Then I read that he's offering ceramic coating, hence my confusion.

I emailed Tony last night, and his response to me was "The temps will be lower but the coating cannot hurt it will only help. The coating just keeps more of the heat in the tubing which is ideal for a force inducted application EPECIALLY turbochargers since they build power off of heat."

At this point, I'm under the impression that if you're planning to stay NA (as I am), it's really not necessary and an unneeded extra expense. But I'm waiting for Tony to confirm on that.

I sure hope that isn't a quote from Tony since I'm under the impression that LTH can't be used with turbo applications. I'm assuming he meant Supercharger but we all know the saying about assuming.

Where are they at?

Hell don't get me lying, I could go back through the Modifieds that I have but that would take FOREVER haha. Maybe I'll look through a couple but I seem to remember something about Scotsdale being one of the locations.

Yeah, Scottsdale's just as far as Chandler lol.

No, he said turbo. I remember that clearly. BUT, I think at that point he was talking in general terms about the benefits of keeping as much heat in the headers as possible for turbo apps. Like he wasn't specifically talking about his LTHs being used in conjunction with turbos. He was just talking about why you'd want to ceramic coat headers in general if you have a turbo.

I understand the reason behind a dyno and what it does for you, what I'm asking is why do they pick 1 particular gear (obviously now for the 1:1 ratio thanks semtex!

) But I mean, does that give you the best Total output?

I'm just wondering for 'Practical' output... Say just like you would on a 1/4 mile, do a dyno thats actually going up through the gears just like you would in a race... Or would that be just completely retarded?

If you went up through the gears I think you'd just end up with a separate chart for each gear. Because think about a dyno chart. On the x-axis it has the rpm scale. So you go through 1st gear and there's one graph showing your hp from 2k - 7500 rpm. You shift into 2nd and there's another graph showing hp from 2k - 7500 rpm. And so on and so on. On a 6MT, you'd end up with 6 dyno sheets. 7 for those with the 7AT. As for why they choose the gear with 1:1, I don't think it's so much that it gives you the best numbers, but more that it gives you the most accurate numbers, seeing how engine and transmission speed are in synch with one another.

Actually, giving it a little more thought, if you ran through the gears, it look more like 1st gear: 2k - 7500rpm, 2nd gear: 4500 - 7500 rpm, and so on. Because it's not like your rpm is going to drop all the way down to 2k when you shift from one gear to the next at redline. Heck, depending on how quickly you shifted, it might only drop to, say, 5500 rpm.

So it doesnt just measure the HP/TQ curve as a whole, it just measures a specific gear? I used to think when you saw little dips evenly placed through a dyno, that was a 'gear shift' drop... I didn't know it was only in 1 gear...

semtex · 04-08-2010, 01:36 PM

Yeah the measurement is just in a single gear. You've seen my dyno vids, right? If you watch closely, you can see them run up through to 5th gear quickly, then they just hold it there for a sec at like 2500 rpm while they hit the start button on the measurement software, then they floor it all the way to redline and then they're done.

I wish there were more shops over here on the west side.

Runs were done in Tempe at (S)uperior (R)acing (D)evelopment with Xact Dyno (first listing on UpRev's Web site for Dealers/Tuners) which is in the same shop (separate business run by Tim).
Yes - know about Intense Motorsports' rep.

The guys at SRD are good and not too pricey. Chet the owner is real straight up guy. SRD are also going to start distributing Tony's exhaust (and LTH's no doubt). They sold one to another customer after they saw the quality and heard mine.
As far as what I'm going for with this car - keeping the wife happy

since it's her daily ride. If it was mine I would be going all out (TT kit, hardened tranny, etc) and going to SpeedWorld and Firebird to challenge my old Turbo Regal buddies.

I guess I just need to go to a dyno shop and have them see what my baselines are... And let them explain it to me as they do...

How much +/- will a run set you back? Say if I wanna do 3 for a good average to use as my baseline?

semtex · 04-08-2010, 01:41 PM

This one will give you an idea of what I'm talking about re. shifting up to 5th, holding it for a sec and then gunning it.

vipor · 04-08-2010, 01:41 PM

Definitely all one gear. I think I smell smoke... Coming from your ears Cwis?

I didn't understand the whole 1:1 ratio thing before though heh.

Dude let me know when and I'll come out with ya! (So long as it's on the weekend since I'd never be able to make it there on a weekday lol)

I need to get a baseline strip number as well...

Depends on the shop. Anywhere from $70-$100 is the norm. And 3 pulls is also standard.
