Two Jets; One Pre, One Post Compressor

!st Gear Pull, Two Jets. 50/50 Water/Meth



3rd Gear, Two Nozzles. 50/50


One Jet, Post Compressor

1st thru 4th gear, One Nozzle after the Compressor. 50/50 Water/Meth

 

You need to either convert it to text or make the images much larger. Looks like the middle dark blue is the AIT? Looks much lower on the 3rd gear run pre turbo.

 

I agree with Tweak. I can't see the graphs but atleast I can tell it's A+ stuff.

Is Manifold Pressure in absolute bar?

Those iats seem nice and low, but it looks like you are running 10psi ish...

 

Little confused on how on one, your temps are already in the 60s before you start the boost (1st gear pull), 100s the next one, then about 75 the next time. Getting the AITs the same before each test would help take out extra variables. Just an idea.

 

good idea. I'll try to take note next time, but I have no AIT gauge.

I added a crap load of comments along with these logs in Brian's thread.

ive been running 100% meth with nitro vp works great man. the intake is as cold as ice. the systom im using is cooling mist.

 

yes. I am running about 12 psi with a 9 lbs spring. I know you are running more boost, and that will certainly change things up a little. I am not willing to up the boost until I get the current system working flawlessly (or close too)

I would also like to get a S5 rear iron before I start making serious power.

 

Considering all of the possibilities, not a bad idea. Have you considered changing plug types? This was brought to my attention yesterday and it's something I'll be doing tomorrow. May want to yourself given where this experiment of yours, like mine, may wind up taking you.

B

 

are you talking about spark plugs? I experimented a little, but eventually went back to the multi-surface plugs.

 

Yep, spark plugs. I'm going to buy a pair of the GReddy Pro Rotary plugs for the Leadings; heat range 10.

B

 

in my limited testing, I've been happy with the 7s and 9s. I do have an MSD box and 10 mm wires tho. I may upgrade to blaster coils soon.

 

Definitely wanna ditch the 7's in the Lead's and atleast move up to 9's. The 7's will get too hot and cause misfires not too far from the power levels you're marching up towards.

You've got a T2, right? The factory ignition is very powerful. Also, I'm not sure on the MoTeC wiring here -- does it utilize the factory ignitors and coils?

B

 

yes, it all runs through the motec. I've heard lots of people say that the t2 coils are powerful, but I have a hard time believing 20 year old coils are better than blasters. I've seen side by side comparisons of the spark from blaster and stock coils... there is a HUGE visual difference.

I'll do some research on this, but I noticed a HUGE difference is ignition once I installed the MSD box.

I know a guy with an FD that just blew his motor running all 9's (I think). So I'll definitely have to research this more.

 

I gotcha. Ok. I know you're not doing a Haltech, but you may want to check this out if you are still using the Lead waste spark setup:

https://www.rx7club.com/haltech-forum-62/sequential-leading-ignition-haltech-e6k-e6x-811573/

If the MoTeC mimicks the stock ECU by using a 2nd ignition channel and 5V out toggle lead for the trailing igniter, you can copy that and do the same thing w/ the first ignition channel for the two lead plugs by replacing the leading waste spark setup (and dual-output coil) with another trailing ignitor and two coils.

B

 

wow, lots of great stuff there. It will take me some time to get through it all, but thanks for the research!

 

Here's the plugs I'm talkin' about, too. I think they've been mentioned in my thread; not sure about yours so here goes. I just ordered a pair of 10 heat range for my red car today from Ari at Rotary Performance.

It's pretty cool; elimination of Lead waste spark. And the real neato thing about it, assuming the MoTeC you use has control of dwell time and ignitor type, is you can use any kind of coil you want.

B

 

I have been making over 500 to the wheels and on 9s. if that guys motor blow, its becaues it wasnt tuned right or it was old and tired. i have been running 10s in my car and work great and there cheep. they cost me 2 dollers at the parts store. they are ngks and they are a regular plug. i was going to grab one at work and write the number down. i will put it up later for you guys.

 

ouch im still running 7s in leading, and brain keeps telling me to change them ha, ive been slacking!

 

Is it a snowmobile plug? BR10ES maybe?

 

i am unsure if the guy had 7s or 9s all around, All I know is he was running all the same plugs.... Maybe 7s. that makes a little more sense.

 

Hey B, do those plugs have a ground strap and need to be indexed, or are they multi-contact? I thought I read somewhere that they were just a re-labeled NGK racing plug?
