1G GTE Boosting late
|
Fri, 30 April 2004 06:06
|
 |
Another question about my 1G-GTE 
I have currently got a 2.5" straight through exhaust on my 1G GTE RA60 and the turbos only hit full boost around 4300rpm, does this mean i need more back pressure in my exhaust by eg using a baffle muffler or something??
Does back pressure in the exhorst help the car spool earlier but decrease top end power??
I just want to try get the car boosting earlier  .
Cheers

THE FREEER UR EXHAUST FLOWS THE FASTER UR TURBOS SPOOL UP
JUST CHEKT HAT UR INTERCOLER PIPING HAS NO LEAKS IN IT OR HASNT BLOWN OFF , AS THIS WILL CAUSE IT TO LOOSE POWER
MINES ON FULL BOOST AT 3000 RPM I THINK , AND PULLS 8-9PSI
EVERYTHING STOCK

Dude, turn off your caps lock key or everyone will think you're a moron who SHOUTS ALL THE TIME.
1G's can be safely boosted above the factory boost level, but don't go nuts or the turbos will have a limited lifespan. This has been covered many times before so do a search and you'll find all the info you need.

Factory dump pipe.
Stock 11psi (Gen 3 1G-GTE).
I know many people who run 14psi all day every day. I don't think you need to worry unless you go above that.

While you have the bonnet up checking the intercooler pipes, Check you ignition timing is set to 10 Deg! Amazing difference to be had when its all operating at the factory specs.

approx. 12 degrees ignition timing and the right mix of octane boost found me another 7 or so kilowatts on the dyno.... on standrad boost I was pushing 145kw at the rears in shootout mode.
mine has full boost by 3500rpm, starts spooling at about 2300rpm...

Another problem may be that the waste gate is stuck open (various reasons) but I have seen it happen because of custom dump pipe flanges running too close to the flap valve, another reason may be that there is no c clip to hold the actuator

but this is what i have otherwise
1988 model soarer 1g-gte of course ,
front mount air to air cooler
i put a boost gauge on it and got around 8psi stock
the car is still a stocker , nothing has been changed xcpt the wheels and spark plugs
also will my car run really rich if i boost it to 12-14 psi as all u other peple are doing
how ur cars running fellas , is it too rich with that much boost
cheers

A Gen 2 will make that sort of power at 14psi.

im makin that at 8 - 8(and a bit) psi, I have thought now that im a fucking dickhad because it may be that my taco might be out because of the conversion??? this could be why it is reading it hitting full boost at 4200....... i hope

4200 on an uncalibrated tacho would be 2800. Sounds about right. Maybe a bit laggy. Do you have a large i/c?

A six cylinder pushing 2800 revs will read 4200 on a four cylinder tacho. 
Apparently it's a $50 fix from any instrumentation place. I haven't done it though so I don't know for sure.

No idea, but I wouldn't think it'd really be worth the trouble/money.

piss the twins off and slap a single on there. if you've got the money. if i had the money i would. ive had problems with boost and all that shit, but i found it was the intercooler piping, so i fixed it today, i might be the only one who has tried this but has anyone put a boost controller to each turbo?? tried it on the weekend, went nuts.

i strongly recommend that you DONT do this i have designing and selling boost control systems for several years now .
the problem with doing this is it is almost impossible to set the turbos up so that they both make the same boost .
although you will see your desired boost at the manifold this does not reflect what each turbo is doing
even when putting a boost controller on each turbo and measuirng the actual boost from each actuator line you still get varitions in boost under different load situations
the rson it seemd to go harder is you have possbile either reduced or increased significantly the length of this this will change the boost surge rpm but not avtually effect performace at the same boost

7,200rpm would show 10,800rpm on an uncalibrated tacho.
As for the turbo. Do a search.

a TO4 should be a sufficient single turbo upgrade for a 1GGTE. I remember reading on here about some other guy that does mid 12s with stock ECU, stock injectors and a T04 on his 1GGTE RA28.

T04 on a 2.0L would be too laggy IMO.

actually stueys to4 powered 1ggte is not that laggy at all . in fact its only about 500 rpm more lag than roller bearing setups.
12.49 on stock ecu with low 8 sec 1/8th mile times ....
not laggy at all
i believe its on FULL boost by 3500 rpm with good boost response by 2500 rpm .
watching the video form ther toyota nationlas its a damn good setup with similar launches to stock 1js ...
contact JT mechanical in newcastle .he set it up

Or better yet, contact me, because I brought the kit in from Japan and sold Stu the kit. I get them in from Japan all the time, if anyone needs one.

fair enough !!the final turbo although was born on the bench at JT mechanical . with jamie actually using components from his own turbo to come up with final model .
The specs of which hes keeping to himself .......dont blame him either

Im pretty sure it is not that hard to calibrate a tacho, as know they have two wires coming out the back normally a brown and an orange one. Tahcs are normally calibrated for a V8 when first bought, cut the orange or brown (not sure which) wire for a 6 cyl and the cut them both for a 4 cyl.
