2285 type 4 screamer motor...

[O.k. i have been playing around with a formula i saw on the web about horsepower and based on this formula if i have 210 ft/lbs of torque to the wheels at 6500 RPM i should be able to make 260 WHP. I want to use the deutz liners to achieve this and hypereutectic pistons with dual plug coil near plug technology running at 10.5 : 1 compression on 90 octane gas, car will be a daily driver.

I know some of you might say that this is a bit too lofty of an idea but i still think it can be done. Roller cams i think could make this happen.]
    

It's a bit odd. but most tend to focus only on hp. But it is perhaps a relic from the time when VWs were built with smaller engines? Now it is NOT to be smart! Only as a question.!!! you said yourself that it's  for the street. And as Udo writes, The figures do not match... If you need 260 WHP. You will have to use a cam in the neighborhood of a fk. 98, and a agresivt Lift, and we'll talk a comp. of 11.5 or 12.5: 1.          max hp. at 8500rpm. or more ... (feel free to comment, "bad bug", Udo and Jakob!)

 You MIGHT have a 271nm.(6500rpm.)   260whp. (8500rpm.) 2.7 liter engine??....
 But you CAN have a 328nm. (4900rpm.) 245 hp. (5900rpm.) 2.7 liter engine!!!!

 ok, mine is a type 1 with JPM heads, but I'm sure jakob can create a type 4 for you coming very close ....!
  only difference will be the type 4 will be even better on the street (cooling) And I run my own in heavy traffic, or on the highway all summer!

It may not sound very much compared to your 260whp. But I tell you, it pulls like a freight train!!!!
 And the nm. makes it SO easy and fun to drive on the street ....

 P.S. sorry Jacob, that I make a sale ad without talking to you, in your own thread ....  

Don't want a rever just want something that has torque and move well, also it wouldn't hurt if i could demolish evo's and subbies when i feel like it.

Car must be daily driven. Magic that's 241 ft/lbs of torque, god that's a lot.

  yearr ... that's what you get if you go for the nm. (or ft/lbs... .) in a 2.7 (or bigger) 4 cyl. motor ... Think about it, the engine gets 686ccm. per cylinder and 84mm. in stroke!!!
 (a type 1 that is)
But hey, Jakob can make you a 86 * 105 type 4 if you now think that 2.7 is too little....   ....  Is'ent it a little strange, that there ain't more people who try this route?

Jiharrr.... ´just bring them EVO's....... (what is subbies?  )  i have set my rev. limiter at 7200, and practicaly never hit it..
 When I'm not just out fore heated driving, then i can actually run it like a large modern disel engine, it is that easy, and it is quite indifferent which gear you put it in....
 it can run at idle.... ok, 1100rpm then... (idle is 800rpm.) up small slopes.....(hmm, how do you say this? ..... increases )... and yet, it rev  SOO fast if you floor the laud pedal

A subbie is a subaru impreza. I am also a fan of the diesel effect with these engines but doesn't the 86mm crank have too much flex. With an 86mm crank you will need expensive rods such as pauter rods to clear the cam lobe.

[Udo]

If you do not want to spent money for pauter rods stop your thoughts. An engine like this is very expensive

Udo

[Bad bug]

I know they are expensive that's why i want to do an 80mm stroke engine if my 2 71mm cranks aren't good.

Hey Bad Bug.

 Thanks for the explanation about the Subaru im.....!
 Now I'm not so tough when it comes to type 4... But is it not 82mm. stroke, you can go up to, before you have to step up to the expensive rods?!
 About flex in the crank, then you are of course somewhat protected, if you build an engine which should not take more than 7500rpm.!
 and now, If you use Deutz cyl.... And( For type 4) the now new (and quite ordinary) H-beam connecting rods..... maybe 105mm. Pistons from a v8 ..... Hmmmmm....!!!
And I know it can be done .... Jacob has already built such an engine!

Yes you are right 82mm crank with 5.5 h beam rods. I wonder if jakob used 105mm forged units all the time when he is building these big engines or does he use cast ( hypereutectic units ).

[GetBackOnTrack]

Fired up this freshly build type 4 engine a couple of days ago.

Here are some specs:

2366 Type 4, 71x103
Wiseco pistons/deutz cylinders.
318 euro race cam.
44/38 valves.
comp 11:1.
48 idf webers.

should be in the 200 hp range.

Jakob did you have any piston rock on the 105mm pistons also did the 105mm use .927 inch piston pins.

Pauters are not expensive, carillo and cunninhams are ..

Hi Jakob,

New engine sounds and looks good.

I am collecting parts for a similar engine, 4inch (with 101.6 JE pistons) type 4 engine,
already have a set off 100mm deutz cylinders.
But does the csp kit clear the Deutz cylinders? (on the picture it looks like it).

Keep pictures coming very interesting.

Regards Edgar

[GetBackOnTrack]

Hi.

the pistons use 22,16 mm pins.

The csp kit clears the cylinders pretty good, a little craftmanship is needed though.

Regards, Jakob.

Just finished the conversion of this water case into air, today.

[GetBackOnTrack]

The case got new lifterbores for type 1 lifters aswell.

[Mags]

Nice Jakob
see you Friday 6July.

[Bad bug]

Nice work jakob.

[GetBackOnTrack]

Just installed new alubronze seats for 48/38 valves, in a nice set of porsche 914 heads today.

Regards, Jakob

Jakob, your work is second to none...I love it.
