14B dyno record

[firebirdvert305]

Damn all this 14b talk is making me wanna go dyno now even tho i hate my setup. Its currently has, FMIC, act2600, 272/272cams, full 3"turbo back exhaust, AFC, eprom chip tuned, 650cc inj,walbro 190, hallman mbc spiking 22psi falling off to 16psi...

i just dynoed and tuned my car this afternoon.
293 hp/ 289 ft-lbs. @18 psi. no juice
the graph show the turbo starting to fall around 5500, with the torque falling around 5900. the car/turbo have 115,000. the motor is a jdm vr4 swap, compression, 155 x4.
i am happy with the results despite knowing my turbo is on its way out.

If by stock you mean no outside electronics toying with the ECU, then all that you can do is retard the base timing using the CAS.

Otherwise, I think Apex has an older ignition timing controller (ITC.) I'm sure some other companies make something similar.

Yeah that's what i was going to do. I was also thinking of getting an msd ignition as well. I'd rather not have to mess with the global settings.

I've logged as high as 34lb/min airflow with dsmlink, but that was with a boost leak! So it doesn't count. The highest LB/Min I've logged with corrected airflow sliders is about 30.1lb/min on a stock 7bolt.

What boost were you at before you sprayed and what did it rise too? Also how much timing did you pull out. What did you use to pull timing out? I'm trying to figure out how to safely spray a 4g63, while still on the stock ecu. I used to want to try the 14b, now I have decided to do it with another setup.

Sorry, I haven't logged in for a while so I haven't seen this reply. I had an OOOOLD school EVC to control boost, so I set it to stock levels when I sprayed; it spiked to about 19-20 psi with the nitrous. The stock wastegate is only going to do so much, so even if you had the boost set higher initially, I couldn't see it spiking to much further than that anyway. Set it to stock levels and work from there basically. As far as timing, I simply used the factory CAS adjustment as previously stated. I want to say I retarded the timing down to maybe 3-4 degrees BTDC at idle, plugs were BPR7ES-11's gapped to .028. It's been so long since I've had that car that I barely remember. The stock ECU will add timing so long as you have proper fuel/no detonation. On nitrous, running like 19-20 pounds of boost, I would see upwards of 30 degrees of total timing by 6500rpm. Keep in mind I had a pretty overkill fuel system for a small unclipped 16g; 255lph HP pump, -8 lines, 660cc injectors, base fuel pressure was set at like 60psi, I had an AFC adding something like 30% fuel in the upper rpm tables, and when I sprayed, I always ran NOS 120 octane leaded race gas. With the dry kit on boost, fuel pressure was likely going well over 100psi which is not what you want, not what I would recommend, but for my car it worked and I had no problems. For a DSM, I would say stick with a wet kit. (For reference, I had an 80 shot on my car.)

I never sprayed much on the stock 14b, but with 3" exhaust, fuel pump, K&N, free mods, boost, and a 40 shot, the car trapped 113mph (fwd).

With the small 16g and all the other supporting mods, it trapped 129mph, dyno'ed 423hp/428tq to the wheels. Hope this helps a bit.

Holy crap it's Aslan.

What's up?

It's no problum. Would it be ok if I was to PM you details of my setup, and ask for some advice? If you think it's worth trying? I could post in this thread but it's I'd rather not and it has nothing to do with a 14b anymore. It has more to do with turbo/ nitrous and getting a good tune. Thanks in advance, for all the help.

oh, I KNOW I need to drive it harder, but it has 245,000km on it, and it can't shift much faster.

So you figure 105 is enough MPH? I kinda did too. once the clutch and tranny are up to it I should be able to pull out a 12.

I went 12.7 @ 105 on a stock 14, stock smic and lots of other stock parts but race gas - so I think it should be plenty.

After a FMIC and injector upgrade got down to 12.3 @ 110 on race (NLTS) and did a 13.0 @ 106 on pump (granny shifting).

No problem at all. I'll take a look at what you've got.

I just uploaded the video to youtube so more people will be able to view it.
