I believe there is ~40hp diff between the NA and turbo's AND turbo's love to pull on hills; I wouldn't expect the .910 to keep up with the .962 in that environment, expecially as your .962 is chipped.

How does th biodegradable harness look?
The throttle kicks down at lower speeds when the accelerator is pinned, its just uphill going 65-70ish at 3400 rpm or so that the car seems to lose steam. If I downshift to 3rd the revs climb, but I would rather have the kickdown switch do this.

I am very surprised by this car, I like it even better than the 606.962, it seems quieter and more refined. It feels more like a refined 617.952 as opposed to a 606.962. I will take a look at the resonance flaps. I am still a newb with this motor, but it seems like its a tad more complicated than the .962 (with all the linkages etc).

The Harness looks great, it was definitely recently replaced.

You should think about removing the intake manifold and cleaning out all of the crud, then block off the EGR valve so it can't crud up the clean pipes.

Jeremy

I plan on blocking off the EGR, but I would like to make this mod look a little more factory like. I am still trying to figure out how I would like to plumb it (not a big fan of the heater hose with filter at the end). I am looking for more a less a factory look (perhaps I should run it back to the air filter box? Not sure still working out the kinks.

If you floor it from a stop, at what rpm does the car shift? It should shift somewhere around 4800 - 5100 rpm. If not, something is restricting fuel flow.

I would have guessed your issue is fuel filters, but you said you changed them. If you do take your manifold off, change the plastic fuel lines as a "while you're in there" thing. If you see bubbles in the fuel lines when running, you have an air leak somewhere.

The yellow film is "cosmoline" or whatever they put on your car new to make it look nice, but it yellows on age and is very difficult to remove. BMW's have the same thing. Unless you are a detail person I wouldn't fuss with it.

About the vacuum line, on my car there is one "tube" with 2 lines in it running behind the dipstick.

I cleaned the IM when I first got the car (it didn't have too much crud, just a light dusting of sticky soot). I also inspected the fuel lines, they looked clear and did not leak. I noticed that the PO used a smaller fuel filter than the bosch ones and I replaced this with a bosch fuel filter along with the pre-filter. At a stand still this car feels pretty quick, its just at higher speeds going up hills where I notice a huge reduction of power (70+ MPH up-hill it stops pulling).


I hate that yellow cosmoline stuff it makes the engine look unkempt.

On my car the vacuum line has a tube and one extra line bundled next to each other. It seems like there could be a chance that this vacuum line could somehow get disconnected and make contact with the fan.

There is a clip on the front of the engine block that holds those vacuum lines close to the head and away from the fan.

Cosmoline is applied to a new car by the factory to protect it from corrosion, not to make it look nice. Kerosene or biodiesel often get it off, but not easily.

As the others have said, your car should be performing better.

Good luck, great car.
The car pulls a little better when selecting the gear manually, but it still runs out of steam way before it hits 4500 RPM.

I have seen some cars on EBAY/autotrader etc that have clean engine bays, I am thinking that this will be my next project to tackle.

Thanks I love the car and this motor I just wish the top end could be improved a bit more. I am thinking I should get the Speedtuning N/A chip for a little increase in power. Has anyone gotten this chip?
