At last, the better side of 12.0 in the 14b powered Talon!!!

[FonZ454]

Hey Fonz! I don't think there's any boost at all until I start to let the clutch out. I'm just dry revving at that point. So, another vote for the stutterbox I'm assuming!!!Where is your rpm set out of curiousity?

Free revving, but stabbing the throttle quickly can result in a few PSi off the line.

I tend to launch at 5250rpms at Lebonan. The crappy track prep and my street tires, I've lowered it to that RPM and launch with 0-5psi. That's just getting on the stutterbox, obviously if you add more throttle, you build more load and more boost.

When I was in Ohio, on thier sticky track, I bumped the RPM to 5500 rpm and was launching with ~18psi and still bogging. I'd say boost off the line may help you out, even though you are cutting very nice 60's already.

My car actually has a 14b on it right now, I'm almost tempted to bring it to the track to see what happens

 

[Phil1320]

First off what your doing with a 14b is un-freaken-believable (to me anyways). People go fast with big 16g's and fp greens all the time. How many other people can say they ran 11's on a 14b. Maybe a handful if that.? I say keep on pushing it.

Good Luck

Thanks alot DJ!!! That's a nice compliment! I think the fast 16g's are really impressive, and yeah, you'd expect a pretty fast machine powered by the green. There are actually a maximum of 10 cars in the 11's on the 14b. I think it is 9. There is definitely one car on the list that is a 3000GT VR4 with TWIN 14b's at 11.83 and there is an almost identical run that I think is another 3000 but don't see him on the 3000 list. So, about two handfulls. Still a small number for sure. In my opinion the 3000GT VR4 shouldn't be mixed in so I act as if they aren't there, but, it's the 14b list, not the T/E/L 14b list. Thanks again man! I'm hoping you may be able to datalog some passes for me in the future if we can coordinate that.

I stab the throttle to get rpm's up in the realm of where I want to launch and then hold a given rpm before launching. I have heard people continually stabbing the throttle even up to the point of letting the clutch out, I don't do that. So, I would say I'd be launching with 0 boost. Thanks for the props on the 60' times. I'm happy so far, but, I think the car can run low-mid 1.40's with some more work.

You should definitely go to the track on the 14b, why the hell not?

You bet. Like I said before I'm itching to see those logs myself. I should be at the track more often now that the dsm isn't my daily driver. I only do saturday's though. I'm waiting for my external wastegate to get here and I may even drop in the cams while I'm at it. Boost spikes are no fun to tune around.

Ok, that's great. I don't go to wed. nights with the talon anymore. It would only be weekends or a Friday Drag Rental Day at LVD. Would you be available for Epping, NH? I don't know where in Mass you are....

Sounds like you have some work to do....did you get the ingalls rear upper arms yet? You'll love the external gate, the cams I can't speak for!

I just noticed this thread . Congrats, Phil!

I just remembered that I was going to borrow Bruce's cars to slap on a 14b on it for a weekend. But I have been super busy on my new job, so I am not sure that I will time for it .

Thanks alot Leon! Nice to see you up here on this thread. Yeah, can you believe it? Ha. Took me long enough, but, better late than never definitely applies here. I think "12.0" will still be engrained in my mind until this fully sets in!

So, Bruce's cars? You have no DSM at all? How bout that Triumph....14b...RWD!

Thanks again Leon! Hope you get the chance to run this summer.

Phill Vs. Leon pt. 15. Let's get it on, it'll be like old times.

Probably won't be like that anymore considering neither of us hold the top spot currently. I think I'll leave the "old times" in the past and concentrate on covering new ground.

 

[GRNDSM]

Actually, I have been daily driving a 95 GSX for the last 9 months, but it is realatlively stock. I also have 93 Summit Wagon AWD, which will be fast, but it isn't there yet. And I just picked up 96 Eclipse Spyder GST, which will be a fun, but not very fast car.

So even though, I have plenty of DSMs, they aren't "record contenders". Bruce's car is MUCH better suited .

That's cool. The Summit sounds like fun. You still lost me with Bruce's car. If he has a "record contender" why isn't he driving it? Is this Hallman's old car you're speaking of? Well, anyway, Good luck with whatever it is you're doing there!

OK the chip's on the way! Just a few tips for using the stutterbox.

If you want no boost, just hold the gas pedal down about halfway, or until you hear the engine lightly bouncing off the stutter limiter. This should let you launch as if you didn't have a stutterbox. If you want a little boost, hold the gas pedal down about 3/4. If you're going for full power, floor it. If you're not getting enough boost before the launch, floor the pedal for a few seconds before launching. Boost will gradually rise the longer you sit on the stutterbox with the throttle floored. Don't sit on the stutterbox at full boost for longer than 5 seconds since it's hard on the turbine wheel.

