Simple 300whp recipe. K24/20 with all shelf parts. Also Dc4 vs Ultra 2 graph
 

Recently I got to work on a very simple setup that ended up making decent power. I figured i'd share the recipe and results with everyone.

K24 Block
- 87.5mm Wiseco 12.5:1 Pistons
- Skunk2 K24 Rods
-K20a2 Oil Pump

K20a2 Head(stock cast)
- Supetech Valve Train w/ Stock Sized Valves
- SKunk Ultra 2 Cams (50* VTC Gear - pinned to 35*)
- Skunk2 Ultra Intake manifold w/ 90mm TB
- Skunk2 Alpha Swap Header

Its on Grams 725cc Injectors running E85

It's a lot of Skunk2 parts that happen to work and work well. I was surpised that the header would hang at this power range. Im curious if with a nice custom header if there is more power to be found. The owner of the car is very happy with the results and overall feel of the car.

Also as a sidenote we originally used to run Drag Cartel 4 cams in this car and ended up swapping them out for the new Skunk2 Ultra 2's. The gains were incredible. These are my new go to cams. Here is the back to back comparison.

*No changes were done besides the cams.

300+ whp with off the shelf parts is not easy.Props to you Mikeyspec

Awesome test and build guys. I want to see more info and tests of the new skunk cams. I looked them up on the website but no specs listed -_-

Re: Simple 300whp recipe. K24/20 with all shelf parts. Also Dc4 vs Ultra 2 graph
 

I thought I saw a chart on skunks website with all the ultra cams specs listed last night.

Here It is.

No chain slap like with the older skunk2 cams?

Re: Simple 300whp recipe. K24/20 with all shelf parts. Also Dc4 vs Ultra 2 graph
 

Jesus Christ, those Ultra2s have 13.2mm of lift and 278 degrees of duration.

Very nice power! Did he get to the track before and will he do an after with the extra power?

I have the same dip up top with the Skunk 2 Ultra. Good to see one of the first dynos of the Ultras. I have some Ultra 4s waiting to go on once we get some free time!

solid work
do you recall what's injector duty cycle on those injectors with that power level and e85?

Re: Simple 300whp recipe. K24/20 with all shelf parts. Also Dc4 vs Ultra 2 graph
 

Nice work, Mikey.

What fuel was this on? 93? E85?

Re: Simple 300whp recipe. K24/20 with all shelf parts. Also Dc4 vs Ultra 2 graph
 

It says e85

Re: Simple 300whp recipe. K24/20 with all shelf parts. Also Dc4 vs Ultra 2 graph
 

I would love to see a Pro163 head on that, really nice power for what it is. Can't wait to see some BMF testing.

Wow. Solid work my man

Awesome. Would love to see b series testing of these cams

Re: Simple 300whp recipe. K24/20 with all shelf parts. Also Dc4 vs Ultra 2 graph
 

Great numbers! How much would this setup cost to replicate?

Re: Simple 300whp recipe. K24/20 with all shelf parts. Also Dc4 vs Ultra 2 graph
 

Considering it's 'off the shelf parts', why don't you price it out, and figure it out yourself.

^ lol

Re: Simple 300whp recipe. K24/20 with all shelf parts. Also Dc4 vs Ultra 2 graph
 

whoa, nice power man. First real info I've seen of the skunk2 ultra cams, starting to think no is running them lol

Re: Simple 300whp recipe. K24/20 with all shelf parts. Also Dc4 vs Ultra 2 graph
 

great work as always mikey, there is alot of hidden power waiting in that setup.

Re: Simple 300whp recipe. K24/20 with all shelf parts. Also Dc4 vs Ultra 2 graph
 

Can I copy your build? lol

What you think it will run threw the 1/4?

Re: Simple 300whp recipe. K24/20 with all shelf parts. Also Dc4 vs Ultra 2 graph
 

Sick number. I think these are the cams I'm getting now.
