i just got the car running good, i had some code issues but i finally solved them. last night the boys decided to do some runs and i came out with my camera to catch some vids. after the run which was two supras a 7M and a regular one, everybody decided to roll to a different location. i was in the back of hte crew filming with the camera in one hand while i drove with the other. were are moving pretty quick so i go to put the camera down and knocked the tranny into 2nd gear while accelerating i banged of the rev at about 8,000 rpm i believe and the car bucked hard. i have the jwt 7200 rev limiter so that didnt help either. the car rides very sluggish so i do a compression test and have almost no compression in a couple cylinders so thats that. this makes three different ways i have blown my motor in several months. the first one was detonating from running a high dry shot, the second was running hard and hot causing my crank pulley to overheat and snap and now this. im gonna take the car apart and see exactly how bad the damage is and take it from there.

 

The rev limiter would stop you from revving your engine over 7200... However it won't help if you put it in the wrong gear...

 

damn. that sucks man. 8k is high for a max? but how did u get past your 7200 rev limiter and all the wya to 8k? and how many shots u running?

 

The tranny shouldn't downshift if it's not within the correct RPM range.
And how is it possible to overheat and snap the crank pulley? Belt friction?

Those things just don't sound right.

 

That's a number one reason why I do not mess with my engine cuz I don't want to deal with some mechanical failure. Stillenmax, i noticed your profile say you have a Skyline, that's really sweet but how did you manage to afford one since it probably putting a hole on your wallet.

 

wow you must dont know c max. he has a monster and i was there on two occassions when he blew. in springvalley with me meccanoble and liquidvenom and others, c max was roasting everything out there including mecca with 11lbs of boost. he was running a stage 2 neon turbo and after he won the car shut off. his timing chain slipped from his crank failing. and on this one we were coming from a run when his car just revved high and i heard a popping noise and he shut down. i asked himwhat happened and he said he knocked the gear into 2nd. he wasnt even running that night until he put his nitrous solenoid in, just a freak accident.

 

don't you have an Auto? How in the world did the tranny downshift itself in an Automatic? I've done it in my 5 speed and hit 9800 rpms monitored by the defi recordable guages. Needless to say that motor didn't last either, the BOV went completely retarded when it happened.

 

It's hard to knock it into 2nd accidently. Especially considering you have to push the button on the shifter to do it...

 

Thats what I was thinking but I thought the ECU wouldn't allow the Auto to downshift past a certain RPM/Speed.

 

I wish it wasnt so but it happened. i was filming a run with my right hand while i drove. first let me back it up some, i posted about issues with my tranny after my last rebuild the tranny would go into gear without touching the brake or button. some told me it was my cable that had to be adjusted but i never really figured it out. anyway while im filming the guys really start to haul so as im starting to accelarate i go to put the camera down and bang the shifter into second and yes its a auto. i didnt reralize it was in second while i hammered the gas peddle and until the car bogged, did i realize what happened but it was too late. this is clearly stupidity on my part and i have to take it as it comes but this is what happened. i wasnt even running the nitrous due to a bad fuel solenoid that i had ordered sat and was hoping to be back up and racing by next week at the track. the car is going into the shop in the next day or two to see exactly what i damaged. maxboogie i didnt see all of the race but i heard my boy got whupped pretty bad.

 

i was only doing about thirty miles and hour before i started to accelerate either the car slipped into second before or during but all i know is i slammed that rev limiter when i stepped down then it wouldnt go past 35 mph.

 

it was awful cmax he got beat bad.a cmax didnt the same thing happened when you raced mecca . i remember yall running from a roll and the same thing happened. i wasn't that far behind you when it happened. all i saw was you pull crazy on that evo that was next to you then shut down.hit me up on the dc and let me know the outcome.

 

huh? at 35mph your car should be no where near the rev limiter in 2nd gear....

 

Yeah, you went into first. Still, first will bring you up to 40+ no problem. I don't understand this. The TCM will no downshift if the revs are too high. Even if the shifter is moved. I've done that several times on accident. I dropped the shifter to first doing about 120 and nothing happened.

 

please guys read my post. im not here to argue about what happened it happened. my car was able to go into 2nd for two reasons i was only doing thirty before i nailed it and i have a level ten tranny which i always was able to downshift at higher revs just not bang on it like i did this time. if you guys were right then i wouldnt have this problem would i. i didnt make this up, its not a fairy tale it happened plain and simple (i wish it didnt). if you would of heard the motor at that speed you would know what im talking about it wasnt a pretty sound. but either way the car would be dismantled tommorow and repaired, then the tranny will be fixed properly to avoid this in the future im sure im not the only one this has happened to. p.s broaner remember im dealing with a good amount of hp and modifications that allow my car to move into the higherbands when i hit the rev limiter its snappy fast not slow so it bangs very hard when it hits.

 

Im not saying it didn't happen, but at 35mph 2nd gear wouldn't even be near 5k rpms much less 8k...Even 1st gear at 35mph wouldnt be anywhere near 8k rpms more like 6200ish....

 

do you realize im boosted so banging off the rev is very hard and i continued because i didnt realize it wasnt going to shift so imagine me at 7,200 bouncing off continuosly with 9lbs of boost, not pretty.

