No worries mate.

And for the other guys saying you cant use a measuring cup to flow test a jet?

Ill go do it right now if you like. You run your WI system as per normal. Just point the jet into a measuring cup and switch the system on and let it fill up.

And obviously the system will be pressurised? Thats what the water pump is for.

 

would pre-turb. AI work to make boost earlier in RPM.
i got a 1.8L turb diesel Isuzu coupe, its got a Garrett T25, and it takes to long to make boost,,
once its up on boost it makes more than enough pressure. im lookin for pressure down low, not so much at hi rpm

i know off topic ,BUT!!! any ideas

 

alls i have is the jet. nothing else. so i i can't pressurize with alike WI setup. i could rig it up to the air compressor though.

 

In my experience it won't . Put a bigger exhaust system on, a better turbo manifold, and a bigger ignition system in...

 

I dont believe it will.

 

rx72c your killing it out there, you have me wanting to to try this one day also.. good luck with it all and man your setup, it looks good ttyl

 

thanks mate. give it a go mate. Its not magic.

 

So I guess the bar has been set for water, where are the straight meth guys?

 

converting to water

 

All this talk , and that silly old bastard Ricardo, did all the R&D back in the 1920-1930s.

WATER,, go figure,, I suppose some day we will catch up!!!!


My opinion is ,,,,they (oil companies ETC), wont teach knowledge in tech schools.

we end up learnin the hard way,, blowin a lot of motors!!

 

HEY! 1revvin7, what kind of ignition for my isuzu diesel?? LOL

 

Wow - only 2 degrees advance on the timing?

I've only had cars up to 20psi of boost and I think we were in the 12 range. Different ballgame, I know.
Did you base your timing off of EGT's or from power output on the dyno?

Really nice job!

 

could be 2 degrees total advance, which may translate to 7 degrees advance on your ECU if set at Mazda factory -5 timing. That's something that always confuses me, whether people talk about total advance, or input advance.

 

When i say 2 degrees of timing i mean 2 degrees at the pulley at self. So yes on a microtech. 7 degrees on the ECU.

When you have an engine that breathes well. Youll find it does not require an agressive tune to make lots of power. Engines that requires lots of timing to make power usually have a restriction. I had someone tell me this a long time ago and i never understood it. But after porting my engine a few different ways, doing inlet mods etc. It made sense in the end.

EGT's have little influence on my tune. I simply keep mixtures very rich and very little timing and listen out for knock.

I have had engines blow up with sub 900 degree celcius egts, yet my engine on a highway run will see over 1050 degrees celcius and still has good compression. That tells you something.

 

What device/brand sensor do you use to pick up your knock readings?
Thank you..

Very impressive car!!!!

What size is the hotside (a/r) on the turbo?

 

Dudemaaan, do you have a one way valve between the intake manifold and your water tank to keep the tank pressurized when boost is to low to be effective?

it would also reduce the 'effort' to refill the tank again whenyou're not using it.

Kind off reverse blow off effect let's say.

 

No i didn't add a check valve. Reason is because I have my pressure sensor coming off the tank for easy testing purposes. If my tank was always pressurized it would constantly flow. That is a good idea though and I considered adding one. If i ever get around to adding a second boost gauge to the tank it would give me a better idea of pressure in the tank vs boost pressure. I do however think that the tank pressurizes pretty quickly even without a checkvalve

 

This is really making me want to remove my tap before the throttle body and move it into my filter...it would ease my mind when I ramp up the boost to 20 psi.

And this is making me think of "street" legal mods too. Stock turbo, stock tmic, pre turbo injection..I wonder what I could put down. With no AI I put down 220rwhp at 12 psi..any higher psi the car felt slower due to heat, but with preturbo injection...I wonder.

 

how much power is the GT35r making at 30psi??

 

well done on the zoom feature dude

 

Damn 1 good Thread Finally =)

 

Thanks ash. Yeh its a good feature. I was happy with the way it turned out.

More videos coming soon. Promise.
This time will use better streets and do some 5th gear pulls.

 

Tuning at 180mph? Haha, I thought 4th was bad enough.

 

I wonder how well this would work with the twin turbos?
