Step 1. Hardest part, locate blower and filter


Step 2. Disconnect pipe from blower and filter using a flat head screwdriver


Step 3. Pull out restrictor plate



Step 4. Put pipe back on with filter connected.



Restrictor plate close up. Measuring tape shows it went from a 2 3/4" to 4". Hopefully I can hit 12psi??? instead of 8 psi now. Now that should equate to more than 50hp but I'm going full retard and lowering the VE table for the addition of a 50/50 mix of meth. My last run with no meth I went like this

WOT

50mph to 112mph
Peak boost @ 7.8 psi (2nd gear 5,690 @ 68mph)
Timing 12* down to 9*
Max rpm of 6418 @ 81 mph (only shift during run, 2nd to 3rd)
IAT 72* to 126*
7.0x seconds

I drove around with my restrictor plate in for awhile and decided to take it out and it felt much stronger without it... I see almost 12psi with a 4.38 pulley on my d1sc without the plate and was seeing 8psi with it installed so I'm thinking you will have similar results... I do have a 4" inlet as opposed to the plastic dongle though

About time you quit FKN around with that thing and let it eat.. Hit it with meth and let er go!

That's a 9.90 car right there...

danieloneil01

I'll be making it's first hit tomorrow morning, 0330am on my go to back road.

ajrothm

Make sure to log it. Also make sure to purge the meth line from the pump to the nozzles with the "test" button before you make the first hard hit.. I do this every time before a hit to make sure the meth is working and primed up.

I made a hit on mine at 4:45 am this morning on the way home from work on 45.. LOL

Probably do it again tomorrow morning on the way home.. No traffic = zoom zoom.

danieloneil01

Woke up late this morning and will try in the morning. I always log when I drive the car unfortunately. I'm also to scared to zoom zoom on the highway. I always think there's a cop watching. If the AFR is in the mid 10 range then I'll leave the VE table alone. I have a #5 and #10 nozzles but right now I have the #10 in. I tried the 5 a while back but it wasn't enough to keep the temps down.

ajrothm

If your AFR is in the mid 10s without meth, its gonna go pig rich on a #10 nozzle.. You're gonna have to pull some fuel out of the map..

Ideally you want it at 10.8-11.0 AFR ON meth.. Any richer then that and it's just killing power, and not likely any safer. Only benefit to having it richer then that is if you have a meth system problem, more fuel from injectors gives you room for error..

Mine is VERY meth dependent.. I'm around 10.6-11.0 AFR on meth in 3rd gear (1:1). Its a little leaner in 1st/2nd gear so...I don't really want to lean it out much more.

The difference from 10.5 AFR to 11.2 AFR is about +40hp (@11.2).. Not to mention the engine is less responsive when its pig rich.

You need to hammer on that sh*t, don't be scurred.. I made a hit on 45 today right in your neck of the woods at lunch time. LOL. 60-120 happens pretty quick tho.

does the new style a&a kit have this restrictor plate

a/c man

No its a ECS thing pretty cool though

danieloneil01

Without meth its running 11.4 to 11.7 and this is only in second and a little in third gear. No idea about first or fourth. Injector duty so far has peaked at 70%. Do you only pull timing if the meth fails?

240Z28

Why does ECS have this 'governer' plate in their kits? Is it to limit output for stock engines, and built engine owners are allowed to not install it?

ajrothm

Yes I pull timing based on IAT. I start pulling at 120*.. At 140* it pulls like 10*.. At 150* it pulls like 15*.

You really want to do your tuning in 3rd gear (1:1). I have found though that 1st gear will be a leaner then 2nd, and 2nd is slightly leaner then 3rd, at least at the beginning of 2nd.. Not sure why this is but, I saw it with the stick tranny too.

Your AFR without meth is perfect!

Also I wouldn't let it shift to 4th at wot. 4th is highway cruise only, not for power.

danieloneil01

Well my car doesnt like anything above 12* timing or my knock sensors are to sensitive. Above 1.20g I got 0.5* KR and just below that I got 2* KR. The KR started right before I went WOT.

Meth on full tilt with #10 nozzle 50/50 mix

6100 shift point and it shifted to 3rd right below 6400
59 mph to 115mph
11.3 to 10.5 AFR
11 to 12.5* timing
73 to 90* IAT
Started at 7 psi and ended the run at 7.5 psi
6.4 seconds


Peak Boost
6,000 rpm
11.5* timing
11.1 psi
11.3 AFR
79* IAT
85% IDC

Dang and I thought I was going to find out something I didn't already know!

Thanks,Matt

DOUG @ ECS

Switch to straight meth!

ajrothm

Get rid of the 50/50 BS... Get true VP M1 methonal. Get it at Hops propane on Hwy 6 in Santa Fe, they keep it in stock, I buy 5 gals at a time.

Still seems odd you are getting KR at 11 psi with the AFR that rich and meth/water, especially with that low of an IAT...

I'm not recommending you do anything with the knock sensors but, I know you can program their sensitivity and the decay rate.. I'm not sure what mine are set on..I'd have to look when I'm home.

danieloneil01

But I got 8 gals of 50/50. I think im going to make a hit on my backroad with 13* timing and pull a plug. If it looks good I'll get with someone to see about lowering the sensitivity just a tad.


Doug, ever had to do that on these cars before?

FourG63 97GST

why is it their in the first place

danieloneil01

Because 8 to 11 psi is a huge difference on a stock engine.

danieloneil01

How long should one be able to stay at or close to max boost? It seems without the restrictor plate I only get 11 psi for a second then most of the run it's around 8 psi. Should you stay at 11 psi once you reach it until you shift?
