  1. [RESOLVED] Exhaust in valve cover

    I left it parked at my dads house for the last year. However I did put about 200 miles on it like that to get it to his house, and it has been started and moved a few times. The broken bits weren't loose in the cylinder so no damage was done. After pulling the piston out the broken pieces didn't...
  2. [RESOLVED] Exhaust in valve cover

    After saving up the money for the stroker motor I wanted, and just not being able to pull the trigger to spend that much money on this car. I finely got around to taking the engine apart today. It was a broken ring land and ring. So time to get some new pistons, probably wiseco's. The bores...
  3. [RESOLVED] Exhaust in valve cover

    On memorial day while on the way to an autocross, after stopping to take a leak while getting back on the freeway I got on the throttle pretty hard. I noticed my knock gauge pegged, and blue and black smoke behind me. I immediately got off the throttle, looked at my oil pressure, still looked...
  4. awd drag launch problems

    I'm having some issues launching my car this year. Last year I was able to get 1.65 60' with a good launch, average was 1.7, with a worst of 1.8xx. This year the best I've done is 1.75, with most comming in at 1.8-1.9 with even a couple of 2.0xx.This year I'm using a 2 step at 5500 rpm at...
  5. TRE spool install

    Yes.
  6. TRE spool install

    I went for a test drive last night. I couldn't feel it in normal driving conditions. But parking lot style maneuvers suck, especially in reverse. I could really feel it binding up. I still had my r-compound tires on so maybe with normal street tires it wont bind as bad, just slip the rears more.
  7. Brent Rau Shatters ET record @ NHRA 7.09@199

    Different series, that was NOPI, this was NHRA.
  8. TRE spool install

    I finally got my tre spool the other day and I am installing it today. It didn't come with any instructions but I think I figured it out. Hoping to get some confirmation before I put everything back together.Heres some pics of how I installed it. Does this look right?
  9. boeing sunday.

    www.wwscc.orgI'll be there in my miata.
  10. Tuning issue I cant figure out.

    First off my profile is up to date.This issue has been going on for a while now, but originally I didn't care, I just did what I had to to make every thing work. The issue I'm talking about is I seem to have to set my fuel tables really rich to get my desired afr. Late last year I decided to...
  11. 1g AWD autocross setup questions

    Or X/Prepared
  12. could this be from welded center diff+street car?

    You are getting much more torque to the rear wheels with the welded diff, then you were with the stock viscous diff. Also you don't have any suspension mods listed, if you are still on your stock suspension you are transferring alot of weight the rear end of the car putting even more stress on...
  13. Front swaybar help

    On 1g's the front sway bar reduces understeer becuase of our crappy camber curve.
  14. brian crower 272s who running them?

    I also ordered a set, should be on the way here. I compared them to the fp2s, they have slightly less lift, same duration, and the exhaust cam is retarded slightly. I hand drew in the BC specs on the fp2 spec sheet. I think that the retarded exhaust cam will help out with midrange power with...
  15. Front swaybar help

    Your going to want to reinstall the stock front bar. My directions are long gone, I did the install 2-3 years ago. From what I remember there are two large subframe bolts that you have to remove to mount the bushing mounts for the the ST bar. You bolt the bar to these brackets. Next you have to...
  16. Publishing my Autocross Secrets

    Thanks for the update, I've got a couple of questions.For those of us that don't have scales or access to scales. If you set your ride height to match left to right with the drivers weight, does this get you in the ballpark? For example with 240 pounds of weight in the drivers seat of my...
  17. Front swaybar help

    You are supposed to run both bars.
  18. Publishing my Autocross Secrets

    AWD's have the rear subframe from the all wheel steer gvr4. But when they put them in the dsm's they removed the steering rack, but they didn't do anything to keep the wheels from self steering, which they do and turn the opposite of what would be benificial. There used to be a good write up of...
  19. Publishing my Autocross Secrets

    I dought it blows as bad as the awd rear suspension. And yes I agree agx's blow, I hate mine.
  20. Publishing my Autocross Secrets

    Just out of curiosity, what are the 2g motion ratios?
  21. Publishing my Autocross Secrets

    Shocks are a huge factor, my miata is 500/335 and rides better than stock, and thats on a car a 1000 pounds less than a dsm. But I have shocks that are matched, one of the sets DG doesn't like.
  22. Publishing my Autocross Secrets

    Yep.I think that the front is probably the same, but I suspect the rear is probably different unless they used the same rear suspention setup on your fwd.
  23. Publishing my Autocross Secrets

    I haven't measured for myself but I read on this forum a long time ago that the motion ratios are front .92 and rear .84. I have no clue what the typical corner weights are though.
  24. FMIC w/1990 Oil Cooler

    It wasn't an issue on mine, the power steering cooler was though.
  25. Publishing my Autocross Secrets

    First I want to say thanks for publishing this.I have a few questions:Do these methods apply to all cars or just 2g's? I autoX a 1g awd and a miata.Is natural frequecy the same as bounce frequecy?You say to start at 65% critical on shock valving. How do you determin this number? Does it...
  26. Is kumho gonna make a 245/45/16 v710?

