LOL i have seen tony's thread for the first time. this is disapointing. We were both talking to eachother off the record. I am not impressed that he posted this. there is more to the story

Man all this "off the record" talk is what turns the whole thing into a bunch of BS lol

When you start a thread to update, people expect updates.. Don't just go MIA for a week then come back claiming LTHs were a fail with the SC when there's "more to it"

I only have the 6 PSI pully on right now. I still have one more pully to go.

Oh ok, thats good to hear.

As I said, I'm trying to look for a local dynojet to see how much I will put down on that. If I do, I'll post so we can compare something a *little* more concrete.

RCZ

Now now Sam, don't with Shumby on my thread, go do it on his

I'm staying out of this one.

shumby

no there is no more to the LTH fail with GTM SC. that is fact. Fact also is the GTM's TP's also fail with the SC. There is bad blood here and I wll not get in the middle of it. I did not go missingfor a week i was driving back home and took one day off. so don't even go there. all issues I had with my car are posted and can be talked about. I will hide nothing that i know about personally. It is just too bad that the shops down there in cali cannot get along a bit better and help each other out. It would make things better for all of us.

Sorry RCZ had to reply.



On a side note you going to the track anytime soon. I want to do a fw 1/4 mile runs to see what I can do. I don't expect much as I have never done a drag race before on a real track

I haven't been dragging too much either, but I do plan on hopefully doing it sometime. Closest one is an hour away though (i Think), so its kinda a bitch to get over there.

We'll see. Maybe "soon to be a gtr's worst nightmare" can fly down and drag the car for me.

G37Sam

Sorry for whoring up your thread RCZ

Said like a wise man Shumby.. I'll leave it here

When the S/C time comes I might have to take you up on your offer, I'll prob save more taking it to jnaut. Plus he has experence now since he's already installed yours vs. some Nissan guy that honestly cares 0% about my car. When you say "normal kit", are you talking about the carb kit or race kit?

RCZ

The carb kit. The tuner kit you would have to tune yourself because it comes without fuel and without tuning. You will save money.

NewYorkJon34

I know you have a full stillen set-up & you made 390whp (mustang), Im curious to see how much more power I'd make with my full Fast Intentions set-up. I thought you would have actually made more power on the mustang dyno since stillen claims 515hp for the carb kit. And yes I know different dynos read differently, but a drivetrain loss of 125hp seems kinda high to me. I thought it would have at least made at least 420Whp-ish on a mustang dyno.

RCZ

You assume you will make more power because you have FI pipes, I'm not really sure why. Not really sure where you saw that they make more power than the Stillen setup? All the guys I've seen with the crazy numbers like 320-330whp on mustang dynos on bolt-ons are running Stillen cats and exhaust.

You have to remember a couple of factors when you look at my numbers. 1) Mustang dynos read lower than your average dyno like the dynojet Stillen and GTM use. So to say that 125hp is all drivetrain loss is unfair. Part of it is drivetrain loss, I'd say about 12% is drivetrain loss. So right off the bat take off about ~45hp from your 515 advertised.

2) As I mentioned Mustangs read lower than dynojets by a good 7-10% (take my baseline as proof. I dynoed in at 256whp on the mustang dyno, when the average baseline for a dynojet is 275whp) So you can substract another ~35hp.

3) The tune is not maxed out. We had to leave some margin of safety considering the ambient temperature and humidity down here in FL. It was 90 degrees here last night around 2AM. (I know you know) I track the car now and then so I can't afford to sacrifice safety over performance.

4) It was about 100 degrees ambient temp when I got tuned. (not much can be done about that)

Now in reality all these numbers are just numbers. They don't really mean anything. What you have to look at is the following... Stillen started at 276 and ended at 438. Thats a 58% increase in power. I started at 256 and ended at 383, that's a 50% gain. Once you factor in ambient temps, humidity, safety margin and the fact that we only really did 3 runs to get final numbers then I think its perfectly understandable to lose 5-10% in power. If I had been gunning for dyno queen numbers I would've done low temp runs with a bunch of ice in the reservoir. That wasn't the goal though.

One thing I noticed today when I went out to get some video is that oil temp really is a killer on these cars. I'm by no means overheating, but even at 220 degrees the car probably loses a good 30whp. I think I might invest a little money on heat shielding, a fan for the oil cooler and maybe even a cryo2 setup.

Q8y_drifter

I can definitely relate to the whole ambient temp issue especially during tuning. My car is N/A and my Uprev tuner had to put quite a large safety margin when tuning the ignition timing on my car because it was 130+F ambient temps and did not want any detonation to happen. He said that if I came back next winter I can gain another 10whp just by advancing the ignition timing (I made 20whp from his tune). Florida's humid summers make it even worse.

RCZ

Anyone with racing experience or a racing background want to give me some ideas to manage engine bay heat?

I'm looking at gold foil, but I want to see what other tips folks can give me. Any ideas will be appreciated.
