400 whp on N/A VQ possible?

Elmo370z · 05-14-2014, 02:57 PM

I'm wondering if anyone out there can tune the VQ motor on pump gas, and without the use of crazy expensive ITB's or swapping out crankshafts to make 400 whp on the NA motor? Or is the vvel that complicated that no tuners can come close to making the power without the use of DE heads, crazy engine rebuild, or forced induction. Maybe with EcuTek and their claim to be superior to Uprev, still waiting to see that. I just want some educated guesses on what they think is possible, I know tuning the VQ motor is still very brand new and tuners have come along way.

Thank you everyone for your time.

Nope. Not without significant internal work. The record is 360ish and that's on E85.

By the time your done spending all the money to make it a 400whp NA block, you could have made this a 600whp FI block.

No. Not even close.

VVEL is not black magic.

Seems NOOBish to me? DE, HR, VHR whatever NONE of the VQ motors will come close to 400 wheel NA without doing at least a couple of those thingsand you wouldn't even come close with DE heads. If you had crazy money in it you would be lucky to break 400whp now 400bhp is very possible but not at the wheels

also the grand am cars have a little over 400 but you would vommit at the price tag

Eclipz · 05-14-2014, 06:03 PM

DE heads with aggressive cams can get you close, plus all the bolt-ons ofcourse.

1slow370 · 05-14-2014, 06:17 PM

HR heads not DE, the DE heads suck. and the cams you need aren't even listed for sale on JWT's website because you have to machine the the heads to clear the lobes and change out ALL the valvetrain parts, you will also need different pistons with larger valve reliefs to clear the massive lift, and then you will need bad *** headers and and intake (ITB's or custom) to get the airflow in and out that the cams can support and a different ECU because the factory one can't handle that much cam at idle or itb's for that matter.

Just to clarify a DE with cams that don't require valvetrain modifications and bolt ons wont even make 300whp

Sooo yes vvel is black magic because full bolt ons and cams on a de will get you 60+ hp LESS than the current highest hp NA 370 which has bolt ons and tune and makes 360wheel.

Eclipz · 05-14-2014, 06:19 PM

And all of that translates into a car that will suck to drive on the road

Very interesting. @ Jm auto racing, its just something about a high revving all motor engine. Don't get me wrong boost is something magical. Thanks all for responding, guess 400 to the wheels will be upwards battle.

Jordo! · 05-15-2014, 03:29 AM

No.

And if it could, you'd need to build it to rev to 15K RPM...

So, if you dropped 15-20k on a NA build to just barely hit 400whp to have a high-compression motor that needed higher octane than pump gas and had a very narrow powerband so you'd actually be slower in 95% of real world driving situations than a 330whp car with more area under the curve, you'd be happy with that? If you're really serious, go read Shamu's build thread. He'll probably be around 400whp, but he's now got a 4.0 dry sump motor that won't be on pump gas.

For 400whp, go buy a Stillen kit and be happy. 400whp NA isn't an uphill battle. A 400whp NA car is a fool's project. You'll end up with an undriveable mess. For power on this platform you need boost.

black_sedan · 05-15-2014, 05:47 PM

A high compression built vq would be nice. Or course it would take a built bottom end, ported heads, cams but it would be badass to have a 370z that could run like the Porsche gt3

Elmo370z · 05-15-2014, 10:53 PM

I don't think you need 15k to make 400 whp on a NA build. Now there isn't to much information out there about the JUN cams; full bolt on's that cam and a great tuner could come close to the 400 mark, don't you think? Noone out there with money to play with has even attempted to try and build the car a VQ motor to make 400 whp (NA), "MOST" everyone here in the states wants power fast so they go with F.I. Anyone have any information on the tuners in Japan or do they not like releasing that kind of information out?

Eclipz · 05-15-2014, 11:06 PM

With a 400 hp na build you will probably end up increasing the red line and end up increasing idling rpm which is not good for daily driving

That's what I was afraid of hearing. the highest NA is like 340-350 on pump gas, I just believe that you can squeeze 50 more whp without sacrificing drivability. Wouldn't you agree?
