I rather have a turboed VQ30DE then a VQ35DE I guess... :/

 

just so you know i put this in my womans 97 daily driver the turbo motor is going in my 99

 

do u think this set up coudl handle a supercharger, considering that i probalby wouldn't have the jwt cams and turbo heads....?

 

With such high compression you would kill the engine when running boost I think... To much pressure then. How is it holding up right now? How many 11.5:1 CR miles?

 

up too 400 miles and a/f is still good and running great

 

Damn dude, running good there! Keep me updated!

 

any numbers yet?

 

I believe he said he's gonna dyno it tomorrow!

 

aand i am saying that a vq35 in a 4th gen is going to be faster. and he didnt push it a little farther. i want to see pics and numbers and when i get my project done i am heading to the track and a dyno to see what i am running.

 

Sweet can't wait to see the numbers. I say 230 whp.

 

I'm saying 210whp.

 

Cams, higher compression and stroked, with the headers should make like 70-80 whp.

 

My prediction is 218whp. I bet it could get up to 235-240ish with an MEVI and JWT ECU.

 

i do not really uderstand where that cr comes from

 

holy sh*t, 6 speed tranny can bolt up to the 3.5 block ehh? any extra wiring involved taht would complicate things? I wish i knew about this before my tranny died, i would have sold the SC, and go wit 6 speed tranny w/ this setup....cant wait till tonight! dyno dyno!

 

this should be nice i'm going to guess about 225whp. can't wait to see the numbers.

 

crazy... post us up with any new info

 

umm doesn't the VQ35 come with a 6-pseed on the max?

 

well the dyno sucked cause i ran on a dynojet prior to this for baseline #s then yesterday I ran on the mustang awd dyno which is completelty different cause my buddys z dynoed around 35hp less than on the dynojet the max did like 179hp and 181tq but the good thing is it had torque from start to finish and it was nice and smooth. BTW I got home to find my stock cat is all but clogged so I replaced it with a resonator I had layin around for mine and that made a good difference. Then I hung with a 350z with a injen, from a stop he would get me by like 2 cars but once i was moving he couldnt pull away

 

awesome man. got a graph to compare ?

 

I think the only reason why a mustang dyno would read **that** low is because the weight of the car was no put in correctly.

 

I have to scan it so it may be a day or two

 

what did the z dyno stock z's dyno like 220-225 sometimes 230.

 

How could u tell your cat was cloged? what does it feel like?

well lets see the next dyno. i still say it wont make more power than a stock vq35. but props to you for attempting something like this. and a stock vq35 6 speed can hang with a 350z. i know that cause i did it.

 

I have seen a clogged cat vefore on another car that ***** glows.

 

Take that baby to the track

 

Doesn't vsamaylov sound like a whiny little girl?

 

 

the max goes to the track for idrc at maple grove on the 25th..... i need more power, but i have no more money.....

 

well when you look through the cat and it has chunks stuck in it then you know its bad

 

do you mean in a stock 5.5th gen or when the vq35 is in a 4th gen?

 

i bet i could hang with a stock 350z as well. probably even more so when I get a new clutch.

 

it all depends on who is driving. If it was my friend who sees 13's all day in his stock 350z then no.....but if it's the other 80% running mid-low 14's then we would both be right there.

 

last night I made some changes in plugs and that seemed to helpand also I had 2 people in the car rather than 4 and the 350 was dead even other than the car length i lost due to tire spin where he hooked up, the guy is a good driver he chirped 4th when I was running him.

 

Well 180 whp on a mustang dyno is right around 208 or so hp on a dynojet so i'd say it's right where most people thought it would be and is running strong.

 

I'm talking about that 80% right there. lol

 

Me too. I have yet to see a 350Z in the 13s at my track other that the ATI Procharger Project 350Z. I'm usually right with ET/MPH of the 350Zs, give or take .1 and 1mph.

As for this 3.5VQ swap and the 179whp/181wtq on the Mustang dyno. This car would probably see around 197-201whp and 199-204wtq on a Dynojet, maybe. Typically, a Mustang dyno sees approximately 7-10% less power than a Dynojet. Other things to keep in mind is that the Mustange dyno typically shows a longer and more smooth power curve than that of the Dynojet.

As for the cat converter, I'm curious as to what these "chunks" are. A substrate cat converter (OEM), has a densely webbed brick. You should be able to see hazy light thru the converter. If you can see any sort of light, the cat is fine. Now, if the cat is bad, it should be quite obvious because the webbing will be melted hence the reason cats tend to glow when they fail. It is quite possible that since he is running such a high compression, the exhaust gases and possibly a lean condition could cause the cat to melt and fail. If this car made the power it did on the dyno with a smooth power curve, then the cat is not clogged. A failing cat will cause a major power loss and the furthest O2 sensor will usually fail due to the extreme heat (ie CEL).

 

Are the heads in a DET version different than in a NA VQ???

 

ok when you look through the cat it has portions that you cant see light through I know what a good cat is i do have a performance shop im not your typical moron. it goes to the dynojet either next week or the following at idrc in maple grove raceway. compared to a 3.0 the torque is sick and is very high even at low rpm nothing like the 3.0
