Hey, Moggy! Dyno pictures

Hey, Moggy. Hope your engine is running well. I tried to find those pictures of your dyno HP curves, but can't locate them on the forums. Can you please post them again? Also, were the numbers from the rear wheels or at the crankshaft?

Regards,
jay

Hey Jay,
here is the link to the dyno numbers:

I'm getting a woodie thinking about this project

That is with a supercharger right?

Yes, sir, supercharged nearly stock 2.4L with 104mm pistons and cylinders.

I love the torque of that monster. Mueller and I are figuring out if we should install our Eaton blowers.

Mighty tempting. I am just trying to figure out if I will go with supercharger and A/C, or just supercharger, or sell my 912E and buy a 911 Turbo.

Some say the hub to crank connection isn't strong enough for the supercharger and A/C. I just don't know.

Jay,
What do you mean "if" we should install them?

I didn't get the darn thing to be a paperweight !!!!

I have to focus on rebuilding my 2.0 n/a motor, then I'll start on the supercharged 1.8 motor.......after reading Moggy's post about his M45, I think I made a good choice in picking the bigger S/C of the two.

I will use an M62 I think, if I use an Eaton blower. I have not decided yet, I want to get my 2599 finished and tuned properly then determine if I need more horsepower!

I am going to turbocharge the baja bug first.

Did you see this months Excellence magazine article on the TPC eaton blown 993? We had more technical info from their webpage than the article included, good pics though. They used the 90 model on the 3.6 liter.

Jay, could we have machined chromo steel super dooper strong crank hubs? Or is the crank the weak joint, not the hub?

Moggy, are you going to be racing at Bug Jam next weekend? I'm hoping to see you get that motor well and truly sorted at last. Would be nice to go head to head when she's running real nice...
By the way, I've finally got some slicks and a spare set of Erco's for the rwyb...he he he

Yeah, I saw that 993. For some reason, it doesn't appeal to me. I guess I have always seen turbo 911s, and they rev so easily, the turbo and engine are complimentary.

Ya know, I don't know anything about the hub to crank connection. All I know is that the machine shop presses that hub on with the bearing. I have no idea how strong it is or whether it can be strengthened. That looks like a good engineering challenge. Figure that out, and all is well. I have a spare 2.0L crank outside. I will have a look-see tonight.

You are the engineer here Jay, I have four years to go!

Steve, I'm a Civil Engineer!!!

If I could make the hub out of concrete, rebar, and 2x4s, it would already be done.

Sorry guys, been on hols for 2 weeks in Greece had a great time, forgot how good holidays could be.

Anyway, the latest on the motor is I've been running it now roughly every other day to work and back and round and abouts. And so far no major probs, minor probs include the exhaust for some reason decided to move closer to the crank pulley on a long journey and started rubbing on the pulley (solution bent the exhaust out slightly to clearance it - solved).

Now I'm happy with the fact that the whole set-up works in principle it's time to move to phase 2 which is to get the most power out of the motor. This involves the fitting of a water to air incooler (from Pace products - 3 core unit) which they say will garuantee to keep the intake temp to under 30 which will enable me to do 2 things increase the advance and inscrease the boost. Which will increase the power two fold, not only due to the increase in boost (and to a small extend the increase in advance) butdue to the cooler air hence increase in charge density which also results in significant increase in power. However the charge cooler will also sap 4psi (approx) which means staying at the present pulley ratio and EatonM45 would result in a effective boost of 2psi (ooooohhhhhh!!!!) so the Eaton M62 is needed which will be ratio'd for 14psi resulting in an effective 10psi boost.

So some fun times to come.....

The dyno curve referred to above was at the flywheel last year.

MATT - Yes I'll be at the Jam but due to hols and just buying a new car (Chrysler PT Cruiser) I'm skint so there's no changes to it since I saw you at N Weald, but look forward to seeing what your beast can do with your new goodies, hopefully you can get those 60ft times down. See you there this weekend..
