OK......I think we have success!! Check these numbers and out and let know your thoughts


Max HorsePower 119.7 @ 5100

Max Torque 143.3 @ 3100

Top Speed 120 @ 5200 RPM and still climbing...The rear end started bouncing on the dyno and the operator pulled back.

Compared to the last Dyno before the rebuild, Max HP was 94.6 @ 4200.
Their Torque sensor was busted on the first test, so I only have the HP to compare.

Start to finish was about 3,000, but the good part is that I didn't have to pay that much. Thanks to a mistake the transmission shop made I only had to spend about 500.00 of my own money on it....

Michael, congradulations on the hp output. Thats about 150 HP at the flywheel. Damm good considering you are using an adapter, vs a direct log mount.
i feel good about your camshaft selection cause its the same as mine.
Your attention to detail is magnificient.
I had 1 question, what rocker arm setup are you using? Good luck. More power to you. William
 
Hi Micheal, great to see those kind of numbers. Your build up is almost identical to mine. I too am using a carb adapter but I upgraded the rear end to an 8" with 3.25 gears. What exhaust setup do you have and what carb are you running with?

Well done.

michael, you may have more power available with a check to mike at FSPP for a set of 1.6 roller rocker arms. But it will cost you $400.00 for about 5 HP. Just goes to show you the power potential with some common sense good old hot rodding bolt ons. Again, a very sanitary vehicle from interior,exterior to engine & compartment.
I would love to see what you would turn in the 1/4 or 1/8 mile drag strip.
Keep up the good work. William
 
wsa111.....I'll keep that in mind when I start looking for more power...Thanks for the input. Michael
 
mcmillal.......I'm running a dual pacemaker header with duals all the way to the back. No X pipe...My carb is the Holley Weber Progressive 2 barrell from Stovebolt.

Do you have anymore pictures of your car, I would like to see them if you don't mind. By the way nice numbers!
Thanks,
Daniel
 
Those numbers really give me serious inspiration to get my car to the dyno this spring when the local mustang club goes.

Very nice work...you continue to impress me both inside the car and outside.

Agreed. It is a good example of a typical street performance buildup that others can measure by.
 
I find published dyno results and engine specs very useful. Seems like small minority thinks the same way, just look at how many results there are.

Mraley published this info while I was building my GEN2 engine, and of course I compared the two back then and had an idea where I was going. Anyways, I find this very interesting and more interesting it came when I got the engine dynoed.

Nowadays I'm in belief that 160-170 flywheel HP is pretty hard to exceed with US head w/log w/one carb, without very extensive work on every aspect of the buildup. Money consuming, or at least lots of time goes into those HPs.

Has anyone posted dyno results for about the same spec engine but with tri-carbs or such multicarb log thing?

The way is towards the new head designs. If only those guys get 'em priced to sell...
 
Great work mraley. This is gold!!!! Time to include you all in you own kind of Power and Quarter Room Sticky! There are guys and gals here who have been nice enough to give us timeslips, and post there power readings. We salute you all!


I am not at all sceptical, as anyone who pays for a dyno or timeslip has a legitamate claim to fame, and deserves free rounds of beer and life pearge in the 100+ Club!.


That compares with

There is basic info from Ak Millar on 65 rwhp stock with the 200 .
kastang's Mustang 2V at 105 hp in 8:1 compression 200 form with no mods inside.
Mustangaroo had about 105 rwhp in stock 200 2V form,
80Stang, you got about 100 hp at the back wheels in Gen 1 with just the stock bits mit good cam, and your site has great info on the Gen 11 engine.
MustangSix did some DeskTop Dyno simulations from 100 to 170 hp with various combos.
Hudson Nut into the 185 hp mark with a flattie 354 dueced Huddy six
Dynoed250 into 290 hp or more flywheel with his EFI 4.1
Does 10's into the 200's with his stock but cammed and turboed 250


There were others.



I've got all the most of the stock net flywheel readings and rear wheel dyno runs from factory Ford sixes, and 77 hp in petrol in my 4.1 XE, then about 100 hp in LPG before headers, so I'm not even close!.


I always take dyno readings with a grain of salt, becasue the calibration is critical.

In real terms, a manual will loose 26.5% power at the wheels with a set of 205 section tires and a T5 and 7.5 to 8" diff. The autos loose about 33% for a C4 and similar diff and tires.

The repeatability of dynometers is not that good unless the calibration is verified. Its easy to go accross town and gain 40 rwhp without changing the engine.


In Australia, Wheels used to have independent Dyno tests, and there were a wide variation, up to 65% less than the factory rate net figures, so its clear that any given dyno could be +/- 25% out without the owner knowing.

Again, just being analytical, not wanting to take an iota from your amazing work.

Michael, you da man!!!!!
 
xtaxi......Well, I didn't know I had elevated to such a high level, however thank you for the congrats. My stang is going into the shop next week to have my new oz head installed. I can't wait to go back to the dyno to see what gains the oz brings to the table.

Does anyone want to make a guess????
