I know I read an artice that someone posted that stated what the internals of the engine are rated at but I cannot seem to find it....
I SHOULD HAVE SAVED IT ](*,)
I think it was like 160HP or something, but i dont know if thats at the wheels, crank, flywheel..... blah blah. Or is it more?
SO what is the most the internals and Transmission can handle?
I contacted a speed shop in my town through email that does fabrication work and all kinds of stuff and I should probably know this...
last i heard it was like 150 or 160 flywheel hp
tranny i have no clue on
f16 tranny.... assumed 160 torque.
Yeah, seams to be follow the tread of the # having to do with the tq handling capacity. As an example, we have a zuki memeber that went through two D20s, one with 245whtq, and the other he had 200whp (tad bit more tq) and blew the tranny when he had a rare boost spike.Quote:

okay so its 160 hp at the flywheel for the engine and 160 torque for the tranny... If i get the engine to 150HP at the fly and 150 torque, I should be okay with reliability and stuff... or would it be a good idea to upgrade internals at that point?
You'd be getting close to the limit. Even if you are careful.
have an extra tranny on hand
If i were you i would try to find the best way to keep the torque down a little if you can get 150hp and like 140tq or i think you would be safer
and it really depends what your doing with the car. Also in this n/a or forced?Quote:

Torque is what kills trannys though and shifting too late also does it...if you shift up and it throws you in the back of your seat and you feel much more power than right before you shifted, you're probably shifting too late
And so does heatQuote:

:roll: this thread is just a guessing game...you can't really know till you tune and dyno it...ive seen plenty of the same setups run totally different number, including stock engines
I believe I'm gonna be N/A... Thats the Plan as of right now atleast.
What kinds of power you think some middle profile cams, race headers, 2" exhaust, 10.5:1 pistons, CAI and a tune would bring me? Also to get a bit more power to the ground it's be stiffening up things and lighter wheels, etc...
any other ideas/suggestions?
:edit:
after reading sams post....
well whats some numbers you guys have seen with a setup like that?
From Daewootech reguarding the D16 Transmission.

hey
did i read soemwhere that you have 240HP and 300Nm and that you have a D16 manual transmission?
300Nm equals about 222 ft-lbs of tQ, right?
if this is true, did you do anything to the transmission or is it stock?
and have you had any problems?

Around that... I didn't have this confirmed... I did confirm on MAHA dyno-brake with 40HP NOS shoot, 211HP and 257Nm... With 70HP, it would be around 240HP and 300Nm... So yes...
D16 is stock...
Thats A LOT more than 160 Ft/Lbs of tQ.
Aveosam is probably right... its all a guessing game. But 160-240 is a huge difference.
It is a huge difference. But I bet my D20 trans would stand up to a couple 300 wtq dyno pulls before it breaks. When my other ones broke, it was right away, it took time and driving around boosting before anything happened. It seems the metal eventually fatigues and gives out.Quote:

So it looks like what he's doing falls into the 160 ft/lbs of torque just as we have been thinking. There is probably bad wear from him pushing 220 ft/lbs though.
Thats the one of highest torque rating ive seen, I just pm'd someone with 275 whp and 237 ft lbs torque also. I'll post what he tells me.
the guy with 275 whp and 237 ft lbs torque was running an F18 transmission... so not a d16
That's still allot thoughQuote:

people have been pushing our engines at like close to 200hp, but they swapped transmissions. so really the only thing holding us back is the tranny.
A d20 isn't all that hard to come by, I know of three locally with under 10k miles for $600 and you can probably get them to come down some since they don't sell all that fast.
yeah i plan on getting a D20, either when i turbo... or slightly after.Quote:
