Hi Allan

Being a bit of a closet 7M fan, I thought I might take a different approach and offer a few suggestions in a vaguely constructive manner.

Motors get a bad name from factory weaknesses, malplanned or poorly executed modifications, poor maintenance, and well-meaning but misinformed owners. Unfortunately your car appears to suffer from most of these and would probably perform a lot better in near-standard trim.

Reallly??? well in standard form it made 129rwkw when i took it upto the toymods dyno day.
runing pig rich mixtures almost choked the dyno op up there
and the only thing that has not been serviced in this car is the auto trans as i have been waiting to fix a few oil leaks, other then that it has new lead's, plugs, filters/oil at every 5000km.

as for the rest of the car im doing things the RIGHT WAY it has basicly all new suspension (shocks, bushes, wheel barings ect ect (I.E. I dont thrash my supra while it sounds like the back wheel is going to fall off not refering to 7m-brizzy here) diff, rack ect ect. bosch motorsport fuel pump... thermo fans over $4k of recepts of parts so far, your more then welcome if your ever in melb to try and point out any of my workmanship that is sub-standard on any part I have replaced.

* second hand bleed valve, set to ~11psi: $25
* 3" mild steel exhaust: $930

you should of got a welder! my compleate stainless system only set me back $400ish and a weekend

I know your ego will take a bashing, but return the thing as close to stock as you can... give it a good service with colder plugs, run some real fuel through it, and stick her on the dyno.

I'm not really into dynos, but as this is your thing, establish a baseline this way. I can all but guarantee that you'll make almost exactly the same power as you are now. How do I know? Because a mate's Supra went on the dyno, with a mottled press-bent cat-back exhaust, an auto and 11psi.. and made 207rwhp. That, in kiddie language, is 153.33rwkW and near enough to spot on the figure you are making.

From there, plan some modifications.

THE ONLY "PERFOMANCE ENHANCING" THINGS ON IT IS 1UZ-AFM, AFPR AND BLEEDER

how much closer to stock do you want it??? look at the boost gauge video and see how much boost im runing! the thing only pinged MINORLY after 10 mins on the dyno and well and truely heat soaked, to make a decent ammount more power you need to do something serious with the intake air temps rather then bitch about 7 RON points

ANYWAY I plan to bring back this threed when i have a nice dyno print out of the 7m once i have done a couple of things (while retaining a CT26) to it and time slip to match

7 ron points mean a lot
go see how long ur car lasts with any sort of power usage with 91 ron
