A little back ground:

here's the graph on the mustang dyno the first time Glen tuned my car, comparing the unknown tune VS Glen's tune, car still has PRC 2.5 LS6 heads, LS6 intake, stock MAF with ported end,lid,no cutout



Final number is: 399/378
Added Fast, Final number: 413/365 with cutout open, graph is on the next sheet

Here's the last number after TFS 215 installed and re-tune. This is swapping PRC 2.5 LS6 heads to TFS 215, all other variables stay the same

Updated Dyno Run 10/10/2012


so: 24 rwhp and 38rwtq gained from swapping PRC LS6 to TFS 215.

i'm really stoked, not because of the peak gain but more because of the overall bump throughout the power band. now i can literally race stock G35s on half throttle....tried that earlier today, but that's another story

i'm done with the quest for power for now. rear end is going to be next on my list.

here's the vid of the dyno run, there's some coolant spurting from the back of the engine bay on the last run, doesn't happen when the car on idle after that...really weird. you can see it on the video, i'm thinking it may be coming from the coolant block off at the back of the driver's side head. but i won't know until i take off the intake manifold to find out.

the car has:

TFS 215 milled to 61cc
232/234 .595/.598 112
FTP 98mm lid - 85mm MAF- FAST 92/102 intake manifold
LQ9 Block
Hooker 1 7/8 LT, DMH E-cutout, Borla exhaust

What heads are on the motor?

Ported 243 heads from TSP.

I want to get more torque out of the car

techls1

Are those the 2.5 LS-6 Heads? I have a 346 with the 2.5 5.3 heads with a V3 and made 405 TQ.

Yes it's the 2.5 ls6 heads, what's the V3 specs? I'm thinking its my LT that killing the torque, it used to make 408 torque

V3 specs are 231/234 111 LSA. From what Texas Speed has said in posts on here, the V3 is going to be better in regards to under the curve TQ numbers and will carry out farther, netting more HP. Only downside is the high lift the V3 has.

Pardon my noob question but I'm new to this whole cam thing, why would the highlift be the downside? Harder on springs?

^ Yup.

The high lift is harder on the springs. Not by much though. Lobe style has a lot to do with it as well. My cam has a little higher lift than the Torquer v3. But it nets me a bit more torque. I personally like having high lift on my bigger cams. Makes for a more fun street car. And by hardly putting miles on my car im not too worried about it. The vendor i use for most of my stuff told me to check my Patriot 650 springs every 12.5k miles.

Is there anyway to get around it say by buying stronger spring? I'm really interested in swapping to v3, I'm still thinking my setup should net more torque being its a 6 liter, but it is what it is.

Honestly, you should check your valvesprings no matter what your running at some point. Alot of people are going 70k miles plus on 650 lift springs and a 650 lift cam. My cam is slightly over 650 lift. and after talking to a few vendors on here the advice was to stay with the 650 lift springs. I love TSP Cams but there are Custom grinds that can net you good torque curve as well. but a lot of people love the TQRv3

Yeah I might do that, my next plan originally was nitrous or fast intake, but maybe I'd be better off with getting another set of springs and cam and squeeze more out of this setup, I still have ls6 intake and stock ported tb fwiw.

Is this A4 or M6?

iTrader: (11)

M6 sir.

dang man, if you are going change everything on the car,you could have bought a stock one and done what you wanted to it.

Swapping from the v2 to a v3 is not likely to get you enough gain to justify the expense and work.

I would focus on other things.

best advice posted in this thread!

JP:all I did was just exhaust because they're rusty and one of the cats actually leaking and replaced the ls7 clutch, swap the tb that was in the car with my S2 ported TB and now the fast coming in. I love this cam selection too just want to squeeze more torque out of this setup

Thunderstruck: I agree, fast 102 coming in to the car tomorrow.

And if I bought a stock car I wouldn't get the suspension mods and a 6 liter block.
