i started to read this..... and found myself not being able to stop reading till the last page.... HOLY **** is all i can say

 

"did you ever get any whp numbers for that borg warner "

Aaron i am expecting to get the car up to Green Bay tomorrow or friday and the Borg Warner is first up.

i was able to get out and do some very modest logging since wisconsin is pretty (amazingly) free of snow. nothing here is too unusual but i thought i would share the data.

this was really my first outing on the newly put together motor and methanol setup i took it easy as evidenced by my 1.8 TPS voltage, 4.6 being full throttle.



since i replaced my entire FJO methanol AI setup w two additional secondary injectors that deliver the methanol my base fuel table under boost needs to be cranked up a bit. i did a couple of modest boost runs and used the auto-tune Excel calculator to zero in on AFRs.



my top PIM reading was 19744 or 13.3 PSI



i run 43.5 psi base fuel pressure and i log FP you can actually read the boost from subtracting 43 from top fuel pressure. note in the previous Mapwatch cell P7 N10 is 10,363. that is pretty much current pressure which is 10,332 at sea level.

check the same cell in the Fuel Pressure map and you see 43.7. my target is 43.5 so it is on the money. now look at the top PIM tick, 19,303. that is 12.7 PSI boost. and fuel pressure is 55.8 - static 43.7 or 12.1 so it pretty much matches boost. 'beats guessing if your filter/pump is up to the task.



of course the really new new deal is the fuel injected, Power FC directed AI system. believing that instrumentation trumps luck or genius i log pressure in the meth system. the EV14 injectors can handle 8 bar which is 8 X 14.5 = 116 psi. i have the pump set up to come on at 1.5 PSI boost. my pump runs thru a Weldon adj pressure regulator (w a return line to the meth tank). the regulator is boost referenced. so here's a log from my first run. it does show somewhat non constant pressure which is due to the pump impulses. we could add a surge tank to smooth it but i am going to forget that ATM and feel it will be just fine... i can/will do a touch of adjusting on the pressure before the dynoing begins.



my EGTs look quite normal at this modest boost/power output level. they should end up around 1750 when we get really rolling. a key to midrange performance/tuning is to tune up so your EGTs are in the 1400s from zero to 13 psi boost. it motivates spool. don't forget mid range.



knock is pretty much typical.... the methanol makes knock go away.



here's how all the factors relate.



maybe i get the car to Green Bay tomorrow if i can find a way to get home... otherwise it snows immediately thereafter and it will have to be trailered.

Very cool Howard. Giving you a call tomorrow.

This is about to get good.

 

^ ineed it is!!!

 

Glad to hear it! I will also be taking my borg s362 ett with a .91 hotside to the dyno hopefully by the end of January. Im scared the .91 hot side will be too small but i tried to balance it out with a full 4in exhaust. My manifolds runners are round 7 inches long. Although this is on a ported 13bnot a rew.

 

winter closed in a couple of days ago. we were set to make an early morning dash friday only to find that BR was closed between Christmas and New Years. the car will be trailored this coming week.

just returned from delivering the car to BR. dyno next week.

Luke was dynoing a really nicely built Porsche 928 w twin turbos running 93 pump and meth as AI.

funny thing, after a few runs (around 750 SAE and 680 Tq) they decided they weren't getting meth.

after checking they found the Snow meth controller was toes up.
i asked to see the meth pump relay and surprise surprise no diode or resistor.

maybe the relay thing is like the cold (i currently have) and is contageous.

Good to hear your back up and running. Can't wait to see the Aspec 3574.

 

read the entire thread.... i think i would have given up by now on the car lol. when its running and tested this needs to be at the least featured in a magazine.

i am waiting on the final verdict of the manifold and downpipe....

 

Hope you're feeling better Howard, looking forward to your results.

 

looking good

 

just talked to Luke and due to the thur/fri snowstorm we are set to go Monday am.

first up Borg Warner, second is GT3574.

probably third is my GT4094 and then it would be great to compare the Forced Performance w the billet 4094 comp wheel in the GT35 frame. that could be awesome and i generally don't use that word.

job one will simply to get turbo one evaluated of course given all the delays.

howard

 

Great news !
I only recently found that FP turbo (FP HTA GT3794R), sounds like a good combination.

Howard remind me again what dyno tuning are you going to do again to get the most out of all the results.
e.g. dyno at 14psi, dyno at 20, dyno at 30 ? etc sorry I'm sure you have noted this before but its big thread to re-read !!

 

the plan is to do 15, 20 and max.

my primary interest both from my engines and this project is obtaining the most real world mid-range on pump and AI w 500 being a max target. i am not looking to leave this earth.... just beat 99% of the cars i run against.

i may, or may not, be fuel limited near 600 (if lucky enough to get there). i need 600 (or thereabouts) to do the 200 mph figure in the standing mile. i have no interest in anything over 600 as i will only run pump and meth and my engine architecture is not designed for over 600.

since it takes 80 pounds per minute on a rotary for 600 neither of the first two turbos should cause a fuel problem.

emphasis is on HUTC (horsepower under the curve) as that is what wins races rather than just top tick hp. comparative turbo spool, exhaust back pressure, egts etc will all be measured on each turbo.

timing, and all the usual metrics will be laid out for all turbos.

while this all looks grand i will admit i am approaching monday in a reserved manner given the succession of weirdness that has occurred.

Awesome ! so looking forward to the results. Guess just have to sit back and wait now

(PS this is determing my new turbo purchase just wish I had you block :P)

 

Excited to see the results Howard. Good luck on Monday.

 

good luck!

 

thanks everyone, i appreciate your good wishes and do hope we get some data.

howard

 

looking forward to your results as I have a GT3574R and will be tuning for more boost this year, currently only at 12psi. Thanks for all the hard work.

 

In for some dyno results!!

 

we did over 25 runs today and i have alot of data to organize. expect it all laid out tomorrow.

the motor did 500 or more SAE from 6451 to 8520 at 24ish. of course we aren't thru w the BW but did learn lots which will be up tomorrow.

howard

 

Wish my posts were as educated as your's but for now all I have to say is I am happy to see things working out for you.

 

Oh mannnnnn this is going to be awesome.
