Congrats!

 

You next


Ricky try and get a vid behind the car next time?
Lets hear that thing.

 

Very nice! that's a butt-load of torque!

 

after you

BTW 480 miles on it, so I'm calling for an appointment tomorrow

 

Bob,

Besides the cam surge at idle and just above the car cruises very well, and to tell you the truth we didnt get alot of time to tune that when Jim was here.....

The motor is butter smooth. Jim uses Strasburg Racing to do all of his machining and they have a Top Fuel so enough said about that (http://strasburgracing.com/index.html).

When you get out of the cam surge and are crusing or at WOT, the engine is literally as smooth as a stock motor.

The car runs very well thru the gears. Jim and I were quite suprised how well it pulled with the 3.07's, but I guess the rwtq that it makes explains it. Bob, I am looking forward to feeling the ZF with the 3.45's. I know going from 3.07's to a 3.45's is a huge jump, but I am certain it will be noticed.

So far the car's coolant hasnt been over 220, but I really have not been stuck in heavy traffic yet, but in saying that if things workout I will put a Dewitt's or Ron Davis rad in it for my peace of mind especially if I get crazy and bring it to Mosport.

There you have it. Take care Bob, and I hope the family is well!

 

Congrats! Now go beat on that thing!

Wait, where is the graph...


Enjoy it man. Sometimes there is a lot to be gained in leaving well enough alone and enjoying driving it...

 

Very cool, I'll be its a blast to drive!

 

Rick

I would be very interested to know the AF, unless they have this working next time, I wouldn't go back to the same dyno. There could be some HP & TQ waiting to be extracted by the tune right there!

My new XFI 2.0 came with a wide band O2 , does your Classic use a WB O2.

EDIT,,, BTW, IMO,,, you keep the heads and cam and switch to a HSR, and gain another 10-15 RWTQ with no other mods, and with a potentially improved tune, you could be close to 490+ RWTQ . My next big cube engine will be all about TQ for sure.

 

Nice numbers!

 

Nice numbers Rick. Congrats!

Jim always builds stout engines.

 

Yes I do have a WB for the FAST. I should have data logged it but this was $40 for 2 pulls and I was banking on the WB working properly. Therefore the dyno operator wanted to get the cars on and off the dyno without changes and being it was only $40, I was good with that.

Jim and I spoke last night, and I think when I go back I will bump the timing back up to 29 (its at 27 now). I find my CR is on the edge of pump gas so I put in a bottle of Lucas octane booster in the tank before the dyno with some 94 Octane. I think I will continue to do this as well since I will probably only put 1000-2000 k's on the car a year "if that".

You might be right about the HSR, but I need to revisit the dyno with the header leak fixed and possibly the extra 2 degrees of timing "could" yield me some more power....I still think the MR is the ticket, but I have noticed that you have made great power with the HSR that you modified for the stock hood.

I will stick with the MR as the combo isn't maximized in my opinion at this time. However in saying that, I am pleased that the short runner intake yielded some pretty good rwtq, but is obviously that the small heads are holding me back in the rwhp.

As a thought. I spoke to ***** the other night, and he advised that the ARH headers he bought picked him up 1.5 mph at the track which is probably 15-20 rwhp considering what power his 406 is making. I have a "feeling" the exhaust changes will gain me 20-25 rwhp more on top of the 434rwhp.

I will venture on with my FAST, and exhaust and see what more gains can be had if any. At any rate the car is very quick, and had no issues with Ford's big dog the "GT500" which was nice.....

After I revisit the dyno, I will post my findings.

Anyone know what drivetrain loss one can expect with the 4+3? I heard around 17%.


Take care!

 

Sounds like a plan, I am hoping my new tune will yeild more than the 428-458 that I already have, and that was with two muffler holes plugged

Take my advise, or not, and drive it and enjoy the car for a while before you rip it apart again,,, my saga lasted 3-4 years of me tweaking and dinking around,

all my neighbors would ask me,, "why is your car not on the ramps? it always has been for as long as we can remember?"

 

"and possibly the extra 2 degrees of timing "could" yield me some more power"

Could be. When my motor was on the engine dyno we started out at 32 degrees of timing. Tuned in the AFR and then we were going to make some real good power and advance the timing to 34 degrees. The engine promptly lost 20 horsepower. We dropped it to 30 degrees to see what would happen and regained all the lost power. We left it at 30 degrees and it is what is on the car now.

The exhaust is all important for a number of reasons with maybe the most important being the "tug" on the intake track during the overlap period to get the intake cycle off to a good start. So you may very well be right on the potential horsepower gain.

Talking with Tony Mamo the AFR 195 Comp heads were designed to be in the 550hp range. He had one motor with maybe 565hp(memory). He thought if all the stars were lined up and everything was perfect one might be able to get 600hp out of a set. You would have to be using every available cfm in the head.

 

Time will tell. I am going to be moving the timing up to 29 in the next few days and taking it for a rip. I will see if I have any pre-detonation, and if I dont with the higher octane that I believe I am making more power....

At least a thanks is in order for doing your R&D.

I would be pleased with 550 chp. I don't believe 434 rwhp with the 4+3 is quite there, but then again that dyno did seem to be a tad on the low side, but who really knows....

But in saying that 470rwtq is certainly at the 550 tq level if not more which makes it exciting to drive.

Take care!

 

Wow, that's a boatload of power. Good job and I can see it lasting for a while. I've followed the build and there's nothing quite like doing it right. That's Marine Corps power right there and I don't care who ya' are.

 

"At least a thanks is in order for doing your R&D."

A big thank you. By the way the check is in the mail.

 

those are great numbers but don't get so hung up on them that it prevents you from enjoying the ride!

congrats!!

 

great numbers any way you look at it,and to dust a gt500 ain't to bad at all.

 

Rick, as you move forward into the world of tuning, it's important to realize that max power @ WOT is where you want to be; but if you're driving a street car you need to play with your midrange cells as well. That's what gives you that tip in rush and allows you to make use of your part throttle torque.

Enjoy it brotha, you're gonna love the onramps........

 

Your only 28 HP under my 381 CID On E85.
