Wolf Creek Racing - Mikuni 40's

[Travel'n Man]

Just arrived from Wolf Creek Racing

Todd has done a fantastic job with this new addition to my car. I'm really stoked about getting these on and the car fired up. All soda blasted and ready to set the idle and sync. Pretty close to a plug and play install.

I'll be removing the current mechanical fuel pump and adding an electric one along with a pressure regulator to maintain fuel pressure at 3 +/- .5 PSI along with a heat shield and triple fuel rail.

The jetting setup is:

40mm Mikuni Carbs

32mm Venturis

40 Pump Jets

57.7 Pilot Jets

150 Main Fuel Jets

190 Air Connector Jets

Hometown elevation is 3200 feet

Hope to install over the weekend - stay tuned for further updates.

Wow! That is a PRETTY set-up!

No doubt! That is drop dead $exy. And emphasis on the $

Very nice setup indeed. Is the heat shield and triple fuel rail also sourced from Wolf Creek ? What is the pricing level on the shield/rail if i may impolitely ask ?

Mike -

Todd at Wolf Creek Racing could not get the heat shield or the fuel rail. I had to hook up with a guy from Japan to buy and ship it to me. There is a source for the heat shield but I could not find the 3 barb fuel rail anywhere in the states at all.

Heat Shield was a breeze to attach - very supportive and raised edge all the way around to add support to the vibration and heat. I am adding a heat barrier to the underside that reflects heat up to 2000 degree at 90% - gotta keep the fuel cool!

Beautiful!!!

Those are sweet! Any guess on what kind of horsepower increase they will add?

Rich -

From my understanding talking to Todd at Wolf Racing and Dave at Rebello's they should generate around 40 additional horsepower - my engine output should be close to 270 horsepower with the engine rebuild from last year and the head work from Rebello's. I could have pulled some more horsepower out of it but really no need since my intentions are not to track this car. A different intake manifold would have gotten my closer to 300hp. At some point I will dyno it but just so my plugs are looking good once I get the install done I'm really happy where I am currently. Next years project will be a 5 speed / r200 / upgraded half shafts.

Hopefully to have this finished up over the weekend - it should just take a couple of hours to get everything hooked up and sync'd.

Very nice. My bet is that you won't be able to keep your foot out of it.

Hopefully install will be finalized tomorrow evening - stay tuned for pictures............... Ended up using a Lokar Throttle Kit that is really much superior to the current linkage. The intake manifold ended up being pretty short and does not give much room to complete the install due to barely having enough room to bolt the intake on. Removed the current bolts and replace with shortened studs. Fuel pump mounted good - inertia switch with relay - fuel pressure regulator. Pressurized the system this evening and fuel lines leaked using the original Datsun fuel clamps. Moving to EFI clamps and may have to change to standard fuel lines instead of the braided fuel line from Canada.

Are those meshy covers on the air horns just protective covers, or are they actually filters?
