HI guys the red beast lives again!!
Just finished the installation and thought I would share some of the drama that has gone into making this work.
Final results
342rwkw and 7200rpm with 1042nm at 4000rpm
This is without any intake pipes installed and the throttle body vented to atmosphere.
With the air intake installed and the air mass sensor connected etc the power drops 43kw
It feels just amazing to drive with buckets of power at any speed the Michelins now have real trouble getting all the power down but as the power is so smooth you can make it bark or drive @5k's through a car park..
The initial design was to use a Richwood Technology kit with an intercooler, when the parts eventually turned up some 10 months after paying for the 2 kits (go figure) I was disappointed to find the intercooler was a joke and would never have worked. So that went back..
I then started to trial fit the parts and the issues are listed below. The blower would have hit the bonnet it missed out by 20mm The rear plenum failed to clear the rocker cover once the throttle body was installed. The intercooler was too small, it would also have supplied hotter air one side of the engine than the other.
So at this point we had major issues to rectify.
First to take some height reduction surgery was the manifold so this was machined down by 6mm not enough to get back the 20mm I was chasing then we took a look at the plate and machines the edge of this down so it sat inside the manifold by 4mm that gave us 10mm The blower kit came with a spacer kit to lift the blower 20mm from the top plate to allow enough room for the bypass valve in the rear plenum..
So off came 10mm from this plate that gave me the 20mm we needed. Next issue was the bypass valve no longer fitted; it fouled in about 4 places on the rear adaptor plate and the plenum.
Back to machining clearance sections into the plenum and adaptor plate..
Now we at least had clearance for the bonnet
Next step was to look at the injector fitment.
More problems!! The injectors were 10mm up the bore of the manifold and any spray pattern from the injectors would have hit the side of the bore and dribbled out in gobs of fuel.. Not conducive to lean running at low speed, economy etc etc. f….k me what’s next!!
Fix was to machine down the manifold where the injectors sit and also the boss for affixing the injector rail once done the injectors are about 2mm above the intake runner just enough for the spray pattern to be unimpeded.
Interesting to note is that the manifold from Bullet I am using for Steve Latimers kit is a straight bolt on with none of these issues...
It is lower, has un-impeded ports and just fits.. this would be my choice for any further fitments.
Next we turned our attention to the plenum from Richwood technology as we had lowered the blower and manifold the plenum would not fit and hit the rocker covers, so we cut the nose off the plenum and welded on a new one with the entry from the throttle body towards the top of the plenum instead of the bottom and cut the bottom off the plenum on an angle to clear the fuel rail. Ground it off and blasted it looks better than new..
This plenum is too small for serious HP and our new kits will feature a Yella Terra Plenum modified to suit our application, this plenum has 3 times the volume and flow capacity
To ensure the fuel stayed where it belongs I made steel fuel lines using the original banjo’s silver soldered at either ends.
The other major issue was the water bridge which fouled the blower, we also wanted to use a STD hose and get the top hose past the belt easier than the STD top outlet allowed.
I cut the original outlet off and welded on a curved section of aluminum tube that takes the outlet past the belt then ground off the rear of the bridge welded up the hole sandblasted the lot and all done.
From here on it was all plain sailing
Change the lower crank pulley for a smaller bolt on unit to keep the boost down to 15PSI
Fit the belts and on to the dyno.
Tuning the WOLF was a breeze and the thing that was mot apparent was the lack of induced heat from the blower, the M90 unit would get thermal runaway after just a few minutes and start pinging it’s brains out.. with the Whipple 7 hours on the Dyno no detonation and 20+ degrees of timing manifold intake temps after the blower of around 60c meant an easy to tune engine with great power.
The next step will be to add water meth, more timing and more boost, I am hopeful of getting close to 400KW + and maintaining drivability
I just screamed out "what!" when I read the 342rwkw and the 1043nm of torque! This is sooo good, my dream!
Good work Peter!
For some advice for me, what is the best area to start for this sort of power? If you don't mind me asking, the prices is upwards of 10+ grand isn't it?