    Actually I was asking if you knew if kumho was ever going to make that size. I heard they were last year but they never did.
  27. Is kumho gonna make a 245/45/16 v710?

    What about 245/40/17 V710. I'm using 245/45/17 victoracers, not as sticky as 710's and too tall.
  28. 2.3 problems- never ran right under boost

    I think the lean spikes are caused by your injector duty cycles dropping. I don't know whats causing the duty cycle to drop, maybe a bad maf or a tuning issue.
  29. Holset HX-35 Oiling

    The one I got was different, it looked like it came blocked and then had a hole drilled in it. I got it from joeracer321, its discussed in this thread starting at post #255. http://www.dsmtuners.com/forums/showthread.php?p=1819736#post1819736
  30. Holset HX-35 Oiling

    You need a restrictor. Holset specs 50 or 60 max psi if I remeber corectly. My hx35 only lasted about a month with out it. I bought one from one of the vendors on this forum. I don't remember which one, he is in one of the long holset threads.
  31. Something is slipping.

    I pulled the clutch out, nothing is broken, still has plenty of material on the clutch disk. Unsure of how to diagnos if its glazed or not. Heres some pics let me know what you think. I also pulled out the center lsd, I don't know if these can leak or not, but I found some clear silicon like...
  32. Something is slipping.

    I called horsepower freaks and they said it could be any of many different issue with the clutch, the center diff, the front diff, or the center lsd. When I mention that I still had the orignial lsd he said that could definiately be the problem. And the best thing to do is drop the transmission...
  33. Something is slipping.

    Did this car pass the standard lift one wheel at time and spin it test? I did this and mine passed.
  34. Something is slipping.

    I went drag racing Friday, every run something was slipping. It happened twice in second, twice in third, and once in both second and fourth. Every time it happened at gear change. I would shift gear as soon as I was back on the throttle it went straight to the rev limiter, I let up and hit the...

  37. Finially made it to the track.

    No burnt clutch smell.
  38. Finially made it to the track.

    I finially made it to a 1/4 mile track, I've been running 1/8 mile all summer. I've been running 7.2 in the 1/8. But it isn't a true 1/8, only 600 feet. So unless I'm doing my math wrong I think I should be about 7.4-7.5 in a true 1/8. So based on this I was expecting a mid to high 11 second...
  39. Max airflow?

    I got the v2.02 chip installed, retuned the maf mode back to were I was with the v1.3 chip. Logged a run, it was the same as the ones I was getting with v1.3. I then switched it to RPM mode turned 6500rpm up 10%. Made another run and the log looked the same as all the others I've done. For some...
  40. What lb/min are you flowing on pump & bigger turbos

    This isn't true, my timing is exaclty what I have it set at in my timing table thru out the entire rpm band. No stretching and no advance over what it is supposed to be.
  41. Max airflow?

    I'm not using DSMlink, just my own custom chips. I'm trying to do the compensation with the MAFT. I was hopeing maybe there was a change in the code on the newer MAFT chips. Also maybe the having the addition of the rpm tuning mode would help.I don't know what else to do other than switch to...
  42. Max airflow?

    I asked this question on an autoX email list I belong to, I got a response from a guy who did some research on it and asked around. He said that a trusted source told him that"Maximum allowable value for gm/sec is 512. But a 3" MAF will max out at about low 400's. "I also found on an LT1...
  43. What lb/min are you flowing on pump & bigger turbos

    47+lb/min on an HX35 on pump gas.I say 47+ becuase I hit this at 25psi, and when I run 30psi I still run the same max number, I however hit 47lb/min at a lower rpm at 30psi than I do at 25psi. I think something is keeping my maf from reading higher than 47, I haven't figured it out yet.
  44. What lb/min are you flowing on pump & bigger turbos

    Log grams per rev, multiply by rpm to get grams per minute, then multiply by .00221 to convert from grams to lbs.
  45. Max airflow?

    I just found a site that listed max airflow, 719cfm. http://dtcc.cz28.com/flow/index.htmNothing on max accurate reading yet.
  46. Max airflow?

    Does anyone know the max airflow that a 3" GM MAF can accurately read?I've searched here and found nothing, I searched google and could only find info on the 3.5" MAF.
  47. Forge BOV

    I just swapped in the 15-23psi spring. All the surge(flutter) is gone except for part throttle at 12-15psi range. I was reading some of the threads on the greddy BOV's and how to adjust the preload, I'm assuming this is the equivilant to changing springs in the Forge BOV's. And the consensus...
  48. Huge boost leak

    I had it hooked up before the throttle body and after the intercooler, it pressurized but leaked at the throttle body seals and injector seals. The huge leak that prevents me from pressurizing the system is befor that.
  49. Forge BOV

    Well I got it installed, it leaked so I JB welded it. I got the non recirculating valve, it came with the tuning kit and I installed the the 23psi-30psi spring with no shims. It holds fine, when I let off after full throttle it has a loud pshhhhhh, that last for kind of a long time. Then it...
