Hey Rob @ TSM, I have a thread on here about the VQ making 400whp, do you think it is possible on a NA set up?

.

Good luck with 2.55 ID on the OEM TB....

the inlet wall at mid-way from the butterfly and the entry is quite thin and I doubt very much its feasible or safe !!

cant wait to see your own result !

I've read both Jun and Mines bore theirs to 62mm. Will be interesting if Maxbore can do 65mm.

I only make 304 to (309 RWHP best pull) SAE with bolt ons and 4.08 gears and its a 7 AT.
with motordye 360 intake. it made 2 RWHP more than the stock intake
94 octane
114.7 is my best trap
12.343 best time.
based line was 264 rwhp.
I wish that it could have 360 + rwhp.
the dyno was a dyno jet. elevation 312 ft.
I think that your RWHP #'s are way too high.

I'm just going off Maxbore. Maybe he's never done one, maybe he's done a lot. Time will tell.

the lower you FD gear is, the lower the whp is shown on the dynojet Vs the normal 3.7 stock.
then you probably mean the 350z HR intake ? with its longer intake runner , it wont make more than the VHR intake, this is irrelevant to the higher result from other shop that claim 340+whp

and that 12.343 1/4 was with some uber slick tire. which isn't the usual tire that the average people do...

but I agree it seem like our dyno read quite low VS some of the US one ..
your baseline was 264 whp on a dynojet and mine was 254whp at APH and then 256whp on a dynapack (SG-motorsport now Onpointdyno) I used after each mod... a gain of 68whp on the same dyno before I blew it on the track.

I would love to test my new setup on a VVEL engine!! but will see how much my HR get over them first

Well even at 62mm in the middle, OEM at its smallest is only 59.8mm. So its something. My biggest issue is getting the back at 2.39" to 2.5" where there's lots of material from the looks. I just want that connection port matched to the manifolds size.

yea 4.08 swap isn't too bad just takes a bit of time and money.....and searching for a MT pumpkin to swap in pretty much from what i understand.

too be honest i wouldnt do a swap. maybe if i got really annoyed with not being high enough on the 14/ mile et list and wanted to improve my time. also i could probably drop my time with a better LSD. the stock one is good but has it's limitations.

Good to see you.

"Hey guys, look how good my 1/4 mile time was. Disregard the fact it involved killing the car."

After seeing two dyno results from different shops/dynos/day for my car and having a 20whp difference I don't see them as an accurate tool for measuring. They are just an essential tool for tuning imo.

Z eliminator · 05-20-2014, 10:40 AM

The car was " killed " by the uprev RPM limiter setting "
it was set for 8100. and during the burn out it hit 8500 rpm,. I did not react fast enough to the rpm. and it took out the oil pump or the timing chains tensioners in the driver side head.
No idea why it let it hit that rpm.

Right. So you volunteered for a blown motor with that raised redline. Bravo. Got that GTM motor yet?
