Been told the Adjustable Eclipse cam gears fit the 3.5L SOHC.
Ordered mine over ebay US and saved almost HALF of what it was to purcahse them in australia.
exchange rate ftw!

I hope your torque at the flywheel isnt 230nm as being a TH it should be 300nm stock

As it's I'm hoping at the wheels, you better not change tyres or pressures during your mods as the torque at the wheels will change accordingly

[wookiee]

assuming that your power train loss is linear, you are understating your flywheel power after the exhaust mods by about 4kw. should be 164kw.

on a side note, I'm impressed by your power train loss (or lack thereof). you're getting over 76% (only 24% loss) of your flywheel power at the wheels!!

that's as good as some manuals!

cheers,

ill have to check with the issue with the torque, but for the rest of it i was pritty happy with the car, it had a noticeable difference, well i spose i would think that after the way she has been running. anyways to state the obvious = means accurate, ~ means approxmate. i hope this helps anyone who wants to do some modifications to there car.

thats a good power figure for a practically stock engine

interested to know what you get when you go to stage 3!

good stuff

[Gerard]

im very impressed by the power increase with the exhaust setup

keep the updates. and yea, i really wanna see what the manual difference is.

once u finishd ur mods you should be proof that its less expensive to mod NA than to get the sprintex super charger ...u have 7 k to play with

true, you can get some nice figures out of N/A.

Nothing like a free spinning engine for a bit of fun.

But for $7,000 can you get a N/A to >420nM and 225kw without increasing CR?

awesome stuff mike, should be good to see how the other mods go

also for the others, bear in mind its a hub dyno, may have some effect on drivetrain loss (havent read into it, but i know theyre different to rollers)... main point is seeing the power increases, not what the actual power figure is
