first run was with a filter, second was with a pep boys open velocity stack. it ran better with the filter

1st gen b16a
-2nd gen b16a cams (still on the single valve springs though )
-blox IM
-JDM H23A throttle body
-ebay ITR knockoff header (2.5" collector)
-2.5" crush-bent exhaust to a 2.25" resonator (24" i think), 2.25" crush bent after that back to 2" right before the stock GSR muffler
-short ram intake (down in engine bay, not sticking up like a dyno queen )

-s80 tranny casing w/b16 gears
-quaife lsd

street tune done by azn kenny in about 20 minutes or so.

this is how it was running when i went to the track (before the street tune).

track vid
that was a 14.675 @ 95.43, with a 2.430 60'
after that i cut a 2.300 60', kinda bogging, and ran 14.653 @ 95.12
i need struts REALLY bad. i'm surprised i didnt break anything with all that wheelhop.

car is a 94 ex, 3/4 gutted at the track, headlight out, velocity stack on (i'm sure it helped then, since i was running so rich). track is 233ft above sea level. temp was in the mid-low 70s iirc, not sure of the humidity (if i had to guess, i'd say around 50%).

your input is appreciated
if you know of any quicker internally stock b16 coupes, post em up! i expected a 14.9 @ around 94 out of it (i previously ran 15.0 @ 93 with the only difference being 50lbs heavier and on a DC ***** header), so i was pretty happy lol, especially since i beat a guy with a straight SiRII motor w/bolt-ons in a hatch too (he was stuck in the 15s that night)

ToeJam

with the mods you have Ill say thats a pretty strong b16

what was it tuned on?

candy eg

damn hella wheel hop. haha. i use to wheel hop like that before my engine mount inserts. good times for what it is

iTrader: (1)

nice times

VTEC2841

do you have any idea the exact weight of your car?

this is similar to the exact same setup I plan on doing to my CRX

except better flowing exhaust and a whale ***** intake.. so a little bit better of a setup.. great numbers.. must be a real strong B16

Well, your car is gutted and a 94. In a 99 Si with just I/H I ran 15.1 @ 91ph is that counts. I'm not really a fan of gutting the ride, even at the strip.

pootie.teng

now why did the second run yeild less power...theoritically it should of gotten you more with the velocity stack and all rite...i really don't know...just ask'n a question...

Hercules

nice times..what kinda tires you running?

I gotta sir b16 swapped del sol, full weight on 195-55-15 ventus tires
on sunday i went 14.71 @ 94.5 with no back bumper 2.2 60'
hit 14.9's at 92.3's with the bumper on
Also hit 14.44 @ 94 with bumper on but open header

mods..
short ram intake with autozone velocity stack, headlights in
ebay header with 2 inch collector
Stock cat
skunk 2 cat back
stock everything else
2.2 60's usually every run

Your 95 traps show you have more power than me
I never really see anyone else running 14's with stock b16's for you!

Redcoupe

Damn good times.

I ran a 14.822 @ 94.3mph w/ a 2.4-60foot in my hatchback.

It weighed w/ me in it and a half tank of gas 2380lbs.

My motor was a stock Sir2 B16a with a Apexi World Sport catback. Open diff.

Only mod to the car was 99-00 Si wheels w/ Yokohama AVS ES 100s.

Had two broken motor mounts(lower ac mount and the main timing belt mount) Wheel hop was crucial. Haha.

Good times though.

88rexA6

tuned on crome (not pro)

my mounts are solid polyurethane, so i blame the massive amounts of wheelhop on struts (monroe sensatracs FTL!)

i'm not sure how much it weighed. i might go get it weighed within a few days, but it will be with full interior and all my tools in it, and however much gas i have in it at the time. when i ran at the track, it was at about 3/8 of a tank.

when my car was full interior, i was running 15.0 @ 93. i know the 14.x was in there, but there was a combination of shitty struts and a shitty driver holding it back

pootie.teng - when it was street tuned, it was done with the filter on, with the hood closed, behind the headlight. at the dyno, the hood was open (go run your car at the track with the hood off and see what happens ), making it run just a little leaner than what it was tuned for. then, with the velocity stack on w/no filter, it was noticable leaner. i'm sure if i had time to tune for the stack that day, it wouldve made more power with it. but, the filter flows plenty for the application.

Hercules - thanks, but i give all the credit to the motor (2.4 and 2.3 60's ). i was on 205/60/14 falken ziexes at 30psi (nice tires for drag...monster truck though ). those are great times in a sol too! that header is holding you back more than you think, too. the switch from the DC ***** (2" collector) to the ITR knockoff (2.5") was ridiculous for one simple part change.

Redcoupe - fix those mounts and 2.2s will be cake. hatches are so easy to launch (compared to coupes anyway). you should be a mid 14 easy trapping that mph in a hatch, once everything's fixed.


hopefully within a month or two, i'll be able to locate an ITR exhaust cam (already have the intake cam and valve springs), and contact mtber for a dyno tune. 175 SAE here i come! (aim higher than you think is possible lol)

beyond-redline

Looking forward to the results of the new dyno with ITR cams!

