare tyre removed and floor mats ...also half tank fuel

1st run was 15.0 at 94.9 mph...with 2.4 sixty footer due to 2000rpm luanch lol.. not bad for his first time although good mph showed solid 14's were doable

2nd run was better launch at 3500rpm although missed 3rd.. 2.25 60ft..... 14.9 at 94.8mph

3rd run was taken by me.. ive been before so i wasnt nervous... luanched the car at about 3800rpm although slipped the clutch to quick and got a 2.30 sixty footer and 14.8 flat at 94.7mph

4th run was another 14.8 at 94.9mph..... with a bad 2.35 60ft

5th run was by another mate who had never been down the strip and got 15.2 missing 3rd gear and a not so good luanch

Main thing was fun night and we know what the car is capable of
Its got a 14.5 in it no problems.. just got to get new front tyres as they dont have much tread which was causing the wheelspin too much
car may also go better if the rear muffler was conected.. think it lost some torque
cheers

oh ok...i knew that it's to keep the rear tyres firm and keep the load towards the front wheels...but i also thought it was to reduce drag as not as much tyre surface area is in contact with the ground...which is why pro's use thinner wheels/tyres at the back :confused:

[2002 TeGgY]

btw, thats not a bad result for first time damo46...tell your mate to keep at it :)

[damo46]

thanks man..it definately had a mid 14 in it tho the front tyres were bald...but yeah now that hes got some experience.. he might be putting a gruppe m intake and some tein coilovers in setup with the help of phil which would be a nice simple setup for him

pros are searching for every last 10th of a second in drag racing. Everything counts.
Not relevant to yours or any other normal road cars tho :)
