Hey guys, just finished up a Supra project. I know most people are having a hard time swallowing the high pressure capability of the new Injector Dynamics injectors so I thought i'd put this up.

This setup was built around maximizing the power capability of these 1000cc injectors. We used dual Bosch 044 pumps in the tank with pickup adaptors from Kinsler fuel injection (thanks Scott!). The Bosch pumps are great at high pressures, up to 140-150psi. We ran dual feed lines up to the HKS rail, with the return coming from the center (pretty normal in the Supra world). We also used a high pressure Weldon fuel regulator (thanks again Scott! lol).

This is a 100% stock short block with 101k on it. The head has been freshened up and new springs and retainers installed, but no port work. The turbo is a Bullseye Power S374R and the manifold is an HKS divided. The car runs a Motec M600 ecu.

These runs were on VP Q16, which is oxygenated and generally requires about 5% more fuel volume than C16. As you can see by the logs, there is quite a bit of duty cycle left to go. At these pressures, the recovery time on these injectors is very short and the maximum safe duty cycle is 95% at 9k rpms. Keep in mind Supras are not as efficient as Hondas. I'm confident this same setup on a Honda will make over 800whp while maintaining factory driveability and idle quality.

I have some video at the shop that I need to put together and upload, the pics will have to do for now.

 

Some would say T-unit is the bomb and I conquer..

 

why is the torque crossover under 4k rpms?

 

I moved the scaling on the sides, you'll see one side goes to 1100 and the other goes to 1500. This made is easier for me to see what I wanted to see during tuning and I forgot to change it back before I printed it.

 

cool, just wondered what was going on

 

900+whp, wow! I guess supra guys are still using the rule of thumb of "get the biggest turbo that fits between the motor and shock tower" lol, very nice!!

 

Thats SICK!!! All that on with a stock short block 100k mile supra with the ID 1000cc injector and still a good bit of duty cycle left (none the less on a fuel that I would think eats it up).

Is there any limit to what you guys can do...

 

Holy crap ive never even been in a car that fast......technology is really coming on strong, loving it

 

so these 1000's, and a base of 100 psi, a reg that can handle it, can make over 800. nice.

do you think pushing a weldon db2015a to 145 is safe? at that power level?

 

Tony, what FPR's do you think are suitable when running these high pressures? Alot of people have issues with the AEM's but I have never had one and this is my 2nd one, but I think mine will junk out at 100psi base. I am about to sell my RC's and go this route I just want to have everything correct the first time.

Aeromotive?
Fuel Lab?
Magna?

 

The Weldon 2015A is rated by Weldon up to 160psi. They always rate their pumps on the safe side. They will usually do at least 20-30% higher than their rating for short duration.

 

Weldon or Kinsler on the fuel regulator. They both have units designed for this pressure.

 

nice so if i max out my 1200's i have another option. thanks man. man that sounds so wrong.

 

The aeromotive pro series regulator can handle 100 psi base fuel pressure. By accident I ran our CRX at 90-100 fuel pressure once with dual bosch 044's in parallel and it held fine. The car was breaking up down the entire track, but that is another story.

 

Nice!

Did you post this on Supraforums?

 

Sick.

 

The kinsler unit is so nice and tiny too!

Tony and to Scott @ Kinsler

Buy stuff from these guys for world domination

And that kind of power on a 101k stock block...we are all in the wrong cars haha

 

Gotta love these new Bosch injectors!

 

lol, yeah go and downgrade to 1000cc Bosch injectors

 

could not have said it better...lol.

 

T1 ftw always willing to share info!

 

great numbers tony Im sure augie is in love with it.

 

Great info as usual!

 

We got these injectors in the other day. We're super excite to try them out. Thanks Tony!

 

tony when you get chance put up the vid of this monster.
