The biggest issues with engine dynos is that, unlike a chassis dyno, the mountings are engine-manufacturer specific. So in order to make a Subaru engine fit, there will be the need for a custom bellhousing adapter and engine mounts. I had mounts made about 15 years ago for an oddball engine I was developing for SCCA GT-4 racing, and the adapter alone cost me close to $800. Bob |

I couldn't agree with you more. I believe Boxer6 is working on setting up such an engine dyno at his shop. This is yet another reason why I said that that next year should be eye opening. -Bill

But the percentage of gain is real. 221 whp to 285 whp. I have to corner-balance/scale this car on Sunday, I'm *hoping* to get to actually drive it too. Bob |

Hey Bob, I can not elaborate as to how weight would affect things on a Dynapack dyno. Most of the SVXs here at the site have dyno'd using a Dynojet dyno. So what I am saying is that people should not expect to see these same type of gains with the same modifications to the engine as yours, on a Dynojet dyno. Weight is one of the variables that will throw the differences off. Autotranny, different type of dyno, etc are others. At any rate....the numbers are good.

I think the point is that weight shouldn't make a difference with the Dynapacks as they bolt right to the hubs (?). The only variable should be the parasitic loss through the drivetrain to the hubs (AT vs MT).

I think Kevin is saying that even if you got the same HP in a SVX, it would not get you the same results at the Track, nor on th estreet, as the SVX is just a lot heavier....
But it WOULD make it a lot faster than it was without the mods...

The same event that I rode with Jack I also rode in a slightly tweaked Sti. Interesting diferences in the handling. Jack could get easily get a little bit of rotation to help his cornering. The Sti was noticeably pushing in all corners. The Sti clearly had more grunt out of the corners, but I bet with the new engine mods, the RS will really be a contender. Will report back any sightings or, hopefully, rides, during the next few months.

Weight should not effect results using any form of wheel dyno. Weight being factor which affects acceleration, rather than developed power. Hence the disparage in respect of quarter times verses maximum speed, recorded for the SVX.
That said, tyre inflation is a very important component in respect of error, made more, so the heavier the car.

A small update:
I had to corner-weight Jack's EG33-powered Impreza today. I had hoped to get a drive in this car today, but it was not to be. Instead, Jack did take the car out on the road for the first time today. I told Jack he needed to test-drive it to make sure the tune was good. Yea, right, I just used that excuse because I wanted to hear it go through the gears.... All I can say is: I wish I had a video camera today, so that all of you could hear and see what I heard and saw. The road was damp, the tires were just normal street tires for the road-test. Jack violently side-stepped the clutch, and the car literally smokes the rear tires for 20-30 feet. The front of the car unloads with the front tires scrambling for grip as well. He is shifting at 8200 rpms, and he says it is still pulling at those rpms.... Keeping in mind this is on a Sunday in an industrial park area, the otherwise absolute silence is only broken by the sound of a very pissed-off EG33 echoing off the walls of the vacant buildings along the test road. I cannot *quite* explain the sound. Previously with bolt-ons, the car sounded like a very healthy Porsche flat-6. Now...I don't know, it sounds far more mechanical. There is no transition from 'street' to 'performance' like you'd hear with a modern 'VTEC' style engine. Nor can the cross-over flap be heard anymore as an increase in induction noise at a given rpm. It sounds viscious from off-idle, but the intensity grows as the rpms climb. It sounds purely like a racing engine now, there's no other way to describe it. A cross between a Porsche Carrera GT and an Enzo Ferrari is the best analogy I can make. It almost seems to have gained a few cylinders. I'd like to apologize about my previous inaccuracy about the NASA racing weekend at VIR. It is coming up this weekend (22-24th), not at the end of the month.

what valve springs do you have on the motor again?

BTW.... Major props for this car.. I am very interested on hearing quotes for a stand alone installation in my new ebony SVX
