the funny thing is I have the passport meter and its telling me with the weight entered in correctly that its making 222-227whp


also a new gto only dynoed 230whp (350 crank hp)

 

Not sure if that correlation is very accurate. I have a mustang dyno in my city and the last time I dyno'd I got 190whp and 185 lb/tq. This was with a flakey ks sensor, ts ecu, greddy sp2, budget y, hai. I doubt I would have 210+hp on a dynojet, but hey I wouldn't complain.

 

by the look on the dyno graph I think the intake manifold is killing it cause it stays pretty flat all around no spike in either

 

That's quite a bit low for a GTO isn't it? How much drivetrain loss on a rwd GTO? Dave?

 

Ill bet $5 that he's making more than 200 whp

 

We should put a 00 vi on to solve that

I would love to see a dyno of mypathy TB and 00vi on that engine

 

Im making 2 custom manifolds one with a Q45 v8 tb and another with a stock one

 

What really stands in the way for us to use the 3.5 intakes? as well as heads (i know VVC is usless with the 4thgen ECU). IIRC the 3.5 intakes mimic the VI on the 2000s and may free up alot of power.

 

The 3.5 manifolds have different ports and wont match without mods

 

I was thinking the exact same thing.

 

But if you used the 3.5 heads and some how got around the VCC (or is it VCT...) wouldnt the ports line up. I was also thinking the 00 VI as well, but also dont the 3.5 heads flow more than the 3.0?

 

I say forget the dyno and head straight to the track. It's cheaper and it will really tell us if your car is fast or not. There are quite a few quick tracks in your neck of the woods.

 

230rwhp for a GTO, even on Mustang dyno, is really low. They're putting down ~290-300whp at the Dynojet shop I go to.

 

like i said, it is going to the track on the 25th.

 

after almost 2 weeks its still running strong and gettin 20-21mpg. I had one check engine (cylinder 1 misfire) im assuming is due to rough idle cause it came on while at idle for like ten min.

 

hope evrything is alright.

 

It Gave That Code On Sat And Has Been Fine

 

Tilley, I know the ports on a 3.5 manifold wouldnt match to a 3.0. But if you used the 3.5 top end you would just end up with a total swap........ (brain fart).... My question was what is stoping us(as in you) from using the 3.5 topend. As I understand the only real thing would be the VCT(?)? If there were some way to bypass this and run them at a set timing it would allow the 3.5 to be swaped as a whole. (besides the TB)

cant wait to see your ETs

 

RPM Activated switches are used to put MEVI manifolds on USDM engines, should we not be able to use those same f*ckers for controlling the VCT? And use the 3.0 ECU for all the other sensors? Okay, we would still have to do some rewireing stuff, but it would be less hassle then converting to the VQ35 ECU I guess...

Sorry if I said something stuppid, electronics aren't my specialty

 

RPM is only one of many sensor inputs used to control the new (and old) Nissan VTC assemblies

 

Or is it a lot more complicated than that? I honestly haven't taken a real close look at the VQ35...

EDIT: Nevermind...

 

I figured out a way to bypass it but I will post when I know it works

 

Killer, can't wait to hear your result. If it did work out, TADA a full 3.5 motor swap would be as common as honda swaps

 

I hope so =)

 

Let's pray

 

You can build a VQ35 without the VTC if you want. It isn't hard to do. The only difficult task would be to control the VTC without the appropriate ECU because it isn't something that can just be switched on or off.

 

My buddy is coming over tomorrow so we can take his new GTO out for a spin. Should be nice to get on all those ponies .

 

Tilley,

When it's all done, try to make it down to Maxus 2005 to show it off. I'd like to see everything at the next NE Meet if Ange throws one.

 

So I take from what everyone is saying....this project didnt' work. Or if it did can someone re-share what the prognosis was on that dyno?! I don't have the patience to sift through 5 pages of random talk :P

 

It's worked fine. Dyno and track results coming shortly.

~THT

 

saturday is track day

 

Best of luck

 

I definitely am exited to see results of this post.....and, MaxSpeedSE, are you boosted or running NOS because those 60' times are seriously bada$$! NIce to see drivers that know how to drive! (hopefully this is the case)

 

Thanks Linkage for the props I have the NX wet kit.

 

14.06@99.08 is the best run on street tires (crappy kumhos)

 

that time is n/a with or without NOS? and what mods you have (lost rack of this thread) besides 3.5 bottom

 

All motor no nos
too many mods to list

 

That's a nice run there Rob. Did you break into the 100mph club in any of the other runs?

 

Whats the 60 ft on that run?

 

timeslip please.
