My point exactly but I'm not goign to call anyone out on their dyno numbers.

Like I said, the DYNO almost always reads higher than teh trap speed dictates it to be.

at 3305 yours shows 345hp

Sorry,just interested in the power curve.

Right in the ballpark.

Temp / altitude / etc affect numbers. I think bandimere is somewhat higher than longmont. Could have been a hotter day too.

I would say +/- 10hp is reasonably good.

So sorry Rod. I'm just used to these dyno debates I guess.

I'll get one pretty soon. But I can promise you this; it will not look anything like a Honda or DSM. Considering I ran 115 on 12 psi (which is around 370 hpish probably a decent amount over 400 tq given these cars) and I hit 12 psi just after 3000 rpms the torque curve should be pretty flat.

That is one thing I will give up to a dyno. Adjusting timing and AFRs to help torque curve.

I think for me a "cheap" way to gain some extra speed is a few things:

Loose 100lbs of dead weight in the car. Unloading trunk = free. Probably some lightweight seats instead of the million way adjustable recaros would help.

Beyond that I need to try harder to lose weight.

Then I think my next limit is fueling. I think I am maxed out on stock pump. I could increase fuel and it did not richen things up. To take of this issue...i have a -044 fuel pump on my desk here in germany that is coming home with me (this should be FUN with tsa. A vacuum packed device with some oil surrounding it in the package)

Then I want to get my E85 / gasoline drivevability issues sorted out. I have no drivability issues with gasoline, E85 and I am always screwing with it to keep the AFR correct.

What has piqued my curiosity is the zeitronix E85 analyzer. It outputs alcohol content as a voltage and fuel temp as voltage. Adding this seems like "holy grail" of real world E85 street for us.

I'd say very good considering what you see out of most. He is obviously pretty well dialed into the air here.

I personally think you should talk to Josh. He has it pretty well dialed in. And you can use my lean burn maps and get over 25 MPG too on the highway.

I never have to touch anything for driving around. Actually I hardly mess with anything at the track.

Actually Sid, I'm very pleased that as a sideline to your drag racing you've discussed power figures that correlate to mph and more or less render dyno chart numbers obsolete. To add, what would be more interesting is to compare various charts to those that have actually done a few 1/4 passes and see just how much variation they get from their dyno figures. I would like to add to the data but certain actions have caused delays. I'm curious as to our dyno figures down here and just what mph our cars would do.

DanaT

Here. I thought I would post a dyno graph that you can directly compare to what you are used to seeing. This should make it much easier to compare American and Australian dyno charts to one another.

I am looking forward to see how far you push the envelope Sid. I too am planning a 3+ Liter build based around your design concept over the winter. A bit tamer version for sure.

Also, I would love to see a dyno sheet on your motor just for comparison reasons. I have no doubts that your car makes incredible power, you has proved that. I would just love to see the torque curve.

By the way, what are you doing then with your current 2.8L? Selling it, converting it, or putting in something else?

Dave W.

wow, those dyno charts from 'down under' are a little difficult to read!

On a serious note, I like your bore/stroke better. 103/93 works better for turbocharging than the stock 100/76.

I think you're giving up some power with the low comp ratio given the high amount of timing you're using, and the late spoolup of the turbo, and the raised rev limits.

Tom M'Guinn

What do/will you use for ignition?

Trust you know you need to be careful about getting oil to the lifters with small base circles.

Stock headers and intake?

Any plans for stregthening the bottom end -- things can get squirrely down there at very high power levels, especially if you wil be racing it and not just doing a few dyno runs at that level. There are some lower stud options out there...

SId, not to throw you off, but I completely agree with your horsepower calculation statements. LOL!

Sounds like a solid dragstrip motor Sid. I have no doubt you'll make the goal.


Patrick.. That was hilarious.
