off to the dyno today

[525gte]

going to be good day also not so good, was unable to get a working set of 440s in time. so i have to dyno on my stockers.
also going to get tuned while i am their. ill post numbers later hoping to see close to 400 maybe 380. that will be a good base line.

Without knowing your mods I will just assume that you are on a stock setup. With that in mind You would have a better chance of winning the lottery than hitting those numbers. Again that is assuming you are stock. Good luck though and I hope it posts way higher then expected.

i predict 295-300 with 370s

 

[IBoughtASupra]

350

 

[525gte]

sorry bout that was driving.
bc2 cam
single turbo
3inch exhaust.
sfac2

ended up making 313/281 could not boost past 14.6. may have a leak that i over looked. i have 440s but 1 bad one. my goal is 400 so i have work to do to get their
and some mild porting im going to try to post dyno sheet

i think i would have made 350 also if it was not for the boost issue.also ignor the dyno grph boost level, it is not correct

 

[IBoughtASupra]

Porting what?

Smoke test the system and make sure all of your clamps are tight.

 

[525gte]

Mild head porting. Going to do that prob later today.

 

[IBoughtASupra]

So you just dynoed the car and you're going to pull it apart?

 

[Devin LeBlanc]

nah, port it with the head on the engine Who needs flow bench testing? Just grab a dremel and make everything bigger!

 

[525gte]

No lol I already did the porting. I'm going to pressure test the system to ck for boost leaks. I prob will not dyno again or tear into it till after labor day. I want to enjoy it for the summer.

 

[IBoughtASupra]

OOOOOOOOOOOOOOOOOOOOOOOO.

Okay!

I agree about enjoying it for the Summer.

 

[525gte]

So. I found of of my issues I had a massive boost leak. It took 30pounds of shop air to get my gauge to read 7 psi.. don't know how it was overlooked.. but shit happens. Fixed now

 

[IBoughtASupra]

Get back on the dyno!

 

[525gte]

No 2 months or so. I want to get my injectors inand a couple other small thing dones

 

[525gte]

back to the dyno today. car made 21.5 psi runs great no knock good fuel. . andno leaks.. all issues fixed and here is the resualt . i will post up the whole graph once i get it emailed to me

Is that with the 440's?
What muffler are you running?
I have an 88 750il and would never attempt a swap in that. However,the 750 and 850 both use a hydraulic brake booster that runs from the power steering pump since you had an issue with the vacuum booster.

yes tht is on the 440cc.. and the onlu issue i had with the booster was intake clearance. but its no big deal. going to build new intake next winter. and i am running the toyota ps pump so i dont think that would work, but it is a good idea.. its funny i asked that question on the bimmer forums about running a different booster. and did not get one answer.lol but i got a bmw answer on the supra board. haha i was able to lower the motor down, and dent the booster just a little to make room, but thanks for the info..
and i am running 3 inch all the way back and a dynomax zt i think it was a zt.. with the flap in it. nice and quiet driving down the road. get loud under gas

Aaron told me that the 440cc JDM injectors when he flow tested them, they flowed close to 480cc.

I would belive that. I will look later but I have to pull a lot of fuel out like 20 percent. And every system is different. Butwith more fuel pressure u can make them think their bigger and I'm on stock fpr.

The hyd brake system in the 750 , early 735 and 850 would be to complicated to install. Besides the master cylinder with "Hydroboost" and pump (two versions, 735 and 750 had self leveling rear shocks, 850 normal) and a 2 part pressure regulator/accumulator. The accumulator or "Brake bomb" holds pressure to allow you to get about 10 good pumps from the brakes with no hyd power. There are also pressure switches on there. If you could get it to work it might be "The Bomb"
