So let's see here, you can't spell the word you chose as your screen name, you drive a lame FWD car, the only mods in said car is a stereo system, and you try to post like you have a clue, which you obviously don't. Ok then, as long as everyone is on the same page I guess we can move along.

Never say another word about the quad 4. Do 5 minutes of research and tell me that engine isn't STILL to this day a bad mother ****er when modded. They run those destroked to 2.0's all the time for 2.0 class and take a beating. They got a world of aftermarket going still.

Or better yet, look up Jim Feuling who built a 750hp twin-turbo quad 4 spinning 9500 rpm's for the Oldsmobile Aerotech back in ****ing 1988. Find me an import 4 cylinder doing that, and I'll shut up. Til then, YOU stfu

**** that I'll do it for you... here's a clipping from his wikipedia:

"In 1988 he received the "Outstanding Technical Achievement Award" from the National Engineering Societies for his "clean sheet" design, development and manufacture of the 2.0L Oldsmobile "BE" Quad-4 racing engine used in the Oldsmobile Aerotech Research Vehicle (267.339 mph International Record, driven by A. J. Foyt). His radical design for the Oldsmobile BE 4-cylinder engine developed the highest specific power output of any automotive engine in history (over 1,270 hp from 121 cubic inches)."

the 3.4 did need a little redesigning...it was kinda thrown together too fast...its still a sweet motor when done right..


guy in colorado has a 160k mile 3.4 w/ a turbo at 10 psi and totally stock tune putting 325 HP to the wheels.....the 3.4 heads flow like crazy stock.

i wouldnt say gm ohc engines suck at all, it comes down to "you get out what yo put in" if you hot rod it around its going to wear more...

[MadmaX]

oh come on man, that thing was a turd. they leaked and burned everywhere. high mileage examples where the exception, not the rule.

at least the timing belt was easy to change. and the chain wasn't much worse.

[rsisbetter]

oh im not disagreeing, if driven conservatively, and maintained they can last like any other engine. one of the gheyest disadvantages of the 3.4dohc was that the tb was part of the plenum, ghey.

[MadmaX]

why was that a disadvantage? or matter at all?

[rsisbetter]

replacing stock tb, with a larger one. the stock plenum can only be bored out so far, i think they're like, 56mm stock. eventually cfm air flow, from the limiting plenum tb will take effect. but thats just one perf. type of reason.

do you have the internet?

and last i heard cast rods are not as good as forged.

both bmw and gm use them in some motors.

ecotecs with built rotating assemblys have great potential but so is any motor that has a head with good flow numbers. just wondering has there been an ecotec that has ran in the 9s with 150 traps on stock rotating assembly?

and bmw formula one motors from the infamous turbo formula one era were not even competitive. honda won 4 consecutive engine manufacturer championships from 86 to 89 winning 15 of 16 races in the last season of turbo motors in f1.

huh?

After 22 years in production, a m10 won formula 1 in 1983. Honda's are fine, but BMW was taking used m10 engine blocks and putting them into service because they found the heat-cycled metal was stronger, and my point is they where basing their race motors on engines that were not only like the engines in their passenger cars, they had literally been pulled from them.
Educate me, did Honda do something badass like that?

whats the point of doing something like that if you arent competitive. I could care less if they were using the oem short block, cause they were not using the oem rotating assembly. stephanie eggum ran 7s on the oem honda short block, its not an accomplishment. although there have been multiple stock/oem rotating assembly hondas that have ran 9s at 150 plus and have ran them for multiple seasons in pro am. bmws are good too, im just talking about superiority in f1 in the turbo era. now honda sucks in f1.

anyways the idea of a seasoned block is not a new one, although when someone refers to a seasoned block it is usually in reference to main clerances and not metallurgy. speaking of metalurgy the C30 and C32 have titanium connecting rods, although its titanium content is still less than an aftermarket titanium rod and the B18C1 has forged steel connecting rods with a steel alloy that has a high chromium and high carbon content which is quite similar to 4340 but lacks the nickel content.

uhhhhh are you serious?


http://www.formula1.com/results/team/1983/

maybe you meant won a race.

fyi drivers and manufacturers championships are two different things.

thats why i dont trust wikipedia.

