hey guys,

just after some oppinions and possibly some help!

ive done a little bit of work to my car and have just had a recent dyno tune to find even on 14psi i could only bust out 207rwkw!


now for the engine specs:
(its a 93 tt factory 5speed)

3.5" straight through exhaust,stock dumps
fmic and cold air intake
adjustable cam gears
big fuel pump and 650cc injectors
microtech ltx12 computer and bosch coils
apexi avc-r

the car is built just for sliding,it makes great torque-pushing the 700nm mark,but to me 207 just seems low given how little mods a 1jz needs to hit the 220rwkw mark


and no the clutch isnt slipping!


any help would be great!

cheers
brendan

Maybe getting some bigger dump pipes would increase it, get a better flow.

i was pushing 207.3rwkw with standard dumps, FMIC, pod filter and 13psi.

It may just be running to rich with a big fuel pump and 650cc injectors

Yeah thats what i think aswell Luke, theres no need for a Fuel pump or 650cc Injectors...Id take it to another tuner and get them to have alook at how rich its running.

I would say that power figure is about right for the mods you have. I dont understand why u got the ecu / injector combo if you have only retained standard turbos. Also if you want more power from the twins, a dump pipe is a must. the factory y piece is so restrictive. this will push you to about the 220-230rwkw mark with the cooler and cam gears. This is all capable with factory ecu and fuel system. if you then want more look at turbo upgrades being either high flowing or large single turbo.

Anyway thats my 2c

theres nothing wrong with having a large pump and larger injectors,the ecu totaly controls the af/r and yes it is running slightly rich as it is for drifting purposes and running rich helps keep the engine cooler and stops leaning out at high rpm,i am a mechanic. the tuner is the same guy that tunes jay ducas cars(inc his 1000hp supra)and is well clued up on 1 and 2j's,hes also an authorised dealer of microtech computers so he knows how to fiddle with what i have.i am planning on going single soon,all the stuff i have done so far is just in preperation to the conversion.


thanks for the responses guys,ill chuck it on the dyno at tafe and have a fiddle in a few weeks

...

I would say keep it running nice and rich for circuit or drifting, but try adding some more timing into it for now and see how that goes.
