I’m puzzle???

Just to clarify. Both runs were done with 50/50 water/methanol. The 296 whp (blue) after installing the header and the 289 whp (red) before installing the header.

Also, the owner of the dyno was the one sitting inside the car when the dyno was done (dyno before installing the header). The guy got the car up to third gear and then he stumped on the throttle which was no to my liking but he told me that that’s the way he always does it.

On yesterdays dyno I was the one inside the car and I steadily pressed on the throttle once I got to third gear. You can notice that on both (blue) the power and torque graphs from 3500 to 5000 rpm.

The time graph clearly shows that the car achieved peak whp two seconds faster after installing the header. That might explain why I can spin my tires on first gear with the DSC on. In fact, I don’t notice ANY loss of power while taking off hard with the DSC on. This is why Bastage asked me if I disengage the DSC last week when we were messing around at a traffic light.

 

I’m spraying before and after the blower. 100 m/l nozzle before the blower and 60 m/l nozzle after the blower (just after the intercooler).

The car runs just fine in the 90~95 degree but the 50/50 methanol does start spraying as soon as I start driving aggressively. It is all controlled by the Snow electronic system included in the kit and based on the MAF voltage output.

 

I hit 283 rwhp without any w/m injection back in March. Granted it was in the mid/high 80's at the time, and Juan has hit 280's without W/M injection. It was just especially hot yesterday, and based on where he lives and where the dyno is, he had to drive through a significant amount of traffic to get there.

Pettit will optionally install the w/m injection kit with their supercharger.

 

Does Pettit do any special mods to the Snow Kit? I want one, but i'm not sure who to buy it from.

 

Order it thru Ray (BHR).

Here is what you need:

Snow Performance Stage II kit
Solenoid
T connector for dual nozzle
One 100 m/l nozzle and one 60 m/l nozzles
A case of Boost Juice unless you want to mix your own.

You can install it yourself with help from your old man and I be glad to send a boat load of pictures of my setup. You got my number too.

 

^ +1

That's where I just got mine from.

 

Yeah
Ray has the complete bundle needed.

 

That certainly makes things easy

 

water meth injection is a great idea for set up for a few reasons. now if you do some reading about this thing it may confuse you some. a dual nozzle set up is good for this setup for 5 reasons. Many other people do not like a dual nozzle set up but they do not have our kit.
1st- it can cool the temps within the blower(but no one has ever found high temps within the blower to be a problem)
2--once the water in the intercooler has reached a certain temp it can actually increase the temp of the air coming out it(because the w/m has the air cooled lower that it!)---so the second noozle
3- we have such long intake runners there are many many areas that heat soak the intakes before it reaches the ports.
4- the water meth will actually help a lot with carbon buildup.
5- detonation protection help (its not a guarantee)for a fi rotary engine is a must.

Do not forget to get an intake temp gauge

Hey Yall how many grams air/sec are yall seeing? at 7.5K i am seeing approx 294.
is that about what all others are getting?

Still kinda going through the motions unfortunately.
April 10th, break the heal and pull tendons loose on the bottom of the foot.
In a hard cast for two months. Then I get that off and wear the moon boot for one month. At least with the moon boot I can take it off and drive my car, so I've been doing that for the last month after renting auto's for two minths!
Went to the Dr's last Tuesday and he says....."okay, time to start walking on it, but only in tennis shoes and no hard athletic activity for the next two-three months". So.............. I get home(I have the moon boot off and in the car), I needed to grab something out of the house, so I leave the car running and hop(or try) to hop into the house. Foot catches the 6 inch threshold of the doorway and I go down really hard on the bad foot. Immediately collapse on the floor and writhe in pain for about 5 minutes screaming obscenities. Next two days are spend awake with no sleep and putting ice on it continually. After two more days, I call the doc and get back in there to insure I didn't bust it again. No break this time according to Xrays...........just a severe contusion of the Achilles tendon(insert your favorite obscenity here). Foot is every shade of the rainbow and swollen, so I have stayed off of it all weekend, and I think I've done no more than set myself back a week. Hard to tell with all the perciset(sp?) I'm taking, but I think that's it.
Oh...............as the car was running, I had to back it out of my parking space and pull into my one car garage using my right foot on the clutch and feathering it along with using just the handbrake! That was interesting................just took it real slow.

 

Damn I hope you heal soon I am dealing with an achiles heel injury now

 

Triple ouch!

Just wondering the assortment of drugs you are (were) taking the last few months. Yeah!

 

My understanding is this:
Water methanol is not a requirement for the Pettit kit, or any other boosted 8.
Most Pettit owners do not have the water methanol.
Any of the Pettit kits can make over 260 RWHP with a good exhaust. (mine made 296 catless)
There is debate on whether the water/methanol really does boost horsepower without tuning changes. (mine increases boost, I have not re-dyno'd yet)
The extra cooling of the blower seems to increase boost. (in my case to 10 PSI)
I have not heard of any blower or engine over heating from the Pettit kit with or without methanol.

With the temps in Phoenix, you should consider the BHR radiator, boosted or not boosted.

 

Rote8, you may want to dig a little deeper because at least one of the issues you cite has happened right in Pettit's own shop and that's why they are giving the BHR rad a try.

As for the other issues, Juan, Denny, Adam, and a few others are doing stellar work on fully exploiting the Pettit kit.

 

I have a track day at the homestead speed way next weekend I will data log all three sessions. I am thinking of doing one session with out meth just to see what the difference is.

 

What's the scoop?
Had not heard of any over heating due to the S/C.
The only issue I have ever had with over heat was due to an "upgraded" ignition system that the "igniter box" changed the dwell.
(Since removed and the car is happy again.)

PS: I am just Nitro'ing my Pettit kit.....

 

overheating not a problem for me at all--even on the track. i have only been talking about keeping the charge temps down--on the track the charge temps will go up a good bit and you will lose power IF you dont have the water meth.
what about my 294 at 7.5K grams/sec question? Is that about right for everyone?

It's not due to the supercharger, per se, rather the barely-adequate factory radiator. When ya go stuffing another 40-45% air in the engine something is gonna show itself underrated. As it relates to S/C owners I am only aware that Cam is unhappy with what he has found available, radiator-wise.

 

Thought that was RPM, not time.

 

So you overheated the motor because the dwell for the coils was insufficient ?
please elaborate .......

 

For sure...last time I checked the wrong dwell will overheat the coils.....not the motor??

 

Misfires and overly-retarded timing (both the result of incorrect dwell), will cause massive EGTs and that translates to overheating.

 

The misfires may not be the result of the dwell though. I have the proper dwell but I am still getting a lot of misfires.

 

so we have been sold a pup

 

Around 285 for me before my header installation. I'll try to take new readings by Saturday and will let you know.
