# 408 Dyno Tune w/video & sheet

Does anyone have a formula for what that might mean it makes at the Engine vs Rear Wheels? Added Dyno sheet finally Attached Thumbnails   Last edited by neblackshirts; 03-14-2017 at 03:00 PM.

A better way would be to have a table of driveline components (trannies, rear axles, etc.) and the drag each contributes to the whole picture.

This will increase a bit with a stouter rear, higher stalled auto, stouter auto, heavier wheels, IRS, etc. It will decrease a bit with lighter wheels, CF driveshafts, etc. So the math is, if your car is an A4, divide your HP number by .82. 470/.82= roughly 573. YMMV but this gets you a defensible number.

That's a good point and something I never thought about. So do you think that the current duration at 243/251 and 111 is a little much? If it matters the motor was built for Nitrous but not hooked up or ever been sprayed and not sure if at this time I'm interested in nitrous. I should add as of right now the car is going to be mainly a street pounder and rarely make it to a track. I need to post the tune The Shop did as I have a few questions about changes made. But as you said Tony Mamo mamomotorsports would be an excellent source for his knowledge.

Made 584 RWHP with M6 and efficient driveline FBody. For a street car DD, no nitrous I would have Kip @ Cam Motion grind me something like 239/243 114*+3* but talk with Tony he will know best.

You think even on a Mustang Dyno it still should be north of 500? The shop owner told me that his mustang dyno is pretty hard on giving great numbers. This is the same shop that's putting together Kyle from 1320video's twin turbo zo6 that he posted on his 1320video youtube channel.
I'm not sure where I'd be leaving hp on the table at, maybe the cam is overly aggressive for N/A as the motor was built for Nitrous but haven't ever spayed.

We have damn near the same cams, you have better cyl. Heads with a 2.08 intake vs 205.5, you have 25 or so more cubes so your heads work better on the 4.030 bore, you have a102 intake and TB. I rolled a 534.5, 518 corrected on a Super flow on a rainy day, you should easily be in the 500''s , you're could be.50-60 short, there are a lot of 408s in the 500s.

It's the fast toys 104mm lid but maybe others have a better intake they use. I've also been thinking about switching to either Injector Dynamic or Fuel Injector Connection. Guess I'm just trying to figure out where I could possibly be leaving power at.
 03-29-2017, 07:48 PM #17 TECH Resident iTrader: (3)     Join Date: Nov 2011 Location: Sonoma Co. Ca. Posts: 774 I'm using LS3/7 42lb. Injectors, said to be good for 550 rwhp. I'm using an LS3/7 MAF, you don't need anything more than that. You are using an A/T trans. so there is a slight power loss there vs the manual tran's. Not sure if your exhaust is hurting you, do you have cats? 2 into 1 system? Is your CAI built with tight bends? Last edited by 64post; 03-30-2017 at 09:08 AM.

Posts: 774 You have the better heads, more cubes, essentially the same cam, a little less compression, go figure. Mustang Dyno vs. Superflow?, I'm at sea level so that helps, I use one of the best tuners in N. Cal, appointments are months out. Not sure what to suggest here.

I envy you guys in more populated areas, we have basically ONE shop (The Shop Inc.) within a 60 mile radius and around 700,000 people which is crazy but he's a pretty nice guy and actually likes his job wrenching as apposed to having to do the job because he has no choice. He's actually building or should say built Kyle from 1320Videos White 01 ZO6 Twin Turbo'd.

I'm on a straight SD Tune as nobody has been able to get the TSP 100mm MAF to read right. My exhaust is a custom 2-1 into a Borla XR-1 that makes the car actually sound maybe a bit too tame but doesn't get any complaints. CAI wise it's a straight shot in the FAST 102mm but I've kinda been wrestling with the tune as my cold starts, idles, and basically low airflow situations have been a handful. Has been suggested to try a NW 102 or even the Holley Billet 105mm throttle bodies. So I might try a new throttle body and maybe either Injector Dynamics or Fuel Injector Connection injectors a shot together and see how the car responds.
