Dont forget about those cylinder walls floating around if you've got too
much boost in there. I'd hate too see this much quality work go down the
drain.

When are we going to see some pics of all this stuff rod?

Rods turbo setup

Post by Rod Grosvenor »

The tech I`m working with has a 3.8 turbo Grand National running the stock
factory cast 8.5-1 pistons & 23 psi boost with the alcohol injection; it
flat gets into the wind! There are many open-deck Subies running insane
boost with virtually no problems, but I understand your concern. Part of
doing this NA motor in this fashion is to find out what works & what
does`nt. This info will be applied to the new motor which will have 9.0-9.5
to 1 forged pistons, relocated top ring, ceramic coated piston tops,
ceramic-coated combustion chambers, reworked crank, HD rods, fortified block
(after extrude honing & a process that solidifys the block material; have`nt
decided on temperature or sound process yet-more research is needed.) Along
with special cam timing, headwork, intake manifold work & throttle body, Nos
will be added for 3rd & 4th gears only. This allows reasonably sized ports &
flow characteristics for low & mid-range torque while maximizing the top end
with an additional boot-in-the-butt. If I lose a head gasket in the near
future, your suspicions will be confirmed. If not, I`ll continue to play &
kick major ass whenever the mood strikes. And yes, if a current WRX has`nt
had any major upgrades, I have no problem at all with them. A recent Acura
RSX also knows the "Wrath of old Legacy." I have`nt had this much fun since
I discovered pull tops on beer cans. I`ll have some pictures within 2-3
weeks & I`ll scan them in for all to see. Bye for now---ROD (AZ.)

Rods turbo setup

Post by Matthew Reese »

Rod,

I have a North American Turbo Legacy '91, and I am trying to kill detonation with water/alcohol injection. I am curently using a nozzle with a flow rate of 150ml/min. Pump is rated at 18psi. Injecting right bfore throttle body. System turns on at 3psi. Every time I test it, the detontation disappears but my performance drops. I must then reset my ECU and performance returns but so does detonation... How many ml/min should I run?

Mods - MBC at 15psi, 2.25" exhaust with no cats and a high flow muffler, K&N with cold air intake, deadened the knock sensor signal to reduce timing retard

Car is an auto and running really quick at an ave of 6.7 0-60mph


Any ideas?

Rods turbo setup

Post by Rod Grosvenor »

Hello-A couple of suggestions: eliminate the water mix with your alcohol (denatured I presume)-you need a boost timing master to retard the spark properly as it sounds like a problem in that area. I can only run 12 psi for now until a finer spray nozzle comes in & timing is retarded in conjunction with boost increase. The pump & nozzle volume seem ok but I`ll have to wait until my dyno run to confirm. You should`nt have to reset the ECU as I travel to the dyno shop (at approx. 1300 ft. elevation) back home to over 5000 ft with only a slight decrease in alcohol for all to work properly. Obviously, this is due to less boost being made at higher elevations. Keep in mind that I`m running 9.5-1 compression with far fewer detonation problems than you. BTW, who`s alcohol kit are you running? Are you running a QUALITY premium fuel? (I know this sounds like a stupid question, but I had to ask.) I use an MSD DIS-2, part #6212 that has a programmable retard feature; this is the only CD ignition out there AFAIK that works with our ignition system & will give you the ignition control you need. Let me know your thoughts...---ROD (AZ.)

try turning down your boost. If you don't like that, then get an
intercooler.
