The 14b Drag Race Discussion Thread

[9!'clipseDOHC]

What kind are airflow number are you guys seeing on your 14bs? I just started WOT tunning with v3 on SD and so far I've logged a best of 29.4 lbs/min. Just trying to see how that compares to other setups. My 14b and 2g manifold are both unported.

*sigh*

Lame update but I got the new bushings in the subframe and mustache brace, also managed to pull the old subframe out. I would've had the new subframe in but other duties keep pulling me away from working on the car. Suspension was supposed to arrive today but nothing so I'm hoping for tomorrow Obviously I think these will be key to getting me into some better 60 foots this year. Trying to take advantage of this good weather to get some stuff done. Hopefully this weekend I'll find time to get the subframe back up and in, the new suspension mocked in (going to have to play with height obviously), and the driveshaft and T-case back in.

EDIT: I have no idea on airflow numbers, haven't really payed attention I'll try to get a log and check it once the car is back on its feet....errr wheels

Megan Racing Coilovers arrived, hoping they live up to my meager demands. They sure do look pretty haha

 

[9!'clipseDOHC]

Wow, this thread is dead. So nobody else logs their airflow? I hit a new best of 31.8 lbs/min at 6,900 RPMs today and I'm still just getting started with my WOT tuning. However I don't know how that compares to anyone else. I know the 14b is supposedly rated at 30 lbs/min but I'd like to see real world results.

If you're revving it to 7k or better, I would hope you're not just starting on your WOT tuning. I would hope you've already done a bit...especially at the boost/airflow you are talking about.

I don't have my car running (it's actually being stripped down even more since I bought a second 1G) or I could log what I get. Some people should have some info. Like you said, the thread is just dead right now!

Everything is stable on the log, just made a third gear pull to get something to work with. I've actually only made two WOT pulls since switching to SD, both being logged and then making adjustments. Now I'll be working on dialing in the VE table (lots of thanks to Corey, aka Gofer for the help!). Boost is only 17-18 psi (at 4,900 RPMs) by the way but it tapers off to 13-14 psi by 7,000 RPMs. Not sure whats up with that, It's a 14b, not a T-25

 

[SBstar]

It's the lull before the season kicks off. Bushings and suspension are on now Should make for a better ride. I ordered a case of Brad Penn oil and after doing an oil change she should be rolling out of the storage unit. Then there's a little TLC to the interior to make it liveable and I'll be ready to start checking my tune and go make some passes in late April, early May hopefully.

 

[domthebomb11208]

for you guys chasing the 14b record...

how high you shifting these cars? i know the 14b runs outta steam up top.

and what about cams?

or is it a secret? i tried search thru this thread...haha didnt relise its 53 pages long

 

[red1993gsallmt]

i hear some these 14b guys are running a smaller cc head off a certain hundai, there are lots of little tricks. the fastest i ever went in my old 14b car was 12.4@112, but that was with bone stock internals and the stock side mount intercooler, the dogbox racing trans and shifter is what first put me in the 12s. dam i miss that car, for some reason it felt faster then my 11.2@125 hx40 car i have now. it didnt pull up top as hard but down low it was a blast, i remeber by shifting at 6800 instead of 7200 i went from a 12.8 to a 12.6. dom, ask brennen how fun my red 14b car was.

 

[1SloEvo]

I would guess shifting would come in the mid to late 6k rpm range. 6400-6800 rpm or so. I think the best setup would be a 2g or small cc hyundai head, small aftermarket cams and cam gears to adjust the powerband.

 

[Pirrofab]

For a while there was speculation that a 7 bolt head and evo 3 intake with a non turbo t.b. was a possible winning solution to match the 14b. Cam selection wouldnt be bigger then 264 imo just due to powerband and flow limits of the turbo. No need to go past 6700-7k if thats were it stops making power. I know on my old fwd 14b I would shift at 7k. Peak hp was at 6800. My set up was very weird at the time.

Ok guys I need some help here maybe I should read this whole thread but its really long all of my answers are probably on here but its too long to read every single page. So if you could send me to the link for the page or just help me out which ever is easier.

Let me start out with this. I have a 95 gst I JUST got it running on thursday. I have a ported and polished 14b. Ported and polished the cylinder head, I just made the Intake a little bigger didn't change the shape at all, The exhaust is huge. I have a 2g ported and polished exhaust mani with a 2g ported and polished o2 housing. I have a full 2.5 stainless steel exhaust. I have a side mount(for now) with hard pipe kit with greddy bov on waste gate pressure for now till its broke in. I have stock fuel system. Pretty much completely stock. I rebuilt the motor so all maintenance is done.

I know I need a mbc, boost gauge, 255, injectors, dsm link, a aem uego, afpr, and a fmic.

My goals with this car to run low 11s or high 10s, What do I need to do and what else would I have to get to do this. If this is in the wrong section, mods please let me know or move it.

Thanks,
Don dsm4life

If you're on speed density that airflow number doesn't mean much. It needs to be set up perfectly to provide accurate airflow numbers since they are now calculated, not measured. Our best bet for solid airflow measurements would be numbers from a 2g MAS since they are very repeatable and comparable from car to car. WOT tuning normally wouldn't affect airflow appreciably, but on speed density, it will, since you're actually changing the VE value used in the airflow calculation when you're dialing in the VE table.

The 14b will do 30 lbs/min pretty regularly, a pound or two higher in nice cold air. Mods on the car hardly do anything for compressor-limited max airflow. The limiting factor is the compressor wheel and compressor inlet density.

It sounds like you've done some maintenance and have or are planning to get the typical parts, but to go 10s or 11s on a 14b takes more than that. I would start with reading the whole thread for ideas. It's long indeed, but still easier than what you're going to have to do to hit your goal. You're generally looking at some combination of the right mix of parts, good tuning, exellent driving, nitrous, extreme weight reduction, and really good 60 foots, in no particular order.

