Thanks. And yea, looking at the tune it makes sense since the ECU pulls timing as IAT goes up.

Ordered the Snow stg2 MAF kit. Thought about going with aquamist but at less than half the price, I figured I'd start with snow and go from there.
 
Doesn't need to be fancy, just needs to get water inside the engine. Good call on pulling the trigger.

The setup I had was a single nozzle Snow boost referenced kit. Eventually turned into a dual then triple nozzle.

Look forward to seeing your review.

Pete, why aren't you putting the PWSC on that thing? Bigger blower with charge cooling, AND you can spray it too!
Baby steps...I managed to rip off the front lower control arm mounts under heavy braking and hard cornering as it is. Frame is getting re-welded and reinforced. But even the extra ~40whp made it much more of a handful. Plus I'm still running the stock motor - my old built one is on a stand - waiting for me to grow a pair.
 
PWSC adds complication and even more discontinued maintenance items to an already odd build.

Plus with all the extra stuff it adds even more weight. With the water meth injection it'll cool just as well as the charge air cooler on the PWSC without the added cost, weight and complication.

Smaller pulley, more w/m and call it good(if you want more power).

I actually like the PWSC design quite a bit. It needs some improvements (i.e. better water pump / fittings / lines) but it's very solid plus the install is a total breeze on the kit car. Can't really make 200whp with the M45 on a stock compression zetec without some crazy RPMs on the rotors which isn't really something I want to do on the track.

That being said, I think I'll milk the JRSC for another half season or so.
 
I was under the impression this was an M62.

All of your photos show it to be a M62, same as a PWSC.

I agree with your points if it's an M45. But i've never seen an M45 look like that. Also your IAT's not going above 160 degrees during a track session is impressive if it's a baby JRSC.

What boost level were your numbers made at?

Edit; your power numbers make zero sense if your using an M45, those are just a hair below a standard BBK M45 numbers and a BBK spinning M45 would never stay under 160 degrees during a full track session. Has to be a standard pulley on a 62 to stay that cool. And your numbers are almost dead on fully stock Zetec with a low boost M62 on the back of it.

Most definitely an M45 with a stock pulley. Pushing 5psi at the peak. I had the PWSC laying next to it and the JRSC looks like a little baby compared to it.

Note that even though it's a stock motor, I do have the cams adjusted slightly to work out a bit of the overlap out.

Note that how this whole thing started with no boost, I then had the blower rebuilt by Stiegemeier and I had them do their stage 7 magic on it while it was out there as well as a port and polish on the manifold. They were advertising ~30degree IAT drop from it - looks like they weren't lying.

And to pimp their stuff just a bit further, this is what it looked like when it came back:



Of course you get what you pay for and between the rebuild, stage 7, port work and paint, it was on the pricey side - about as much as what you'd pay for a used kit. That being said, I think you kind of have to expect it.
 
You know what, I wasn't really thinking about the rebuild and port work. Those numbers make sense just purely because that thing is much more efficient now, and it's not building much heat at 5psi.

Standard M45 would have trouble coughing up 160whp on less than 7-8psi.

SM really does good work, charger looks nice. Did you have them port the manifold as well or did you just send it so it could be coated at the same time?

I had them port the manifold as well. It wasn't that much extra and at that point I figured might as well make the best of it being out there.

Depending on what I end up doing, I might send the PWSC to them for the same treatment - maybe minus the manifold porting since I hear the PWSC is tuned pretty well in that aspect.

As far as WMI, the kit came in yesterday and I'm going to be getting ready for install. I think I'm going to cut off one of the pre-rotor vacuum ports and tap the hole for the nozzle. I'll most likely start spraying just water to protect the rotor coating (which is brand spanking new from SM). I have AFR tuned pretty well now so I don't need to be dumping a ton of methanol in there making it richer still - backfires quite a bit as it is.
 
Can always inject in the manifold if you're concerned about rotor coating.

I've never seen the coating make a large difference in boost production. .2-.4psi in my experience(going from full coated to zero coating on my m45).

I always liked a heavier water mixture in my car, but it definitely did like some meth in the mix. I think one of favorite mixes was 1 gallon winter mix cut in half with a gallon of distilled water, so 75 water/25 meth...ish. It was close enough and made the bottles last.

Also, fwiw, you'll lose the same amount of coating basically with anything ran past the rotors.

PCV still going through the top? That oil will eat the teflon. Straight water will, straight meth will...either or, or all of the above will.

I wouldn't worry too much about it honestly.

Definitely considered going into the manifold, but the JRSC manifold is tiny and I can't see how the mixture would get properly distributed to all 4 cylinders with the one nozzle that close to the head.

On something like the PWSC I'd be way less concerned since the're quite a path through the manifold.

Also, I hear that on the M45 there's a cooling benefit on the rotors in terms of compressor efficiency and sealing particularly on the baby sized blower.

PCV is going to a catch can (so is the valve cover breather). EGR is eliminated. I'm currently not using any of the pre-rotor vacuum ports and have the FPR connected to the manifold as well as a boost gauge. IAT is connected to where the brake booster normally goes (bottom of the manifold).
 
When I did 3 nozzles on my WMI, I did my largest pre-rotors and 2 in the manifold, 1 in between each pair of cylinders 1/2 and 3/4, each was mounted in the center of each pair. Worked well with the smallest nozzles available.

But yes, I agree, Pre rotors is absolutely the best solution, was just offering as an alternative should you not want to wear the teflon.

Definitely, I appreciate all the advice. Spoke with SM about it as well and they pretty much summarized the same thing...coating will wear off no matter what, methanol slightly accelerates it. I'll start with water and if I see any issues move on to a mix.

Still waiting on the car to be back from the shop - the last track weekend took a bit of a toll...

Good eye, that is a Sierra rack.
 
You are a wild man! What is the material and thickness on that frame?

Finally got the car completely buttoned up and back on its tires, and now the battery is bad. Haven't been very motivated with the weather here, hope to have some data logs to you before too long.
