Gonna be without the car for a while...

[triflowm5]

Spun the #3, #5 Crank bearings....she is going to be down for a while so I wish i could meet up this weekend or sometime soon but i dont expect to get my car back for about 2 weeks.

[JaCelica2k]

damn that sucks. Sorry to hear that.

[triflowm5]

oh well...such is life and the pursuit of power and speed

[Acilec]

Ok ok ok, Rob, how the hell did you do this?

How did you do that? Damn, Im pushing boost on a 2.5 little v6 mazda and it is holding up excellent! Damn, you must have missed a shift and over revved that bitch...My boy did that in his M3 twice. Spun the crank bearings. ther shifter on that m3 really was not suitable for really fast shifting..gated too close.


See Raul, does'nt matter what car you have..if you beat on it, it will break.

no. some cars can take more abuse than others. misshifting is not abuse, let's just say it's a mistake on the driver's part...

I could not count how many times I have missed a shift...what happened seems similar to what my friend dave did in his m3, he went from 1st-2nd, 2nd -3rd, and 3rd to 2nd! at the track...such a close shifter for a novice like him!

Ouch..must have hit like 9000rpm?!

Honestly...I still have no idea how a decent driver could EVER mis-shift. In every stick I have seen, if the car isn't supposed to be in a gear, it doesn't go in easily, you really have to jam it in there.

missing a shift in some cars can have more drastic effects than in others... such hi-performance, hi-tech egines like the 2ZZ-GE and others which pump out over 100 HP/L at the expense of giving up iron blocks and lower redlines, put a lot more stress on their internals to achive such outstanding numbers.
a 2.5L V6 putting out just 164HP stock (about 65HP / L), can get by with a more conservative redline and heavier internal components. i can already tell you that if you wanted to extract over 250 HP from such an engine and stay N/A, it's redline wouldn't be set at 7000 and the block wouldn't be made of cast iron (we can start a whole new topic on modern engine technology)... those are things you must trade to produce more power and staying N/A... i still don't consider downshifting from redline into a lower gear, abuse... that could be the topic of yet, another discussion.
and you're right, your friend probably overreved that motor to 9000 rpms... imagine what could happen to a smaller 4 cyl hitting 11000+ rpms!

The DOHC 24v Mazda engine is an All-aluminum block/heads. FWIW

And there are few peeps putting out 200whp N/A with their JDM KLZE J-spec motors and they actually have a higher Peak HP and TQ curve due to the cams.

Im putting out over 115hp AND 115TQ per litre.



When I said that I was missing shifts, it was mainly due to a broken trans mount which shifted the shift linkage out of spec.

Also, when you have a large amount of HP/TQ and you floor the car it hits redline SO FAST that you really have to be on your toes to get the shift right...it's much more difficult when you have much more power and your tires spin so fast that you hit 8000rpm in alomost 2 seconds I could easily burn-out my tires from 1st gear all the way to 4th without even revving the car up first, if I dont have my gas pedal JUST right.

[triflowm5]

actually i was accelerating and never missed a shift...the master tech thinks/knows that its an oil starvation problem, not driver error

oh well..new toys to play with and i cant do that kind of damage to the new toy.

i see... i was not aware of that... hmmm, for an older motor i would have expected it to be stronger... like the SR20's or 3SG's...

Im putting out over 115hp AND 115TQ per litre.
that's not a lot for a forced induction application these days, btw... the S2000 has been around for a while now, and it puts out over 240HP/L stock, N/A...

oic...

see above, you don't have a large amount of power for the size of your engine these days... maybe your chassis/suspension setup needs some work to better control it... a GTS can spin the tires so fast that it hits the early cut off in first due to the extreme wheel spin...

I could easily burn-out my tires from 1st gear all the way to 4th without even revving the car up first, if I dont have my gas pedal JUST right.
i could do that with my 3SGTE... i used to roast the tires from an idle start... not taking anything away from your car, but 115HP/L for a SC'ed 2.5L V6 engine is not a lot... (to quote some 2 liter 4 bangers: WRX 113.5 HP/L, STi 120HP/L?, EVO 135.5 HP/L, oh sh!t i better not quote the SRT4 as i was going to since, as advertised, it does not even break the 100HP/L mark... sorry sean! :chuckles: )

The thing is that this engine, for an older engine is highly advanced for the year it was introduced.

It is an all-aluminum engine, lightweight, and high-revving for a v6 (8000rpm) It produces just as much tq as Hp.

It also has a steel forged crank, stock.


115HP/L for a SC'ed 2.5L V6 engine is not a lot.

Thats great but lets talk about TOURQE PER LITRE.


Yes, it's true I could be putting out more but Im only boosting 6psi
and my engine is a v6 but still very small for a v6 at only 2.5 litres
Most STOCK cars these days are running 10-12psi stock.

At 10-12psi I would be putting out WELL over 320WHP! That would be good for low twelves even high 11's :AF:

Im happy at 6psi though..the car runs perfect. I have an excellent EGT and no problems whatsoever.

Im happy running 12's..thats PLENTY for me.....I can pretty much run with anything on the road with a few exceptions.

In my opinion I think I have a lot of power, I consider power Torque. Tq drives HP. Tq is what drivesme through the 1/4 mile. HP pulls me through on the end.

Considering the size/weight of my car (2600lbs) and being Front wheel drive 300hp is PLENTY not to mention 300pounds of TQ.

So your telling me that having 300Hp and 300lbs of tq is not a lot of power?

It is NOT easy to run 12's in a FWD application, and you have to have a lot of power to do it.....

Name 1 production FWD car that run 12's and Ill give you a cookie! :)


You have no clue what 300lbs of tq feels like to drive every day....it's much different than having PEAK HP at 8000rpm...Im already makig over 200ft/lbs at 3000rpm

And the 3sgte only has 200hp/200tq stock and I doubt that your motor was making even that at the time with your faulty turbo.

[NOSPGT]

a GTS can spin the tires so fast that it hits the early cut off in first due to the extreme wheel spin...

Dude, please ..you cant compare a motor with 130? pounds of tq at 7000+rpm to what i have to deal with.

I can be in THIRD gear, at 3000rpm, floor it from a roll and leave tracks all the way until 4th gear.

I HIGHLY doubt that you can do that in a GTS, even if it had Nitrous.

Im just being realistic.

All I was trying to say is that having multi-hundred pounds of TQ with FWD and weighing 2600lbs is hard to control uless you are a skilled driver.

Sure there are other cars that have 240hp and 240lbs of tq but they weight almost 1000 more pounds than my car and they have traction control to ease that..but we all know that for drag racing, leave the traction control off and learn how to drive it correctly to get the best times.
