FF Tune, Headers, Roush Intake Dyno Results!!

[GTBOB]

Visited Finish Line Performance LLC in Milford, OH today to get an idea of where I'm at with the typical bolt-on mods. My next mods will be an oil separator of some sort and the GT350 intake manifold when they start shipping again. I'm not boasting or making excuses of the results. I just don't see many results posted with the Roush intake so here is mine. Data logs looked good through my NGAUGE. Logged -5.00 to -3.00 on the KNOCKR for the Lund FF tune. Nice and safe.



Completely stock, my car made 372HP last August (not on this dyno unfortunately). That is approx. 437 at the crank using the 372/.85 equation for 15% driveline loss.

• LT Headers (no cats)
• Roush CAI
• LUND FF tune running E85
• Stock resonator, pipes and mufflers
• Garbage Evenflow 160 T*stat (changing soon)

421HP with 379tq. If I use the same equation as above, I'm at 495 crank hp. Notice the dive at 6500RPM. That GT350 manifold will do wonders with that!

How loud is it with stock exhaust and resonators with headers?

 

[Choking_Victim]

This on e85?or what octane?

Nice growl from 2,500rpm and up. No rasp or crackling at all. Sounds great at WOT. You can tell it's "not stock" but still can creep around and sneak up on opponents.

Here is a short video of it in my garage:

E85. I fixed my post, I forgot to mention that :doh:

So I can expect to be somewhere around here, how awesome. With that GT350 intake manny it would be n/a nirvana.

Nice numbers.

Looks great!

Mine made 425rwhp 391rwtq on 91 octane with a custom tune. I got the flex fuel tune for free over christmas also and haven't tried the tune yet because I'm no where near any E85. I wonder if the FF tune will be better than my custom tune on 91 and be close or be over 500bhp....

What exactly does NEGATIVE KNOCK mean in the Ngauge?? I notice that as well when running e85. Is that the amount of added timing the ecu is adding over the base timing map?

Correct that is the car adding timing...a positive value indicates timing being retarded.

So on let's say pump 93... I would assume you should be swing any negative knock? Only on E85?

The car will advance or retard based on fuel quality. The lower quality or octane the fuel the less advance etc.

Nice tq numbers The dyno operator said that the friction of my drag radials on the rollers would give a lower reading vs the stock tires mounted up. My quarter panels were covered with rubber after those 3 runs. All subsequent sessions will now be on stock tires lol!

But like I said in my original post, I won't make excuses and I'm using the graph as a learning tool for my next round of mods. As soon as the GT350 intake manifold can be shipped safely, I will get one. Can't stand that dive in power at 6.5k rpms.