The stutterbox code I'm putting in the chip is what I call a 'fast reaction' stutterbox. Basically the stutterbox cuts out as soon as the clutch pedal lifts a few inches off the floor. This will let the engine gain a few revs before the clutch engages. Other suttterbox codes wait for the car to move before letting the revs go over the stutter limit, and by the time the car moves you'll need much more revs. So you get the good stuff in your chip. Let me know if there's any questions.

OK! I guess I'm really late to the game with using this stutterbox. I'm sure everyone up here has been using it or knows how to but me Ha.... Sounds like it should do the job and hopefully will help the launch and runs. I'm anxious to try it out. Thanks again for opting to help my efforts to get all possible out of the 14b! Now, only time will will tell!

 

[SBstar]

Sweet! I need to find an eprom and have pneumo burn me a chip now haha. Quick update for me is my car is now up and running, just need to iron out a few things before a quick trip to the track for some base times. Hopefully Phil will have some updates to keep me motivated by then!

How are you setting yours up? What are programming the ecu to check/compare before enabling the stutterbox?
General stutterbox uses the speed sensor as a check and discontinues when car moves a few mph.
I'd like to give yours a try, too!

Just got a call, my turd is up and running.

I just rearranged the order of checks. The original code developed on the DSM-ECU list has the check for VSS first, then it checks the clutchswitch. I check the clutchswitch first, then VSS. I like the quicker reaction when it's set up this way. During a launch I'll see the revs spike up a little before the clutch engages, so the stutterbox is certain to be off when it's time for the car to move

Got you! I'll have to try it out and compare the results.

Congats thats really nice to see! Im sure it gives alot of people hope with these turbos!

Was it at a shop? If so which one in this area, now with extreme gone, i'm looking for some resources.

Thanks! The 14b can definitely go alot further than most people choose to take it, that's for sure. Most are bolting bigger turbos on as fast as they can. When you are dealing with full weight street cars you are limited as to how quick an ET you can run. Either way, still a fun car to drive.

 

[rhamlinii]

RPS in Glen Burnnie, Nate is the owner/ tech that did my car. I used to do my own work, however I cant find the time being a Store Manager and in a relationship. They can order parts, but they can do there own welding and fab work aswell. Rob the other owner isn't a bad guy either.

ok?

, not high jacking your thread. I'll make a thread about my car after I run some numbers with my 14b car. When can we plan to have you take your car back to the track.

 

[Phil1320]

Not a huge deal at all, I just never knew anything about your car being at a shop, so it was random to me.

My car? Hmmm. Not sure when I'll go back to the track to be honest. As you have read, I don't get to the track much. The rest of the month is gone unless I go this Saturday. But, I generally like to make significant enough changes before I go back each time. Although I think I might have another tenth in it right now with trying some driving stuff out, shift points, etc. The stock seat is back in the car with 2G seatbelt. That probably added a bit of weight to the car over the Sparco and harness---had to do it because of improperly mounted, harness too old, and only 4 point. NEVER had a prob in the past. They are cracking down on rules stuff lately, and good for all on that. With that said, I'm not buying a harness or sending one out to be recertified every two years, not for drag racing anyway.

On the flip side, I've countered that small weight addition with removal of the front swaybar, rear strut brace, and exhaust system, there is a 6" pipe off the turbo now. All hangers and brackets were removed as well. Now, the lightweight doors have to go on, that should drop about 80 lbs., POLK control arms should be on the car in a few weeks, said to drop 11 lbs. per side, and I still have lexan rear 1/4 windows to go in, but its a shitload of work for minimal weight savings so they will probably stay wrapped in bubble wrap this year. Also, I will be experimenting with the stutterbox as you have read. There may be a few other pneumo's own mods in there as well that will help. Collectively, we have decided to leave the balance shafts alone until the motor "needs" to come out of the car which might be never. So, that leaves a camshaft change as far as motor mods.

Other than the above, all that is left is tuning, more weight reduction, and improving on driving. That will wrap up my quest with the 14b. This year may be it. I can definitely make the car alot lighter, probably in the area of 2100 lbs. The money and time it would take just might not be worth it. I'm not spending $$$$$ on brake man unvented brakes for drag racing. They dont make a vented rotor for the 1G, only solid, so that kinda shot that in the foot. Although, I think the brake man stuff is sick, I would much rather buy larger Wilwoods from TCE for less money with roadracing in mind, however, I can't do that now as it requires use of 17" wheels. I've pretty much exhausted all the options other than what's listed above. I will consider carbon fiber doors and fenders as weight reduction options, but damn that stuff is expensive. I've got my eyes on those billet motormounts at MAP I think...a bit of weight savings, I think 3.5 lbs. over stock is what they advertise, and some bling for the engine bay, which I don't really care too much about anymore.

There you have it. As always, I open up the thread for suggestions and comments.
