S.M.C vs. alkycontrol

[salvageV6]

Youse guys are funny all 3 of ya.

Don't forget to pull your pants up when you're all done wankin'.

Didn't need heads and cam. to run well with alky. on a fullweight car. That would be 3800 lbs. with driver.

Klotz lube is recommended for methanol injection too John, you might want to try it. Not scammer at all when you put it in the tank, prolly could use it as lube when you are crossthreading those filters on your car.

Methanol is nasty, cheap but nasty, lube it up to protect those internals.

Sorry if it takes you guys 3 seconds to go from 10 to 28psi. boost, my car is a bit faster there so no need for a progressive controller.

Okay back to your regularly scheduled informercial.

Peeling paint, oh my if that's the best you can do.....

Evolution is good, prolly better off with a GTQ turbo however.

Wish there was a DIY answer for this poll.

Well at least I find y'all entertaining.

Why would someone buy a huge GTQ turbo to run 12's

 

[19gn87]

Possibly one who is swayed by marketing??

 

[salvageV6]

Just shows what youse guys don't know.

There's little GTQ's for sale too.

The PTE51 might be called a GTQ variant as well since it has the GT wheel in it. It ain't too big mine works great on the GN.

Lots of ways to go "relatively" fast.

If there is enough interest in the DIY option, it wouldn't be too hard to come up with a design for a PWM motor speed controller with pump voltage based on boost pressure. The only problem is coming up with the time to do it.

1st of all view the polls, 2nd ITs Razors(alkycontrol) for me, I had a SMC-lost a motor due to pump failure. I now have the Alkycontrol Progressive kit & the way it works, quality of components, & reliabilty is awesome-Most of all is Julio's sincere & knowledgeable support!!!

Well unless Razors system has something that cuts the spark, I don't see how his settup would protect you from a pump failure either. What would be the best way to set up an alky system to protect from pump failure? I know he uses a supposedly superior pump, but in my experience all pumps fail eventually. Hmmm. This might me the next upgrade on the system. Congrats to Razor on a good product with a very loyal following.

Yup.. three months of subjecting my car to R&D , 8 different variants of the same thing, making the PC Boards, adding regulation, surge suppression, filtering, testing, wiring, etc.. all for under 200.00. "IF" the product existed when I needed it, I wouldnt be here today.

And if you search.. the PAC was designed with the DIY in mind. Hence why my site the items are available individually. Then the kits came as a demand issue.

As of 4-14-04 not one PAC controller sold has failed.

Any ideas how to cut spark and not toast the motor at high boost? If you look at the thread "Need ideas on a new product" I've started playing with a flow sensor to ultimately address this question. Tho havent found a simple way to shut down the motor in case of low/no alky output. Maybe have a 30 amp relay wired into the coilpack/distributor main power wire.. if boost=X and flow doesnt equal Y.. trip the relay and cut power off to the distributor.

Only ideas

FWIW, as of 4-14-04.. none of the pumps i've sold have failed

Thanks for the thumbs up

I wouldn't cut spark without cutting the fuel and alky too.... Otherwise when it re-lights you might blow the mufflers right off the car.

as of 7/02 my smc pump has not failed

Thanks "B"

Any ideas on an engine shutdown? That would be safe

 

[TurboBob]

shut the power off the the ECM........

The question is how to re-enable it. I would keep it off until the throttle is closed.....

B

 

[Razor]

Always concerned about it relearning. How bout killing ignition power until TPS goes under a 1 volt. And a small delay. I'm just trying to avoid kaboom from the ecm relearning when systems go back on line. If the ignition is put back on, and the motor is still spinning.. it will run.

 

[TurboBob]

If the ECM is still delivering fuel, the engine will pump it into the exhaust system and mufflers. If it re-lights, kaboom.

The ECM won't forget, it will still have power thru the orange wire.......

The ignition power fuse feeds the ECM too. blow a fuse and solder a wire to each blade. Use it for the CCCI/ECM fuse (I think) with a relay and fuse in series....

Trip the relay under a fault condition, reset it when TPS < 1 volt.

[Razor]

Similar to cutting the ignition off until TPS< a volt.. then relatching.

Get rite on it

 

[TurboBob]

yes, cut "Ignition Switch" power off from the ECM, so it doesn't put fuel into the engine.....

Let me know how it turns out....

Julio,

AKA Razor,

I like the idea of a way to shut down if alky flow is interupted.

I've been toying with using two pressure sensors in the alky line:
If the pressure falls too low (pump failure - no alky in tank-etc) or too high (clogged nozzle) I would like too remove all performance adders used only with good alky flow.

I'v obtained a Spark Translator which will adjust the timing with a voltage applied (the brown wire) & a Boost Controller (shut off 12v to it & revert to wastgate spring pressure).

My question is: Will these two units react fast enough to prevent engine damage?

TIA

I dont know. As you know things can happen really fast in one of these cars.. At best yes it will. At worse.. it may minimize damage.

I was going to do something with MAP sensor voltage as a threshold for triggering the device. Then using a pressure switch set to 80 PSI... if the map sensor voltage goes to 20 PSI boost approx 4 vdc, and the pressure switch is closed everything normal. If the voltage goes to 4 vdc, and the switch is open due to lack of pressure, kill the ignition fuse.. until TPS is less than 1 vdc.. at that time reset. And obviously fire a warning when the breach occurs. This warning can be connected to any other systems within the vehicle.

But this has the limitations of flow not being known. But should be relatively inexpensive.. as the positive.

Dont know bout it being too high.. hi pressure isnt the issue, unless your system is a fixed output one, even still the final output may never reach the pressure switch even with a clogged nozzle. Example would be a weak pump. Clog the nozzle on a weak pump, it wouldnt ... you get the idea

I'm more in line with my car needs "X" amount of pressure at "Y" amount of boost as a minimum. I run a filter so a clogged nozzle wont be an issue. Set the parameters to meet the condition.. there's the fail safe.

Am I off?

 

[smokinttype]

Razor, I am considering one of your kits but I would like to know YOUR mods espicially your injector size, timing and whos chip your running. Thank you

 

[Razor]

Mods are as follows as of 3/04.

Ported heads, 210/205 cam, walbro307, pt51 w/.63 housing, protorque 2800 converter, roller rockers, stock pistons, crank, rotating assembly, ported intake, RJC plate, 58mm TB, stock IC with no mods, stock GM rear and front suspension, 160 stat, built tranny, THDP w/HD actuator, MSD 50's, engine tiedown, stock exhuast w/DMH cutout... thats it.

Chips i've been toying with as of late are from Bob Bailey for the translator/extender, and from Eric Marshall(turbotweak) with the stock MAF. Both work well.. I havent had time to sort what the car likes best.

It ran 98.4 mph in the 1/8 with Erics chip, and it ran 11.40 in the 1/4 with Bobs chip.. i'm sorting the car after the heads and cam.. havent had time to play with it Timing on Erics was a 23-20 program. On Bobs was a 23-21 program. I like them both. A month ago ran 120.7 using a thrasher 93... I think it will run 124-126 when its finally sorted. And these runs were on drag radials.. hence the 1.7 60 foots. I need to really launch the car.

No majic..
