Mega test work underway (Round #2 for my 2316)

[MASSIVE TYPE IV]

The 2316 TIV in my 914 has been together for 2 years..... It was originally designed to be a test combo for my 2316cc series of engines..

The results were good enough for me to create the combos for use in 914s, and then they branched over into the conversion world and I made up alot of them for Speedster and Spyder applications.

Since this was the first 2316 of its combination I learned alot from it, and I was never totally happy with it. It seemed to burn a bit of oil and just didn't have the oil pressure that I like to see. It also had a tendency to run rich, so I knew that the combo was a tad off... the engine is mechanically sound and revs clear past 7500 RPM like nothing, the power is great and exactly what I needed for the application- BUT I know we can make it better!

Well now its time for round #2, and I'm doing some things that will make this engine awesome! This was all isnpired from the 2316 that we did last week and dynoed with outstanding results! I learned something from that one that I want to incorporate into mine because it is being purposely built "Dual purpose" for street and track time at the road course. I need a rev range to 8,000 RPM, and right now she shuts down at power wise @ 6800, but will spin to 7,500 with valve control.... Its good but not good enough.

The new 2316 will see a set of aircooled.net squishies.... a set of LN Engineering Nickies in 96mm AND it will end up getting ceramic lifters and a new camshaft to promote the "Squishie" design.

This engine in its first combination produced 181 HP and 161 lb ft of torque... The new goal for it when totally dialed in is 200 BHP and 180+ lb/ft of torque and a rev range clear to 8K... We will be running 11.8:1 static CR on pump gas, if I can make the combo work the way I want! This will be the first time that Squishies will have ever been used in a TIV engine.

When this engine is all finished and dialed in it will go back into my 914, and end up getting squirted with a 75HP shot of NOS... The engine will be monitored by a safeguard and mallory hyfire with retard.... That should be a true riot!!

Here are the specs:
80x96
5.325 rods (H Beam)
22mm pinned 96mm squishies
96mm Nickies
11.8:1
2.0 914 heads massaged by HAM with 44x38 valves
RAT 290 series camshaft on 114 centers and retarded 3-5 degrees
LN Ceramic lifters, and lightened stock rockers
Full DLC coatings on all bearings and thermal barrier coatings for the combustion chambers and exhaust ports

Tangerine "superheader" with phase nine and quietcan for the street..

Big Thanks goes out to John @ aircooled.net for continued support and for having the TIV squishie pistons made for me

Charles @ LN Engineering for getting me a set of 96 Nickies sooner than I expected, and having my lifters custom made "for my 3.0 engine"

Chris @ Tangerine racing for making the most awesome exhaust on the planet, and providing me with a system dedicated to my dyno that even includes a phase 9 silencer

AND Len from Hoffman Automotive machine... For getting my test work in and out fast and clean and supporting me with your cylinder head work.

These companies and their co-operation is keeping the world turning and the VW hobby expanding! (and keeping me up way too late- Yikes its 3 am, better go grab a power nap)

Jake i have been dreaming about an engine like this if this combo work i will build an engine like this.

[Ephry73]

Man that sounds like a sweet combo Jake! Sorry I got to this late. Now, have you used a 5.5 rod with this? I know this may throw the whole thing off, but just curiosu if you had. How much will something like this run for as a kit form from you?

A 5.5 rod in this combo would kill the piston speed and acceleration.. The way this engine spins up is the most amazing part of it.. It would require another whole series of cams and head work...

I tried one with a 5.5 rod and everything else the same and was so disappointed that I tore it down and swapped to a short rod again.

It woukld also require more than .160 shims and would require lengthened pushrod tubes. We already run the highest pin height we can.

[Ephry73]

WOW! it's definitely all in the mix for sure! Jake, you definitely keep us Honest!

SO, say for a Ghia with around 1900lbs with driver and stock ratio tranny(hypotetically) would you go for a 2270 or a 2316? Both for weekend fun and daily driving duties during the week(I like to cruise at 85MPH highway patrol permitting)




E

[MASSIVE TYPE IV]

Forget the stock ratios. They are made for an engine with 80-100 ft/lbs less torque than this.. Running 85MPH with stock gearing witha big TIV kills the power, gas mileage and heats up the oil from all the added RPM.

[Ephry73]

That's what l thought.

Jake, how are you getting that much torque (180+ lb-ft) from a 4-cyl through a 901 transaxle? Sixes get away with it b/c it's less torque per cylinder.

I've been thinking about 150 lb-ft is the limit for a 901 using first gear. Or are you not using first gear?

Joe

[jzglinicki]

Thinking of it from the opposite perspective, I'm thinking that the preferred engine for my 914 would quickly get close to the limit of torque that the 901 can handle, and stay there through 6k - 6500 RPM.

From your experience, what is that torque limit and what would be a good RAT configuration for achieving what I've described.

Thanks Jake!

I seldom use first gear, unless I just want to amaze the passenger when the tach bounces off the peg. Both times that I have screwed up second gear I have been seriously abusing the car. Once was when I was doing 7,000 RPM doughnuts on a backroad and sliding backward at 6K when it let go..

When I use first I make sure everything is meshed before I slam the power to it.

[Ephry73]

Gear ratios and engines, another topic for sure.
