ilovmel, jjohnno - All cars will read different figures, even on the same dyno. It all depends how healthy the motor and driveline is. With a locknut's 117.8rwkw, I would say that it is a very healthy EA!

With a car that has the a*** flogged out of it, it may only pull around 90ish rwkw.

The only way to know is to actually put it on the rollers and see what she makes Because just guessing is useless!

going by the temps on the bottom of the graph it was a pretty cold day which will always return slightly better figures.

dyno's are a tuning tool only. dyno figures can only really be compared to other cars run on the same dyno on the same day. most decent honest operators will be within coo-ee of each other but most arguements are settled down the strip.

had to be said

sweet might have to hit him up for a go on it .

For sure man, will let ya kno when the next dyno day I hear of is on.

I'd very keen to see what rough exhaust alone give (snorkel or not).

I will have mine done by next dyno I hope, so will have a fairly good comparison.

Hey all, been away a little lately, but I have the newest dyno results. Previous runs were with the EA stock as a rock with a new head and valves. The runs were with airbox (stock) 114rwkw, and airbox removed; 117rwkw.

These new runs are (on a fkn hotish day) with my trusty EA running 4499's, small hi flo cat, lukey 2.5" twin muff sys. As it's a dyno day, I got the highest of the 2 figures without the airbox. 127.1rwkw (XH Snorkel and K&N Panel fitted), and 130.8rwkw without the airbox.

The guys were impressed that it's still running awesome Air/Fuel. Everything sounded nice, and I like to think of this as the "textbook" EA to compare mods Vs gain on. I did want another print out.. Street Trim Vs Street Trim, ie: 114rwkw Vs 127rwkw, but it didn't happen!

Cheers..

Wow...nice figures . Looks like you'll hit 150rwkw with a new cam mate. Keep us posted

phong =P~

i have an official ford spec sheet here that might help (printed october 1989)
if you want it scanned let me know as linux has an issue with the scanner & will need to switch os's.

standard power figures are as follows:

3.9 EFI (EEC 4)
Fuel (Octane rating) 91-93
Compression Ratio 8.8:1
Max Power DIN kW/rpm - 120/4250
Max Torque Nm/rpm - 311/3250

3.9 Multipoint EFI (EEC 4)
Fuel (Octane rating) 91-93
Compression Ratio 8.8:1
Max Power DIN kW/rpm - 139/4250
Max Torque Nm/rpm - 338/3500

Thats a healthy figure for a un-cammed EA.

Got any plans for the 1/4 mile?

Yeah, cheers. Am already aware of heaps of figures for cars in general, I see now why you posted this.. I just meant "textbook" in the sence that, I got the gains that aftermarket manufacturer's claim from their products, and that my EA (whilst it's only a sh!tter) is such a nice and simple example to experiment with modifications and dyno'ing on. Cheers tho.

1 other thing, cuz I have grown up a bit, and the fact I race 1/10 R/C (which teaches you: 1) make it handle 2) make it fast) I've modified this car in what I believe to be, a sensible order. Shocks and coils first, then the others. If anything, I should really get new discs and pads next...





Yeah one day after the 1636 cam finally goes in.. I hope to bust into 14's. Fk I wish there was still a dragstrip in ACT. I've only been here 2 years, but I heard there was one a few years ago. I think Wakefield has a 1/4mile strip? Or is it Eastern Creek?

Also hope that the Wade Cam and maybe some ignition timing ad's another 18 - 20rwkw, and puts me over 150rwkw in an EA.
