ok, i have a 95 GSR coupe. currently, my only power mods are an AEM CAI and the APEXi World Sport catback. my question: if i got a header and a VAFC, set the air/fuel ratio just right, and dyno tuned it, do you think i could run high 14s? i got this idea from a fellow honda-tech member. he believed i could hit a 14.8 or so. also, i think i would want to go with a 4-2-1 design for the header. i don't want to sacrifice mid range torque. maybe a DC or APEXi header. what sort of hp figures do you think could be achieved with this setup?

let me know. thanks.

 

Yes you could run a 14.9999999 as long as you are a good driver.

 

HIGH 14's - yes.
Power - 150-160

 

i should also say that i will not be gutting my interior. the full interior stays.

B2FINITY, read this post, and then see if you change your mind. https://honda-tech.com/zerothread?id=617893 i just ran across this a few minutes ago. this backs up my idea that i could hit high 14s, and makes me wonder if i could do better than 14.8 or 14.7. i'll also note that i am a pretty good driver. not awesome, but pretty good. prob not as good as the guy who made the thread that i have the link for.
anyways, thanks for the replies.

 

hmm...b2finity, i see you have already seen the post i tried to show you. any thoughts?

 

if i/h/e stands for Intake/Helium/exhaust, then i would expect running near 11s, low 12s.

as long as you have the stand alone helium management unit.

wtf are you talking about...and yes 14s are definately achievable, just learn how to launch/shift properly

 

hahaha. helium?? Headers. the H is for headers.

i'm pretty good at launching. very minimal wheelspin and i'm outta the hole quick. shifting isn't a problem either. being that i already have intake and exhaust, would you recommend another mod or two mods for about the same price as a VAFC and a header and dyno tuning. the closest dyno place to me charges $130 for 3 runs. so i was thinking the vafc, header, and dyno runs would cost me about $600 or so. ($220 for vafc, $250 for the header (i get wholesale parts), and $130 for the dyno.) so if anyone can think of another mod or combo of mods for that price, other than N20, please speak freely. i don't want nitrous.

 

try to find used a header and a used AFC, and find some cams and cam gears.Then use that $130 to dyno, its not worth the dyno for i/h/e.

 

You could definitely hit 14's with I/H/E and a full interior. If I was in your place and I didn't, I'd actually be kinda pissed/disappointed.

 

Get a highflow cat/testpipe

Never understood why people spent the money to upgrade the header and exhaust, but leave the peeshooter sized and ungodly flowable stock cat.

 

Replace the WorldSport, it's still a big bottleneck for your top end. For instance, I noticed an immediate improvement going to the RM-01A.

CAI is okay..with the AEM you have a big power hump in the midrange.

Interior - weight here is your big issue. Aside from improving the breathing of the motor, your weight is what will kill your times. Take out the spare tire for running (leave it in for DD)...take out the back seats (takes 5 minutes)...take out all the spare weight and get some lighter wheels.

high 14's with weight reduction and bolt-ons is easy.

 

I got some of the same suggestions as the others. But here it goes.

First off I would trade your Apexi WS and get an exhaust that flows freely all the way through (bottleneck that tweaikster talked about).

Then, I would purchase a good header. This is all depending on the money you want to spend. For the money you mentioned....DC sports makes a good header for the money. You definately want to grab a carsound cat or some sort of high flow cat to help the air flow in your exhaust.

You "CAN" tune your car with the VAFC w/ just I/H/E/C. But your not going to see great gains, you will see minimal gains though. If you really want power then spend 300-350 and get some ITR cams. then, of course you could get cam gears, lighter rims, better tires, suspension setup and so on. Goodluck with your setup.

I think you'll hit high 14's if you can drive.

 

you could hit 14.9 right now, especially on the east coast.
I ran 14.9 with an exhaust and up'd vtec at MIR.
Strip your rear seats and spare tire and your in 14's

 

possible yes

most likely no

 

I ran a 14.8 with just I/E full interior, spare was there and everything. It was also with a "shitty" 2.3 60'. Granted, my car seems to be a freak based on the linked post above. I think he can hit high 14's easy. I see it all the time. One thing that matters is elevation of the track. They have corrections for that anyway. Another important thing is launch technique. A lot of people think its all in the 60' time. It really isn't. I can get a 2.1 60' but not run very fast in the 1/4 compared to gettinga high 2.2 60'. If you drop at low rpms you have a good 60' but you aren't in the power band after the 60' mark and you run slower. Thats why, as seen in my vid, I launch higher, and after the wheels grab, I'm only in first for like 1500rpms. As far as the mods. If you do a lot of weight reduction and launch/drive REALLY well, I could see a 14.5. My friend tuned his I/H/E Lude with a VAFC and picked up 8-10 midrange and 4-5 peak hp. Get a good VAFC tuner. So, in short, yes, 14's are very possible.

yea, a good driver and a gsr with those mods can break 14's.

 

Yes if you are a good driver.

&lt;------still saving for light 15" rims and tires so I can get to the 14's
