Hi gents!



Took the old 302 to the dyno today since installing my most recent cam from Ed Curtis @ FTI.



Just a little background on my previous setup - a previous cam from Ed (from an old combo with AFR 165 heads and a Cobra intake) with Trick Flow 190 11Rs, Holley SM2, 1-3/4 used MAC longtubes, summit universal 3" X-pipe. 4.10 gears, 80mm MAF and home-made 4 inch MAF. Even with the old mismatched cam, it put down 350/341 and ran 11.8 @ 116. Let me say from the get go, I made it clear that this car is driven a lot. It's no 500 mile/year show car or race car. It's made several trips across the midwest (I am near St. Louis) to Louisville, KY Des Moines, IA, it goes everywhere.



Told Ed what I wanted - a cam to take advantage of the induction and exhaust system I am using, with a broad powerband, and I let him know I am not afraid to rev my stock bottom end to 6700ish, give or take.



Below is the dyno sheet, I'm working on uploading the dyno video.





Don't mind the smoke in the video, just my 137k mile rear main seal that likes to make itself known when high RPMs are in order, spitting a little oil on my exhaust.

Only difference between the setup I mentioned above (before cam) and new is a new electric water pump, and of course the cam. The powerband is broad and fun, I am already making 300 ft-lbs of torque before 3k RPM, and this dyno run was only done once because you could hear in person (and sort of see the mini-dip it takes in the graph right before 6430 which is where peak power is) that I am likely experiencing valve float - I am on the stock springs that came with the head, out of the box, and the air/fuel log on my dyno run shows the 2 banks differing quite a bit and jumping all over the graph after 6400 rpms.



The heads are straight from the box 190 11Rs with 56cc chambers with no porting, and the lower intake of the SM2 essentially has light porting to help match the heads, and cleaned up casting flash in the upper. Also, when I say stock bottom end - I mean the oil pan has never even been off of the motor.



This car was bought as a bone stock 86 GT, and I installed all parts myself. There is no weight intentionally taken out of the car (stuff like aluminum heads/radiator lost some, as well as smog removal), and it has power steering, A/C, power windows and locks - in other words, it is the definition of a street car and the manners reflect this as well. It's a 1.5 hour drive to and from the tuner, and it purred like a kitten smoothly at 2,000 rpms on the interstate to (yes, even untuned) and from the appointment. I repeatedly beat the piss out of it on the way home when I had stretches of open road, and it just begs for more!



Can't wait to install a set of springs and go hunting for some 120mph trap speeds.

The best part of your entire post is you did all the work yourself. I have a lot of nice expensive parts in my motor build and I'm sure if I had an experienced builder put it all together it would probably have a few more ponies, a little more torque and run a little bit better but there is no beating the feeling I have when I'm driving around in something I did myself. Sounds like you get that same feeling:king:

Thanks a lot, Brian! The reason I do it myself is a mixture of reasons. Between having nobody to blame but myself if things go wrong, and the satisfaction of knowing you accomplished something, it's definitely fun. I've also seen first hand where "shops" take their sweet ass time and show little attention to detail because they view it as nothing more than a road to payment. When I put it together, I took twice as long and checked things 3 and 4 times. This was my first cam degreeing experience and I spent 2 hours alone verifying valve events and timing the thing.

Nice

I taught the 11r heads came with springs that are something like 150 on seat and like 420+ open (can't remember exact numbers of the top of my head). You don't think that instead of springs that it could be your lifters causing valve float?
Great numbers by the way!!

Thanks! The lifters were brand new from Ford Motorsport, less than 5k miles on them, and guys have taken them higher than I am. Pre-load is half turn past 0 lash as well, which I think is definitely fine for 66-6700 rpm.

Wow. Makes me wonder what would happen with a custom cam in my 331 which has AFR 185's and TF R-series (not the box) intake. After I complete my exhaust upgrade a cam will be on my list.

Contrats on the stellar results.

Thanks, man. Port the Trick Flow intake. David Claflin has some posts on here showing what the inside of the R looks like. Inside, the runners taper down to a smaller cross section than either end of the runner, during the 180 degree turn, and you can't see it unless you cut it. Have it ported by someone capable. Stock block? I told Ed I wanted no more than 6700 RPM. Call me ballsy but my local tuner who is very reputable, hasn't broken a 302 stock block on the dyno around 7k RPMs. I'm ready for people to call BS, this is just my second hand relaying of his experience. I have a Romac balancer and when the transmission dies, I'll get an aluminum flywheel as well.

Ed was great to work with and he's the best in the business if you ask me.

Dyno numbers be damned, this thing is fun on the street, just as it is on a long stretch of open road. 300 foot pounds before 3k rpm kind of dispels the whole "big heads kill low end torque" myth. The cam ties it all together and I'm probably gonna leave it as is and just drive the piss out of it for a while!

My 331 makes 348hp & 352 ft-lbs. 300+ ft-lbs from 3000-5800. Kinda in the ball park you are in except you have 20-some less cubic inches.

As I said "kinda in the ball park". Head to head we would, probably, be a drivers race. His result is impressive.

Whats the best your car has ran? OP said he went 11.80 at 116 with his old setup making 350/341.

A.) Haven't run it yet. Just got it and I am correcting a few things before I start running it. So I don't know yet and any guesses would be pure speculation.
B.) Even when I do run it, it will be on regular radials at least for this year and maybe next year.
C.) Once I do run it, I will find out how much driver mod I need to do.

So it won't be apples to apples anyway.

But put two equally capable driver's in the cars and I am pretty sure it would be relatively close. 24 whp is notable, but not overly significant.

As I have eluded to. Props to the OP. His results are impressive. My hats off to him especially since he has eclipsed me on the dyno with less displacement. I am using his experience to ballpark my expectations once I start running my car.

Thanks guys.

Hoping for 120mph traps and 11.4s this year. I don't expect my HP gain alone to get me 4 tenths faster, but the usable RPM range I have now blows the old one out of the water.

Whats the total Combo for putting out 372Rwhp?

TFS 11R 190CC?
Custom Cam FTI?
Holley Systemax 2 intake

What yours whole exhaust system for pulling 372rwhp?

What size injectors? What size maf? What size TB?