I have a 95 full weight del sol with a b16, mostly stock with an AEM cold air and ITR intake manifold, stock header and 2.38 exhaust. I have a dyno sheet for the engine at 160whp (dynojet). If i could get the time Hercules got i'd be ecstatic. I plan to re-dyno later with ITR cams/valvetrain on my local shops dyno very soon. Chrome tune in this car

I also have a 92 hatch, pretty lightweight( cx with some removal of weight). This one has a d16z6 with a JRSC at 6psi and it made 160whp (superflow dyno) and 130 ft lb of torque. (hondata s300 FTW!) I'm thinking about running this one this weekend at the local drags, mid 14's would make me pretty happy with that setup.

The difference with the extra torque the supercharged car makes is huge, a completely different driving experience.

Good luck and don't forget to post the results!!!

This is the whole reason why I think more people should be getting into B18C1's instead of B16's. Your supercharged D lays out close to bolt on numbers of a GSR setup. You have first hand experience how much more enjoyable the driving experience is with the added torque. I liked my B16 and all, but it just wasn't anything to write home about until 7k or so.

I had a supercharged Z6 in a coupe. All the bolt ons, no tuning, it did 14.8.

88rexA6

while GSR vs. B16 is an entirely different arguement that i've extended to many pages on other forums, i still say that for the price (swap for swap, tranny included, because b16 tranny &gt; gsr tranny), you pay about $1000 less for the b16, and run marginally slower times...not worth the price difference IMO. Azn Kenny made 2whp and 18wtq more than me on his GSR, which has a longer tranny. granted, my tranny isn't going to make up 18lb/ft, but it will put a little more torque at the wheels in each gear

that said, if i come across a GSR block or complete bottom end for cheap, i'm jumping on it in a heartbeat. i'm well aware that torque wins races

the b16 is awesome for autocross though, simply because it is torqueless

13.85@95mph 1.9 60ft on nitto 555r drag radials.

stock internal b16a
GSR cams
65mm tb
hytech productions header
JDMsh!t intake manifold
high flow cat
2.5" exhaust

car weighs somewhere between 1700-1800lbs
on the dyno a few days before that it made 161whp 118ft/lbs

candy eg

your wheel hop could be your tires too. what tires do you have? i have three friends that have real bad wheel hop with bfgoodrich gforce tires.

88rexA6

neofreak - NICE, but GSR cams isn't exactly "internally stock." i guess 2nd gen b16 cams in a 1st gen isnt either, but it's still less than a 2nd gen b16 (lower compression). however, that car trapped the same mph as me, so it goes to show you how much the 60' plays a role. that night, i was cutting 2.6s and 2.7s to begin with (dunno why. i've NEVER done that shitty). then, when i cut 3 tenths off the 60', it magically cut 6 tenths off the ET. a 13 may be in this car after all on the right tires, 2step, struts, driver, etc. that just makes me want a 13 all motor w/the b16 that much more.

candy - i'm on 205/60/14 falken ziexes, about 60% treadlife (plenty left), at 30psi. i've always had good experience launching with these tires. tall, soft sidewall and decent compound (not bad for the high treadwear rating anyway).

Hercules

i'm gonna go to the track here in a week or two again...only changes will be, velocity stack stickin out of the headlight, 185-60-14's up front, maybe a few other small things. Gonna try and get her into the 13's with no cams, i'll let you guys know how it goes.

88rexa6-what rpm do you launch at?
I've been launching the 195-50-15's with 20psi at about 6-6500 rpm

88rexA6

my 2step is set at 6500, and my ecu's vtec speed check is disabled, so i'm in vtec on the launch. my tires were at 30psi.

well i hit a really ******* huge bump tonight, and the car feels slower than when i first got it (with 1st gen cams, DC ***** header, and even shittier exhaust than whats on there now). running .5 AFR richer now, and i have a massive exhaust leak somewhere on the header. someone stole my flashlight, so it has to wait till the morning till i can fully assess the damage.

1 step forward, 2 steps back. bye bye 160whp

words can not express my rage at the moment.

neofreak

you may have collapsed the piping on the header, i've seen it happen to 2 dc headers

**** happens bro but it dose mean that u break ur self down, Fix the leaks car will run batter..

88rexA6

true. i'm not so worried about the leak, as it will be easy to fix. the dents though...
i'm just pissed b/c i've had the header for 3 weeks.
i'm running .5 AFR richer on average now, so something has changed noticably. i've never heard of anyone denting downpipes...
i think that may be my next route.

neofreak

me and a friend ended up having to drive through a construction area (no way around it) in his B16 CRX with a DC header w/2.5" collector. there was a rise in the road that he hit hard, really hard. the sound of the car changed and as soon as we could pull over we looked and the front two pipes were almost totally collapsed. i hope the same hasnt happened to you

QuickDxEk

Damn-We have some good b16 times here!! My times in my Sig.

My coupe weighed in at 2380 with a little less than a half tank w/o me!! I weigh 165.

88rexA6

old thread bumpage for new info.

weighed the car the other day. only difference in weight from that track day and when it was recently weighed is that i now have a/c (whereas all components except the evaporator were out of the car), and the car had very close to a full tank of gas (i was at 1/4 or less iirc at the track).

weight w/me in it: 2480
weight w/o me in it: 2320

with less gas, an a/c-equipped ex coupe with power windows and sunroof can be weighing in the 22xx range. i love it

dyno tune....cough cough