[MadmaX]

I stand corrected, 3rd and 14th.

how much shorter is the service life of the C30 and C32 connecting rods? typical titanium or better due to a lower content?

[TurboB18C1DC2]

I stand corrected, 3rd and 14th.

well since the rods are such a low titanium content they dont have the stretch problems that SOME ti and quite a few aluminum rods have. also since they are such a low content titanium they dont have the "grabbing problems" on their journals that aftermarket titanium rods SOMETIMES do. aftermarket titanium rods can sometimes "grab" bearing surfaces depending on how the rods journals are treated.

Titanium to some extents likes to rub off with steel when they're rubbing against each other. I think this is what people will refer to as grabbing or galling. Chunks of material will transfer or get stuck from one side to another. so its critical that if you run titanium rods that you run titnanium bolts. also the rod bearing journals need to be titanium nitrided or coated with some kind of moly in order to prevent grabbing or galling on the bearings.

in terms of the nsx connecting rods the service life is normal.

[MadmaX]

if there's one honda you could catch me driving it'd be an NSX.

if there is one bmw id rock it would be an e30 m3 with its 2.3 four banger or a e36 m3. but what i would really rock the **** out of is a 1990 evolution III m3 with the 2.5 liter, but I think those never made it to the states

[MadmaX]

they seem like totally different cars to me. Like a CRX vs. a Prelude.

That would be wicked.


I'm very close to being ready to boost my SuperETA.

Megasquirt's workin' good, I've got a turbo, injectors, downpipe. I basically need the manifold adapter($350) and some oil lines and I'm ready to go.

oh yeah it was a sweet car. the super eta is that the low redline tq monster ones with i am assuming ginormous stroke.

[MadmaX]

There's the normal ETA; Yes, extra stroke, big torque, no revs.

The super ETA was made for one year; BMW took the 325i motor and made an ETA out of it by increasing cc's, using just single valvesprings, low-rpm cam, and tiny runners on the manifolds. The result was the same torque as the normal ETA and 6 extra hp.
Big deal.

What's good about it is; that you can put the high-rpm cam, double valvesprings, and bigger manifolds back on it, keep the extra displacement, and have something with more h.p. than the 325i motor and more torque than the ETA.
I do not know why BMW never offered this at the factory. There's no downside. You basically get a 2.7 liter 325i motor using oem parts.

Mine dyno'd 110hp/135lbs of torque to the tires, stock. Which is about right since it's rated at 127hp/170lbs torque at the crank by bmw.

After the aformentioned hybridization, I put down 155hp/165lbs of torque.

to be honest with you thats not bad. reminds me of prelude mikes old h23 that dynoed like 160hp and like 155 tq. your bmw is probably pretty fun on the street.

when you dynoed were you at dynosport and was bmw jim helping you with the car and where you running megasquirt at that time. if so a very good friend of mine named will told me about your car. i think you dynoed at night, at least thats when will stopped by my house.

yeah. That was the night I was all pissed 'cause I lost power switching to m.s. The factory motronic was still controlling spark, but without any inputs, it won't leave base timing. It's kinda hard to make power on base timing no matter what you're doing with fuel.

I'm sure there were tons of 750hp turbocharged I4's in Japan in the '80s. You just might not hear much about them because a lot of those guys were very secretive. Wangan racing ftmfw!

And I know of a tube chassis car with a turbo I4 from the 80's that puts down 700+whp and runs like 7s.

Oh, and timing is very important on a diesel.

Martin

[MadmaX]

Alright, so;

1st visit to the dyno....Motronic is doing an okay-ish job with fuel, but is advancing ignition as far ahead as possible on 92 octane.
2nd visit to the dyno...Being able to tune fuel with Megasquirt nets a smoother and more desirable A/F ratio, but Motronic was not doing a bad enough job with fuel to begin with. Whatever advantage there may be, doesn't make up for the disadvantage of spark now being locked at 10degrees.

Do you have a problem with THAT statement Martin?

[82355]

No, none at all.

Martin

[82355]

Do you have a distributor on that?

Martin

[MadmaX]

Yes, unfortunately there's no jacking with it. The rotor is bolted to the end of the OHC, and the cap screws directly to the timing belt cover.
