Progress Thread Project Silver Fox - 3rd time’s a charm

[96pushrod]

I'm running 2 and I'm trying to remember... I think i have a 10 under the blower and 2.5 or a 5 before the blower. I'm drawing a blank for some reason today

Probably close enough lol.

I ordered a pair of the aem 1000cc ones(they come with 3 different pintles to adjust: 250,500,1000), which is essentially 15gph.

I’ll probably just end up running one of them for now. I’ve got a big intercooler so I’m not really looking for air temp change, just extra octane rating. Static compression is around 10.9 so I want to keep it happy.

Ya I'm doing both cooling and octane boost. I have no intercooler. I can still get some toasty intake temps at low boost. I have mine coming in around 3-4lbs and can see the temps drop dramatically the longer i stay in it. Steve also set up my ms to pull timing as temps went up. You'll also get richer once the menthol starts spraying.

No intercooler seems like where meth would really shine.

Got the nozzle taken care of. Picked up a friend’s old meth tank and pump. Tested them out and it worked great. Aem nozzles came in, really like the design with the serviceable filter and easy to change pintles. Just sucks they’re almost transparent, makes them tough to tell apart. The snow nozzle bung that go in the silicone coupler are pretty nifty too. I loctited the capture nut in, even though there’s virtually no way it could fall, since the nozzle would have to come out too.

My scale from Amazon came in today. I’ll get a couple bottles and mix up some 50/50 water/meth.

Tank is mounted in the trunk, didn’t take a picture of it since I need to loom up the wiring still. Running the pump triggered off nitrous 2 out in the megasquirt, going to arm the pump whenever it goes above 107kpa.

Unfortunately the solenoid didn’t make it to the house today, but god willing it should be here tomorrow. That will be controlled with pwm via nitrous 1 output.

In one of the pictures you can see the new magnafuel fpr. I had the larger version of that on the car, but it wouldn’t rise in fuel pressure with boost. Would drop pressure under vacuum, but wouldn’t rise. I caught it on the datalog, so I replaced it. I’ll end up rebuilding the old one when I can get the rebuild kit.

Solenoid came in today, it’s a cute little thing lol.

Wired it in and tested it, was all good. Seems like 26hz is the frequency it likes. Gonna get the wires all loomed up and do a little testing to see how much fluid actually comes out with different duty cycles.

Was definitely time for a fuel filter element change

I’m really surprised how much smaller the summit brand filter is than the aeromotive one. I guess I thought they might have been made by the same company, but they’re not.

I’ve got an actual pair of aeromotive filters going in, but of course I’m shy one -10 orb fitting. Guess it’s the only one I don’t have. I’ll see if any friends have one if not I’ll have to hit a local speed shop tomorrow morning.

Got back from Florida looking at some houses today. Might move down there in the coming months.

Got home and figured I’d put a smaller pulley on the blower.

 

[96pushrod]

Made a couple short pulls with the water meth. Seems like about 2.5* extra is where it likes to be. Spraying 1000ml at 100% duty cycle once it sees around 7lbs of boost. 50/50 water/meth. Looking at the strap I’m sure it could use another 1.5 or so, but I’m going to leave it as is.

Little black spot on the porcelain is a piece of dirt.

Did a pull with a friend on the water/meth. Ran 127mph with the two of us in the car, right about 3350lbs. Leaving super soft with a 2.23 60ft. Pulls nice on 10lbs. Gonna pulley it for 14psi when I dyno it next week or the week after.

 

[96pushrod]

So I was doing some thinking about a safety for the water meth setup, in case the pump or solenoid decide to the bed. I believe this will be the simplest plan: A pressure safety switch inline from the noid to the nozzle. I actually had this fuel pressure switch I never used on an old nitrous setup, and I think it will be perfect.

I’ll go to the local hydraulic supply tomorrow and grab a 1/8 npt tee.

Then I’ll ground one wire and attach the other to the “table switch” wire on the megasquirt. When the w/m pump is armed, and the solenoid is active the pressure switch will provide ground to the table switch wire on the ms. I’ll setup a second ve table (which will actually be less fuel than the first to compensate for the added meth) and a second ignition table (which will add 3* of ignition advance, or more) to be used only when positive pressure is in the line to the nozzle.

Should work

 

[96pushrod]

Got the safety switch. Made sure it does what it’s supposed to when there’s meth going through the nozzle and it works well. Did up a second timing and ve table.

Put an indicator on the digital dash that will light up and say “meth” when it’s on lol.

 

[96pushrod]

So I tested out the water/meth indicator, worked perfectly. Lights up red when there’s pressure on the nozzle and it’s in the alternate ve/timing tables.

Got caught in the rain the other day and the car died. Sucked up enough water in the filter to effectively clog it. Had to vacuum out a little tiny bit of water from the intercooler today lol. All good though.

That dash alone makes me want to convert to megasquirt

The dash is awesome. It can display pretty much anything you can think of. The gps speedo is nice too since I can put any tire size on and it’ll read correct.

Scaled the car today. 3072lbs with no driver in it. She heavy , gained 100lbs from the blower install and with the nitrous removed.

That's not bad really. My 87 coupe weighed exactly 3000# and it was a manual window/lock car.

If I could just get it back to the weight it was when the nitrous was on it I’d be pretty happy. Considering the car has zero weight removed besides no ac or power steering I think if I really wanted to I could get 100lbs out of it.

 

[96pushrod]

Alright so this will be the final pulley change for a little while

Went from 54 to 52 and now 50. I hope this will make about 13-14lbs at 6500 engine rpm and should really wake the f1r up even more. Any more blower speed and I’ll probably need to add a second meth nozzle, which I actually have lol.

 

[96pushrod]

Got dyno time scheduled for august 29th. Looking forward to seeing what it makes. Did a little pull in second gear this morning and it made about 13lbs of boost at 6500rpm which is right where I want it.


Been working with a friend to do HCI on his 87 vert, as well as un-uglying (that a word? Lol) his engine. I did a v2 install on it a couple months back.

Very nice!