 

Im boosted (12psi) too man and I've over revved mine too 9800 rpms data logged, but Im also a manual and I shifted from redline in 3rd 7200 back to 2nd. You're saying you where going only 35mph when it happened I just want to know how you where hitting any rev limiter at 35mph thats all. If it shifted back to first somehow and you floored it it might have hit the rev limiter after about 45mph or so but it wouldn't have revved past 7200rpms. What you are saying doesn't make any sense to me...

 

sorry to hear that man.... its happened to me once before. i was going about 90mph and hit 2nd and it shoot to about 7800rpm. But everything has been ok since.

 

o.k let me explain another way. before i hit the gas i was cruising at about 35mph i hit the gas thinking i was in drive and flawed it to catch up to the crowd. now mind you i had my 3000 watt stereo bumping the new 50 cent album while recording and didnt know the car was in second when it reached red line i continued flawing thinking it was gonna shift, now a couple secs could have past while its hitting the redline. my friendsd said they heard a pop noise but i didnt. when i realized what was going on the car was very sluggish after that. i dont know how to explain it any better except thats the way it happened. it also happened while racing mecca the same exact thing except nothing happened at theat moment but 30 mins later the chain broke so maybe it did damage then too. i have run aas high as 14lbs and a 100 shot of nitrous and it never happened before either so i dont know.

 

I think you need to clarify a little...Is this what happened???
When you went to accelerate, and you knocked the shifter into second at 35, the rpm's were not that high when you actually knocked it it. Instead, you didn't realize it when it happened, and accelerated like you would had you been in drive, expecting a shift at 7200 rpms, and in turn bounced rev limiter?
Most everyone here thinks that you dropped second, and instantaneously bounced rev in second gear, which is why everyone is confused. I'm just trying to get the story straight.

 

i was a little confused also because i dont know when it actually got knocked into second. but yes thats basically right i was accelerating probably in second thinking it was gonna change gears but it didnt i kept on accelerating anyway as it continued to bang off the limiter maybe at 60 plus miles an hour. come on guys you know me theres no need to b.s, this has got me stumped too and im trying to figure out how to avoid it not prove that it happened

 

You guys are something else.

 

I wasn't trying to give you a hard time, I was just trying to clarify the story a little bit, cause when I read through, it seemed there was a lot of confusion...
Good luck with it though

 

after reading your last reply it sounds like you knocked it in 2nd and didnt realize it and you sat and bounced off the rev limiter in 2nd for a while.
Doing this caused the tranny to heat way up and destroy itself. If you where bouncing off the rev limiter in 2nd gear in an Auto it would have been well over 80mph at 7200rpms.

 

i cant quote the exact speed but it was maxed out what ever it is. when i looked down the shifter was in second and i backed off the gas, when i put it in drive it started bogging down and wouldnt go faster. i have a modified level ten tranny so i hope it held up thats another issue after the motor gets fixed. its still confusing to me becasue i thought i just blew a air gasket or something just to find out the motors toast. well thanks for giving your input and hopefully i'll be back on the road soon

 

Well I hope you get it all figured out and its not too costly of a repair. I've got a fubared motor now also, this weekend it decided to eat a couple MEVI screws...

 

yea i was there when your car took a crap the last time...this is why im scurred to put any more cash into my car. first your car then meccas then yours again. damn.

 

hey whats up liqid, yeh shes down again it never ends with me but thats life in the boosted world. i drove it to the shop this morning about 45 mins away i got it up to about 60 smoothly its just at idle it runs rough like its gonna shut off. the tranny seemed fine shifted with no problems so i might have got lucky with that. there gonna take it apart today and predicted 4 days to complete. im gonna have everything checked including tranny so this doesnt happen again. at least let me blow doing 11 secs in the 1/4 spraying a 100 shot, that i can live with but not nonsense like this. blubyu is the motor fixable and are you gonna keep the mevi on, dang that bites.

 

Its fixable but its cheaper just to swap a new motor in than replace all the parts new. I don't plan to do anything until I get a built 3.5 bottom end to swap in. I've decided to keep the MEVI on and I removed all the butterflies so it doesn't have a chance to happen again. Low end will suffer a tad but the big end will be a little better. Can't wait to have a little more displacement to push the T-trim blower a little harder...

 

yeh i have the t trim also a nice blower. im gonna get the top rebuilt since i have a built bottom end already unless i get some bad news that the block is damaged also. i think there will be a break in period again but after that im off to the tracks. im not looking for a mardigras just some decent runs. good luck and hope your back up soon.

 

When did you get the T-trim? I wasn't aware anyone had it but i30krab and myself.

From the sounds of what you did, I would guess you bent a few valves...

 

i got my first brand new V1 in 1996 then i brought a brand new V2 in jan 2004 then i blew it with the motor a month later running 14lbs and 100 shot i over spinned the blower. so dean doan and steve came up with a solution because they had me wait three months to tell me the s/c was damaged when they had promised me one week downtime because the car was in the shop.now since the s/c was under warranty they agreed if i paid for the t trim blades they would install for free what ever the difference was since i was running nitrous this seemed the best solution. i have spent thousands of dollars with these guys and are on a first name basis with steve and the co. i get everything at cost and dont pay shipping for my loyalty and for promoting there products. a lot of people dont know but i was running low 12's with a automatic for many yrs. there are a few posts of this subject if you can search that tells the story better but thats it. this is my site if you havent checked it out. http://members.cardomain/whoamax
