Motor is a B18c5 inc jun 3's & jun valve gear, RPM 68mm TB, CTR intake (motor came without one), DC Sports B16a 4-1 header (need ideas whats better here), Y1 tranny inc LSD.

Run was on 195/50/15 toyo proxis set to 22psi it was a bit cold but I'm over in the UK so it just is!

60ft 2.258
330ft 6.030
1/8 ET 9.213
1/8 MPH 77.65
1/4 ET 14.191
1/4 MPH 98.19

Any tips or ideas what I can do to improve I hope to have sum better tyres for my next runs (tarmac rally tyres as we have to run on street legal tyres to race over here)

Rev it to 9grand a mugen chip and maybe a new driver.

 

what kind of car.. ditch the header ofr a 2.5 collector that should be enough right there for 100mph.. Considering you have those big *** cams and a low flow b16 header.

What computer/rev limit you got?

 

Yeah the header needs to go but I'm over in the UK & we dont get much choice on bits as most of the really good stuff isnt shipped

BTW after the 2.5" collecter I guess I'd need a 2.5" center pipe & rear can pipe work too??

Its a custom chip set up for my motor (came with the motor from japan) but with a tad more fuel added to the map as we dont get the crazy jap fuel over here either.

Rev limit is to 9k at the mo & I'm thinkin it can be more but I'm not sure the stock siR fuel pump is up to it?

Driver wise yeah I'd got up @ 4.30am to get to the track to sign on b4 it got busy (4hr drive) + it wasnt a quick day the 9.9 skyline that was there was doing 10.3's n he's a **** hot driver!

slicks... street tires are a waste IMO

Can't drive on the street w/slicks

 

There's something wrong there. Has the car been tuned properly?

I had a gsr motor with JunIII's and CTR's, not even a b18c5..And it went 12.7@107 in an EG on radials..

You should be running atleast 103-104mph even on street tires.

 

Its not been tuned for power its just been set up to not run lean to keep it safe till it gets tuned (over here honda tuning is much more difficult as theres know shops that do it properly) I'm having to drive 4-5hrs south to get the car tuned by sum1 that knows what there doing!

& in the racing we do the cars have to be street legal so no slicks or drag radials (not street legal over here) best we can get are tarmac rally tyres (FIA spec so there street legal) which I should have for the next time I run.

TTT anyone got some usefull tips or ideas?

LOL "centre section", you brits are funny. ITS CENTER!!!!!! P.S. I assume you could atleast get a JDM header, they ship 'em here im sure they would shipem to Britain. A bunch of british guys are staying at the hotel i work at. Not once have i heard them say "thank you" or "good-bye" its always "CHEERS", every single time.

 

Personaly i would dump the 17's and the body kit if i were serious about drag racing. Whats a "Carbon Bonnet"? cheers

I JDM "header" is the same as a DC Sports "header" isnt it as the DC is just a copy of it? I was more thinkin of something down the same lines as a SMSP "header" theres a race shop about an hour away & he's the best.

& what language do you speak again english I know some words in my english are weird but hey we made them up first!

See my first post!

Drag racing is no where near as big over here & you dont like a real JDM CRX EF8 with a real Mugen body kit.... ITS JDM DUDE

Also from the first post I was running 195/50/15 Toyo Proxi's & I'm lookin for some better tyres at the moment.

A carbon bonnet you would know as a carbon hood

True but your tracks must be in much better condition than ours & our cars are heavy as stock my JDM EF8 siR CRX weighs 2134lbs (stock not sure on my car need to check that) so with me even if i strip the rear out (which i do) my cars gona be pushing 2300lbs your HF CRX is like 1900lbs

U call hoods Bonnets? hehe. "POP your Bonnet mate, would ya? I wanna have a peak under your bonnet" Anyway, i didnt mean the DC JDM, i meant any header thats made in japan. TODA, SPOON, MUGEN, JUN..and so forth. Ive been to London once, didnt understand what anybody was saying, its like a different language.

 

my car wasnt an HF. and being lighter is hardly an excuse, as a heavier car will hook up better. hence, my lighter car with more traction issues, could run good, so yours can too. no reason your car with jun cams should be anywhere near the 14's.

HHmmm I dont see may race teams adding weight to there cars to get there times down but you have a point ish + whats your car set-up not to make excuses but alot of you guys run traction bars rear cuts etc etc & what street tyres were they (do you have a vid/time slip I'd luve to see how its done)

Anyways that wasnt my point my point was what do I need to do to get a better 1/4 time? My motor isnt puttin ou the power it can at the moment due to the tune its in & the parts I'm using I guess (DC )


My time slip (tho I have had higher terminal speeds but not over 100mph yet) I know the reaction is really bad but I was racing my mate in his si n I didnt want to beat him too bad or red light

& yeah we can get JDM tunning parts but there silly prices unless I get one second hand & shipped from Japan which takes months Does anyone know of a spec list for saw a smsp header or summat similar I can get a custom header made but to what spec is the problem, I guess the main thing with the DC is its a 2" collector & the primarys are kinda small too?

BillB

 

the idea of a heavier car hooking better is counter-productive and silly. A heavier car will hook better because it is simply slower

as for the header if your gonna get one and dont wanna pay smsp price look into header-tech. they make a great header that makes great power. It makes the car like alot of fuel top end though. so make sure you do some sort of tuning with it. it also sits very close to the oil pan for clearance. I know this is an issue with EF's more then 92+

You should be able to hit a 2.1 or maybe even a 2.0 on street tires (real street tires, not Drag radials) it all depends on track condition though. did you run open header or through an exaust?

 

your running you car lean untill you get it tuned? youre only running 14.0?

99dx coupe
179.4whp
128.tq
jdm b18c with a ctr intake cam tuned with vafc
13.9 @98mph
removed some more weight, added 97spec r tranny, new mounts, about to tune cam gears, and got some drag radials on 14s hopping for 13.7s or faster

 

Your time is kind of slow for a B18C. Well mine runs almost the same time 14.3 with a 2.3+ 60 ft and 99mph trap speeed considering its just a B16A with stock cams. Do you have adjustable cam gears? It helps a lot in tuning the car.

 

I've done a fair few 2.1 60fts with street tyres with the stock b16a that came with the car but saw far I've only done 3 launches with the b18 so I'm still gettin used to it + the track wasnt that great (even the guy on the PA system said so).

What kinda weight are these low 14 1/4 cars, are they on normal street tyres & do they use Z10 traction bars etc etc? I'm lookin into the Z10 traction bar stuff & my car should be gettin weighed next week with me in

Cam gears are on my list of things to get asap prob along with the bigger header just need to find some 4 bolt+ ones (dont like the idea of cam gear slip) at a good price? The car was only tunned to not run lean nothing else no power tunning at all see above I have to drive 5hrs south to the nearest place that knows what there doing with a modded honda

nice
