107mm Nickies! Pushing the MAX!

Post by MASSIVE TYPE IV » Thu Jul 27, 2006 9:32 am

And all for an engine that will be at least 3.1L... Cylinders will use the stock stud pattern of the TIV!!!!

A few weeks ago I had a customer request the "biggest engine we would build"....

He is a great guy thats very easy to work with and was willing to take the risks involved. He currently has two RAT engines being built, the other is a 2615 for his Beck Speedster so I figured "what the hell, I'm gonna hook this guy up.."

So then I started the planning, ordered some parts that take a while to get (6 months) and called Charles to give him the good news that insanity was on the rise and we needed to up the ante!

Yesterday he finished the design of the new cylinder on paper and they'll be spit out of the CNC in the next week or so as the biggest Nickies to date and definately the biggest we can do to a TIV that retains the stock bore spacing and stud pattern. The way we are making this happen is requiring some machine work, welding and "tricks"...

Based on the excellent results we have attained with the 105.07mm Nickies I feel confident that these babies will be just as perfect! The piston being used is 4.210 (damn near a 4-1/4" bore) and is in the design stages now as far as it's forging and etc is concerned.

This engine will more than likely end up at 88 stroke with a roller cam and the set of Engine Plus heads that I bought from Alex to test against my Billet heads.. But many things are still up in the air at this point including the heads, but since this engine is not due for 16 more months we have plenty of time to do more developments to apply into it's composition.

We'll be posting about this one as it evolves for sure!

BTW- The customer doesn't have a vehicle to put the engine into yet, I'd love to see it go into either a bad ass German Looker, OR a very authentic Cal Looker and that would be just to piss people off!

:D
Get some photos of them next to some stock size ones... Would make for an interesting side by side...
And then also next to some stock T1 ones ;)

OMG! Please keep us posted
Wait, 88x107=3,165cc Geezus!

Its probably going to be 90mm stroke...

The rollers allow us to do so much more with the cam that gross lift isn't needed as much at the lobe...

I have a '54 Cal Looker and am not far from you. I would be happy to break it in for him for a year or two. :D

Can you put boost to something like that?

Not these... No way.

Turbo engines don't need big bores to make big power anyway, our Turbo cylinders are 91,98 mm and 100mm.

Wouldn't twin spark be very, very worth your while on such a large bore?
What CR do you (dare) run with these large bore/thin wall alu cylinders?

Cool project. Good for some back to back testing of stuff also :wink:

I wouldn't mind if you used this thread as a project update thread :lol:

Tnx,

The cylinder walls are actually the same thickness as a 105 - we've bumped out the registers to maintain about the same rigidity as a 105, but at 107, by also making the fins shorter. I've made the cylinders longer for the planned 90mm stroke too. From the late model 911 stuff i've done, I know that there will still be more than enough cooling fin area. Needless to say, Jake will have his hands full with some creative engineering when it comes to the heads and especially the case, but all do-able with a little patience. Twin plug would be nice, but since we're keeping the compression reasonable, there really would be no need - just zero deck and we should be golden! And yes, these cylinders will obviously be cyrogenically treated. Another variation will be the omission of the windage notches, among other small changes here and there. We should have cylinders by sometime next week :-)

As always it's great to work from scratch with Charles.. Between us we can cook things up easily and quickly most of the time..

Oh yeah, I'll never build another 105+bore engine without twin plugs after the mighty spyder and the huge benefits we recorded with it..

This one is most definately going twin spark.

BTW- CR isn't going to be conservative, Charles... Len and i chatted yesterday and with twin plugs we'll be running 11:1, maybe a tad more on this bad boy...

The customer lives in Hawaii and has the perfect weather for making HP and keeping the engine cool, plus he can't go more than 11 miles without hitting the Ocean from his house so heat won't be an issue, plus its got a DTM..

everything now depends on the cam, we are making up a dummy 90mm crank for camshaft design so we can run the case mock up assembly down to my local camshaft guy and have him make us a roller cam that fits the bill lift wise and clearance wise, then we'll go from there to manipulate the grind..

Being able to grind a cam on the spot and fit it right into the engine has so many benefits:-)

Woohoo! 11:1+, I can't wait. :-) I'm sure Len has something under his sleeve.

With the engine living in Hawaii and the customer wanting everything we can give him we decided to bump things up just a bit, especially with the dual plugs..

I hope the customer decides to have the car shipped to Atlanta for NoH20 to do the install (at this point it looks mandatory with all the craziness) because I'd love to get some chassis dyno numbers from it, or take it to the SE Dyno day!
