If all goes well Saturday I will get some Baseline numbers on the following Set-up:

NEW Pineapple Engine
Stock ECU
Stock Intake
Deleted Rats nest
Pineapple Sleeves
Stock , with gutted cats, exhaust


After we obtain those numbers the Microtech LTX-8 will be installed and tuned, then in the future a return visit to the SAME dyno will occur.

After that, the RB Road RAce Header and UBER NICE Collector and exhaust will be tested.


I hope this Staged testing of mods will give me a better idea of the mods potentials.

Stay tuned!!!

 

GL with the LTX install!

Tip: For the pink switched ign, use the tan wire on the stock ign harness (trailing).

 

I wish I had a beater that I could afford a computer system for. Good luck.

Looking forward to it. Just one question: What year car?

 

Started life as a 86 BASE Automatic. Now has a Pineapple Racing Miata Geared 4 speed.

It appears that the 6 ports are not opening/operating properly. Think is a DOG to REV.

Another Problem is the 3.9 Non-LSD rear-end.

Will troubleshoot the 6-ports sunday. Since I am installing the LTX-8 soon I will go ahead and wire the RPM switch up with an Electric Airpump to actuate the 6-ports. Updates to follow. A very frustrated Banzai

 

Just wire thoose suckers open and get a baseline, and use that for both, you just lose a little below 4k, but you should lose the same on both.

 

The 6 ports weren't opening today. So I ran around with them wired open. Unfortunately, it will not idle with the AC on and the ports open. Stopped by the parts house and picked up a air horn compressor. Will install that with a MSD RPM switch to Activate a solenoid to control flow.

 

Yo,


Banzai, I feel you man. It was the same when I dyno'ed for the first time. 140?! What?!

Surely there must be some mistake...

Nope.

Oh well, I'll have to re-dyno with all my new shizzattie on there.

Good luck and fingers crossed for next time!

the only problem with the air compressor is it does not open the 6-port gradually. This is what I have on my car right now.

 

Be sure to use a Relay. Even up 'til today, I have no problems with my fully blown electric auxilliary port setup.

 

I'll support what silverrotor said... No problems with the full-electric setup.

 

I'm gonna avoid the sleeves in my rebuild. Engine builder is going to insert piece of teflon into aux. port all the way to end of it. Will then port the transition smooth into the chamber. Port match the lower intake and eventually we'll dyno it. He's about ready to set up a website and start selling engines on a larger scale. My car will be the example of what he can do with a 6-port engine.

 

Ive seen 118rwhp and 116rw tq on a completely stock s4 N/A 5-speed. You really need to get those ports working.. and the 3.9 probably isnt helping the tq numbers. Are you still using an auto (confused about what you said about using miata gears, but still a 4-speed?)

 

Update on the dyno Banzai?? You get the ports to open?

 

nope 5 Speed miata geared S5 manual tranny. Changing the rear-end and 4 lug suspension out tonight.

6 ports: Right now I am running around with them wired open, not really pleased with that option. I am waiting on RPM modules for the MSD switch to get here.

Dyno run again in 2 weeks, I have to drive 3 hours to get to the dyno.

 

what type of numbers are you expecting this next run?

 

Not really sure on what I expect; I would be satisfied with 160 at the rear wheels. That is a stretch though on the stock ECU. I will have a wideband testport in the exhaust so I can extract some usable data. I may just say to hell with testing on the stock ECU and go ahead and install the Microtech.

 

NO! I really want to see how much of a gain with just switching over to a microtech..

 

I am open to contributions to do further dyno testing.

 

haha, how much does it cost you? Not including gas money

 

120 and hour, plus 3 hours each way...

I want to do a COMPREHENSIVE set of tests
Series one:
1. Max Stock ECU/semi-stock exhaust with stock intake & working six ports
2. A run with the 6 ports shut
3. A run with the 6 ports wired open
4. Remove Stock intake box and install Cone Filter.

Series II:
1. RB Road Race Header and "Banzai" Collector
2. RB Road Race Header and Burns Custom Collector
3. SDJ Motorsports header

Series II will be the Microtech Install and tuning runs

 

update banzai?

 

His Pineapple motor took a dump. Probably be awhile now...

That seems to be a becomingly common problem these days..

 

Yep, need to pull engine, but I am swamped at work and I leave for a well-deserved cruise to the bahamas next week!!
