The Dynapack in the article seems to be measuring or calculating horsepower and torque at the flywheel. I'm not sure what's up with that. I don't know much about DynaPack dynos. It would be nice if they tested the engine on a DynoJet so we all could relate.

There really is no secret though. The BC stroker kit is very expensive and its installation is more complicated and expensive that assembling a normal VQ35 engine. I thought about getting one but didn't want sleeves and didn't want to spend the extra money on the stroker kit.

This is the first NA stroker kit anyone has built. There isn't much other information available on that combination. Time will tell...
all dynpack charts show hp as crank - for whatever reason, that's just how their charts read, but it is measuring hp output at the hub that is bolted to the dyno. It also depends what their calibration is set to, as you can have the dyno read high, or low. I know on my last run on a Dynpack, at Turbo XS, I put down 320 whp. Their dyno is setup to read exactly like AAM's Dynojet, which is literally down the block, so it's safe to assume I'd put down right around 320 whp on an average Dynojet as well. As for this car specifically, who knows, not really alot of info listed there in terms of what the engine has, but nice build for sure

a drag race ain't gonna happen with me, sorry...there are none nearby where I am located (over 2 hours away to the closest one to me, and these guys are located even farther). Not to mention, I just don't care who's is "faster". I am happy with mine, as I am sure they are happy with theirs

To the OP - if you're buying a car with a legit 376 whp, and all it has is an intake an exhaust, then you're not buying a Z. If the car has a legit 376 whp, regardless of what is done to it, I'd want to see a dyno sheet proving that it's making the power that is being claimed.

unless you find me a stock G with 275Hp at the wheels, that hp reading in the article is rated at the crank. So calculating 15% drivetrain loss, it's making about 320 at the wheels with the stroker.

that's a good point now that I am looking at the baseline. Problem is there really are no details as to what the car had before and what exactly it has now

the sad part is it doesn't matter. what could it possiblly be running on before the stroker to make 275 at the wheels? making 100 more hp on a already tuned engine from NA stroker parts?
Pushing that kind of horsepower NA with just a stroker install is extremely difficult if not impossible.

I think the forum already have examples with yours (Z1) included of what the limit looks like with a NA setup.

hmmmm... his "friends" Z probably has the whole (dealership) NISMO catalog thrown at it! intake, headers, HFCs, exhuast, cams, oil cap, etc, etc. And he just used the NISMO HP stacking method for around 375 at the flywheel...


LOL!

Why is 370 crank horsepower a stretch for a bored and stroked engine?

Actually I did read the thread title...

and...

I read the posts after the original title... If you'd bothered to read the posts in the thread you'd see that people have been talking about the true intent of the article that this thread is about.

Go back to your four bangers, Honda-Boy...

what? that made no sense. nobody is saying that 370 CHP is out of range.

PS: id go back to my four bangers if i had:
1) ever owned a honda
2) ever owned a four banger

yeah, i guess a vq35de makes you a honda boy...

BTW, i consistently run faster at the strip than all the NA z's there, so theyre all being beaten by an almost honda. makes you proud huh?

bring it to Fontana... if you consistantly beat NA Zs, then you certainly can beat an AT G sedan (or can you? - not likely this one).

No time slip? Yeah, that's what I thought.

Look honda boy, go brag about it on some maxima/ honda forum. Maybe they would actually care. In case you didn't realize, this forum is for Zs and Gs, not FWD maximas. If you want a Z or G so bad, then step up, be a man, and just go buy one and quit being such a wannabe punk. Lol.

not everyone wants a car that only seats two, or can afford one being in school and all. its funny though, you act like a BMW fegg, but the truth is that the majority of the population would take a maxima over a z. why? people need a DD that is reasonable. considering that the maxima has the same engine and basic driveline (just WRD instead of RWD), its a good choice.

BTW, i am on a maxima forum, theres good info there too, just like here. that is why im here. however, my ignore list just grew 1 spot. i dont have room in my day for ignorant people that think they are better cause they drive a z. and why dont i see you on the top 25 list for anything?

soooo, its not a normal NA g? or are you just a better driver than every z/g that goes to this track? my dad drives a G sedan (A/T) and i hate driving it cause its anemically slow compared to my car. Then again, i do trap 104 so

Tuned with an e-manage, all the money for a stroker and use a cheap ems
the dyno readouts show "flywheel horsepower." I wonder what their correction factor is?
