As far as TT superior for tracking the car. Here in FL, we have a member that has turned his Z into a race car and is using the Power Enterprises TT kit. He has had to do so much custom work just to keep the car cool enough to run on the track with the TT's under the hood. A few examples: Retardedly huge radiator, removed AC, custom front bumber, custom ducting, custom vents in hood, just to get it near normal operating temperatures. You cant just expect to slap a TT kit on your car and blast down the track like you could N/A.

 

hehe yeah, but at least I hear about everyone and their mom's TT or ST Z that "gets run HARD at the track with 0 issues, a very linear and controllable power delivery, and has been running GREAT since day 1, no problems. Never overheats, etc"

and if someone blew their engine or car overheats, well then everyone will pinpoint the problem, tell the guy he "just needs to spend a crapload more money than he thought he'd have to, to get it all fixed up. THEN it'll run perfect"

...right?

FI is supposed to be the "cheap" way to make big power from what everyone says on these boards. Funny how it never ends up being cheap.

 

My mechanic noticed this as well and bought the newer one for his race 350z but upon inspection they are identical. No improvements.

 

TT's are great for "roll-racing" and impressing the 16 yr-olds at the local "spot", but from the research and examples ive seen in person, nothing beats an SC for reliable "bolt-on and go" FI.

 

Booger: thanks for trying to keep thread on track.

mchapman: thanks for confirming no difference in pumps.

 

yeah, I agree 100%. That's why I'm pro-supercharger as far as the Z goes. I was being a little sarcastic when I wrote that, but might now have been noticable

 

Bill - It NEVER fails that any discussion around a built motor ends with "why didn't U go with a ST or TT".

BTW - I'll be bringing my G over to John next week & let him start on my Vortech ( finally!! ). Don't know if ya saw my post last week about cams but JWT recommends their S1 cams for ST/TT & their S2 cams for SC ( different durations & overlap, I recall ). I also picked up Charles' ( Phunk ) OEM heads off the Classifieds & am gonna let John's flowbench guru do some minor porting & bowl cleanup. I'd LOVE to swap the valves for some Ferreas but those R mega-expensive & I think the money would be better spent on the S2's + headwork. Of course, if I did the oversized Ferreas then I'd need to run a ST or TT, right???

 

I never participate in putting the s/c guys when they build their motors, but it make absolutely no sense to build a motor and then go with a s/c, unless it was a forced build like booger for example. If you are spending the money to build the motor you obviously are wanting more power then the stock motor can handle, why limit your self with the s/c output? Also look at all the work you are putting into your motor....Why spend all that money to not use the motor to its full potential? Not flaming just wondering. The work you are describing is not cheap.

 

I suspect you will see some good numbers out of the T-trim once I get a bigger IC and upgrade the IC pipes and replace the SS box with the Utec , or if any thing better comes out by spring

 

Bill - I THINK John's just gonna stick with either the SS box or try the Uni-Chip. I offered to upgrade to a standalone but he's not real high on anything out there right now.

GMan - I guess, like Bill, I'm just tired of everyone trying to shove a turbo into my engine bay w/o knowing all the facts. I've had this Vortech for almost a year & got it for a GREAT price from Brett ( tig488 - thanks again, my friend! who sold it & replaced it on his G35 with a TN S/T ( shameless plug here!! ). I'd already upgraded it to the T-trim & larger FMIC plus had it polished &, quite frankly, would lose too much $$ should I sell it now & buy a turbo kit ( which are more expensive in the first place ). Do I agree with U about the available turbo kits developing more power than any of the S/C's out there for our cars - yes. Given the choice to do it again would I go T/T - again, yes. But given my current cash outlay & also the traction issues that seem to come up, I prefer to just max out the Vortech & make up the low end power difference w/nitrous.
Also - I haven't made the final decision to change cams or even build the motor so all this may be a moot point. I only have 15k on my VQ so unless I come across some serious OT before Thanksgiving, I plan on bolting the Vortech onto the stock internal'ed motor & see what happens. Wish me luck!!

 

OK, I see your point. Again I was not flaming. I myself had a vortech before my TT. I sold my vortech and other supporting mods losing a combined total of about $4K on parts and the labor to have the kit installed and tuned. Fortunately I was able to do this financially.

Good Luck with your setup. A t-trim and nos definately something I would like to see.

 

with the T-trim and my AT5 . I cant even think about going WOT in first gear and most of second with out lighting up the tires and hitting the rev limiter . SO I wouldnt even think about using NOS

 

good luck with the new motor kzanard.. We actually live in the same town whether you know it or not I've seen you drive by many times.. and I saw your car running real bad first hand up with Jeff last spring too..

Would love to meet up and check out your new goodies one of these days.. and to see your tune.. I just finished the final tune on my car with the blue emanage and AAM fuel system with 440cc injectors.. but I don't have a built motor like yours

Mike,

Thanks. I don't think the new internals will give me much HP, just more peace of mind. Since we have similar fuel set ups we should be in the same power area (depending on other bolt on mods). Shoot me a PM anytime and we can meet up anytime.

You obviously don't understand the concept "diminishing returns". There is a point at which any benefit gained is outweighed by the cost of getting that benefit.

Ultimately, the power TT kits bring is great if you can get it to the ground. That typically means you have to upgrade much more than just the power output of the motor.

The 350Z was not set up to be a 500+hp car. Therefore, the further you push it over that threshold, the more re-engineering you have to do to the **entire** car to allow it to perform to its potential.

 

Have you ever posted your current dyno? I'd like to see what your torque curve looks like now.

 

maybe to make sure what happened to his motor doesnt happen again? im gonna build my motor but not boost it nuts like...i just want it to be a reliable safety thing i guess..*i say im not gonna boost it more....but wait till i get it...lol*

 

I never had him print it out because we weren't finished and I had a couple things to figure out . I was at [ with 3.12 pulley ] 4.8psi at 4000rpm...6psi at 4500rpm...8psi at 5000rpm....9.7 at 5500rpm...11.8 at 6000rpm ....13.2psi at 6300rpm where the belt starts to slip . Im sure the bigger intercooler will help alot