Ahh I see. Thanks for the explanation.

Hi. I haven't been able to work on the talon at all. Gettin a super slow start to the season here. I probably won't do 75% of the things I envisioned. That includes pulling the head and installing the cams. The valve springs are pricey and that's alot of extra work. Most likely will remove the balance shafts and slap the engine right back in the car. That's that. I won't be doing most of the weight reduction items either. No fuel cell, no removal of rear swaybar, and most likely no front tubular crossmember. There will be some slight weight reduction from the factory wiring harness and the front tubular control arms, but, that's about it, so not the 150 lbs. or so that I thought.

So, that's it. One more time to the strip to see if I can beat my own personal best of 11.49 and then it's time to throw in the towel. That is my only goal with the 14b. If it happens, cool, if not, no skin off my back.

I'll be back if there's something for me to contribute here, otherwise, I'll let you all know how my track visit goes. First opportunity is June 10th. Somehow I don't think I'll make that, so it will be late summer or early fall. Peace.

That's too bad Phil, but best of luck to you nonetheless. I look forward to hearing how you do. Good luck

 

[SBstar]

Wow, too bad Phil. I'd ask what was up but I can come up with the scenarios. Life is tough and play cars don't always fit in. We'll be rooting for you to best your time though! You're keeping the car and going to work on making it more suited for autocross/roadcourse stuff though right?

My car is back running, I still need to do the suspension tweaking and an alignment. Then a little clean-up in the interior and I'll be ready to hit the track and start tuning again. Hoping this week to get alot of that done.

 

[e85_4g63]

Phil, sorry to hear your interest in drag racing is going away.. Hopefully you see an 11.48 or better!

Shane, do you happen to have any Auto stuff you would sell? (pedal assembly, shifter setup, or TCU and wiring? (awd or fwd doesn't matter does it?). I'd like to use a 2g auto trans (fwd).

 

[SBstar]

I don't have any auto stuff sorry. With all the auto stuff going on it does sound enticing, but then I remember how boring it feels to drive an auto. I guess perhaps I've just never driven a really fast auto.

 

[Kevin Jewer]

My race car and Mightymax are both auto, and they're plenty of fun. I do still see the appeal of a 5 speed for a street car though.

Mighty max w/swap just sounds like pure fun. And a car like yours would be fun regardless

 

[Phil1320]

Thanks guys. It's all up in the air now. Not sure what will be done as far as mods, but it will however be minimal compared to what I thought. I have not had the chance to work on the car. I walked by the engine the other day, that's about it. So, no June 10th drag passes for me. If I run it, it will be later in the year. If I don't get the chance to run it down the strip this year, then it looks like my last pass was the one the turbo gave out on. So far, I'm keeping the car, yes. And, it will be getting set up for road racing. I have an appointment later in the year for a full rollcage to go in the car. Nascar bars on driver side and all. Once that's in, any small turbo "record" pass possibilities are out of the picture for good. Will I ever drag race again, I'm sure, but the record runs stuff will be a thing of the past for me. It's just not in my blood anymore. My plan to run once more was going to be like a farewell to the dragstrip day. If it doesn't happen...me and the talon bid our farewell by sending the turbine wheel down the strip at 100 mph. And, that may be the end to the story right there. We'll see. It's finally starting to warm up. I need to clean the engine bay, make some cuts for the short route I/C pipe, and paint the engine bay and start getting the peripherals back in the car. I also need to make some decisions about the engine. It looks so damn dirty in the head and on the valves. I'd really like to freshen it up. Still need several parts to get it all back together properly. So, that's my update.

 

[SBstar]

I'd hate to see ya go Phil, but it's been a great run. Good luck on the road course either way! It'd be nice to see you get out with a few "horsepower" parts on the car and see what it could do. But I understand where you're coming from as always.

Finished getting the car road worthy yesterday. Just have to finish some interior clean up, front headlights (covers mounted), hood pins, and then pull the laptop out and check the tune. I think I'll be out early May if things go well. The new suspension feels good and solid, definately much stiffer, and the new rear bushings seem to be a good upgrade. Feels good to drive the rattletrap again haha! I also need to get an alignment of course.

Thanks man.....it will be a bit weird. It has been a great run.....and a super long run. I bet there's noone in dsmland that has run the same kind of turbo for 14 years plus, or for that matter, THE SAME turbo.

I will do my best to get one last drag strip visit in this year. I have more going on outside the car world this year than I did last year, and it was not expected. I thought this year would be a much easier year.

Therefore, with my minimal time to participate in extracurricular activities, I need to turn my attention to the roadcourse. It's an either/or type of thing. In 07 and 08 when I ran the roadcourse, I did not dragrace. And, in 09, when I did dragrace, I didn't run any track days. So, now it's time to concentrate on that and not confuse it with drag racing mixed in. Even if I used the VR4 for roadracing......I'd still want to be out on the track in the Talon. Not to mention the talon has all the bits and pieces. I'd have to dump thousands into the VR4 to prepare it for the type of driving I do on the roadcourse.....and it's still a registered streetcar. So, I'd be limited.

 

[SBstar]

Trying to keep this thread alive until we have some numbers. My car is ready to go minus the alignment. I've decided to save up a few bucks and get the adjustable rear control arms so I can dial in a proper alignment. I'm looking at the 3000gt units as people seem to be having great luck with them, and they're cheaper and have a better track record then the ingalls units. As far as the alignment a little research suggests stock alignment for the front and putting the rear around 0 camber. Does this sound correct to everyone or are there different suggestions? I'm planning on taking my old shell to the scrap yard this weekend so I'm hoping to have the cash for the rears.
