Thought you dudes might be interested in this. Gave it a run yesterday. With the conversion factor used in Porsche Cup it works out to 238hp at the flywheel.

Nice looking curve Howard.
Can you elaborate a little on what you are running?
I'm curious as I will be running a 2.7 rs clone very shortly!
Glenn 73 914-6

Glenn,

2.7 twin plug, 10.5 JE pistons, S cams, Webers. The twin plug part was a lot of messing around but the result is worthwhile. It pulls so well from 2-3k to 7k. Its just extremely flexible and fun.

Yawn.
Just another POS 2.7L, eh Geoff.....Geoff?

Good job. That's mo power than I was WAGing from mine.

I saw the AX video. I like the way yours goes. I take it Geoff doesn't like 2.7's for some reason. They just have to be put together correctly.

Howard; we have very similar engines. I thought I'd post my dyno run from a while back for you to compare. They printed a test run and first pull on the same sheet. My engine is a 2.7 twin plug, S cams, 11.5:1 Mahle pistons, Electromotive crank fire ignition and Webers. Everyone I know says it's the sweetest sounding engine they've ever heard. I think you're going to be happy with yours.

Woo...some nice numbers there guys . I can't wait to get this SDS stuff jammed in my engine bay to get some dyno numbers of my own. Anyone know a good conversion factor to get FWHP. I'd guess it's pretty low, like 15% or less. Has anyone done both engine and chassis dyno on the same engine? Jake?

Nah, I got nuthin against those whimpy thermoreactor cooked 911 engines.



Geoff

how, are you going to show us picture of your car with the sticker in the window? the only out of country car i have seen with one is beno's? you canucks too.

I dont think you have lived until you have driven a car (911 or 914) with a strong early 6 in it... Too me there is nothing like it. I drove around a 72 911 with a 2.4T in it for a year, it had MFI and when it ran right it was incredible. 2.7RS spec would be very similar especially if you made it a REAL RS spec and had MFI.

I kinda know what you mean, but I was spoiled with the larger sixes and just cant get used to those old peaky motors. They are fun to visit once in a while, but to me it would be annoying having to keep the revs up to have any passing power.

Nothing beats cubic inches (or cc's in our case).

Drew, thats a serious amount of grunt. I assume the run was in 4th. What size tyres do you have on it?? I friend has bretty much the same spec engine in his 911 but with more comp and MFI and he's fetting around the 190 mark.

Kevin, I'll take a photo as soon as I get some light. Its 5.00 am here. I woke up early!!

Kevin,

Here's a couple of pics of the sticker.

another

Forgot the pic

I hear Andy take shitty pics!! did he take those pics LOL

focus man


nice dyno sheets though

Howard; everything is a little fuzzy right now, but my street tires are 245/50/15. The operator did the dyno pull, I assume he was in 4th. I have SupperTrapps and got different results with no disks. I want to go back and try it with about 5 disks which should move the torque lower in the rev band.

I didn't realise the photos were so shitty until I saw them on the board. I will get some better ones.

On the dyno it was doing 184 kph at 7300 in 4th which is about 114 mph.