Thanks guys it has been a long haul but the car feels great. You are right in that the Wolf does not need the AFM and does not use it. The factory AFM is there so the car has all the factory components installed, the blower is not illegal so long as all the factory metering is in place. That is also why the WOLF is hidden and the factory ECU is plugged in with a false loom.
You would have to pull half the car apart to find it.
It did cost me 40KW when I connected it back up but 300 for road use is fine by me.
You are right about the porting of the manifold it is not very accurate and the port are badly shielded by the casting, although I am not sure this would have any effect in a blown application, as 90% of the air exits the blower at an angle and blows hard against the front of the manifold then doubles back under itself.
I am working on a deflector plate for the blower that will straighten the air-flow so it exits @ 90 degree's or close to it.
I have a 6spd Getrag on the shelf for the car with a 3.2 T2 diff.. but thats a while off yet.
The price for the kit which will include everything to just bolt it on down to the last nut and bolt will probably be around $9000.00
All the kits will be trial fitted to a spare engine to ensure everything fits.
It will include a changeover Water Bridge and Changeover modified idle control valve.
Instructions for modifying the loom will be provided along with the wire to get the job done.
all in all the kit should take 10 hours to fit.
Power figures on a stock engine I should have next week once I have Steve Latimers finished.
His car is stock other than an exhaust, a set of Rush Headers and an SMT6 piggyback.

Wow that's good news Peter , hope I get close to those numbers also when tuned . We did it the hard way but it all came together in the end . I had my injectors set so i had 4mm from the open but i also did machine the manifold the same as the stock factory one with a grove cut into the manifold going back to the hole for the injectors so it would end up almost the same as yours .

Hi Guys there has been a lot of interest over the kit and I have decided to reproduce them in limited number as a bolt on kit. It will be supplied with the manifold, blower, injectors, injector rails, rear plenum, fuel pipes, bypass valve,idle air valve all assembled as one unit ready to fit, other components supplied are water bridge,lower crank pulley and new low ratio aluminum lower pulley, top radiator hose,idler bearings and bracket, wiring and fitting instructions.
some of these components are changeover and the injectors need to be supplied for this process to take place. To fit the kit should take less than 8 hours as most of the assembly has been done for you.
These pics show the manifold component of the kit fully assembled. (the throttle body is not part of the kit.) All future kits will get a larger volume rear plenum not the square one as pictured.
This kit on a stock engine with headers and exhaust should be good for 260rwkw and 800+ NM
When I have dyno tuned SL's car I will post the results
Thanks also to Neil Griffiths for all his help and advice on this project.

Hi Guys My engine is up 40 on the bores, low comp, has cams, big valves, ported etc. Rods are stock but it has ARP head/rod/main bolts/studs/nuts
I will have real figures (rather than a guess)for the kit on a stock 1UZ with headers and system later this week once I have Steves car finished.
300KW at the rear wheels with a stock engine with exhaust, headers, engine management( prefer to see a full ECU fitted as some piggy backs will not be up to the job) I have access to Wolf V500 straight plug in ECU's and I know Cihan has some other options that would work. should be possible or close to it. Certainly using water meth you would get there... I think :-)
The problem with all this stuff is that until you have done it you wont know.
Once I have a stock one dyno tuned at 10PSI I should have some idea as to how hard it can be pushed.. I can, using the current kit go all the way to 30PSI, so on paper huge figures are possible but in real life ????
One of the next jobs for mine is to increase boost to 20PSI from 12.8, then 25 and 30PSI and some careful runs on the rollers to see what happens.
I have a water meth kit fitted with a 250PSI pump but so far I have not used it, once the boost gets raised I will run the engine with and without the water meth to see the results. on Damians M90 Bullet kit I think we had 168kw without the water meth and just on 200 with it turned on.. Based on those results we should see @20 PSI with Water Meth around 450 to 500kw if I can keep the charge cool.

Hahaha Christian, i've just moved into a share house, budget has gone down massively. Even if i'm super tight I doubt i'd be able to save for this come the end of the year. So price depending of course. If it's 10k no way, hahahaha. 5 - 6k we'll see.

Hi Guys I now have some numbers for a stock engine utilising these components.
Extractors Exhaust system Wolf V500 ECU Supercharger Kit complete Water Methanol 250PSI injection kit Controller kit for water meth from Wolf V500
296RWKW and 800NM
Cost for the kit $11000.00
The kit is complete containing all the components above except the extractors and exhaust.
The kit just needs injectors fitting, anything around the 300cc mark will do I used early supra injectors in mine until I got over 350kw then I went to larger injectors. All fuel lines are made from bundy tube as per factory, other than the return line which is low pressure and routed in fuel injection rubber tube.
All hose clips, bolts and sundry items are supplied so it just bolts on.

Peter, the numbers on the stock engine looks great. Would like to know what is the size of stock injectors? What is the maximum injector size does the stock fuel lines take, above which we have to upgrade the fuel lines and the fuel pump?
Also Peter, any idea what numbers could be achieved with out the water meth system? Thanks
