2285 type 4 screamer motor...

[Harry/FDK]

Jakob, do you mean the sparkplug caps to be bend ? I think i'll have those. Their straight but you can bend them within reason.

[GetBackOnTrack]

Hey Harry.. I allready have the msd wires, they can be slightly bend, but cant make them click firmly around the spark plugs.. Which ones do you refer to?

Regards, Jakob

[Harry/FDK]

Now i understand, i will see what i have and get back to you.

Harry

Hi Jakob,

I know that Mallory makes wires with straight, 45° and 90° ends. Maybe they have the right wire for your application.

Bye,

Tobi

Jakob, any news ? (PS. PM to your private mail)

[GetBackOnTrack]

Hey Harry.. Still waiting for header and spark plug wires..

I cant see your PM by the way, have you send me one?

Regards, Jakob

[Harry/FDK]

I just did one again,

Harry

PS. What happened to your website ?
PS. Let me know please ?

[Harry/FDK]

PM .

[Harry/FDK]

Please Turbo Thomas, could you get Harry and GetBackOnTrack exhaust systems done please ? Mock-up time ...

[GetBackOnTrack]

Did a break in on the engine a couple of days ago, I have a small video of it, but dont really know how to upload it in here, if anybody have an idea feel free to come with hints.

[Blob]

Up-load it to youtube, and then make a link

[Harry/FDK]

Jakob, any updates on your T4 screamer ? (I received my exhaust system as well).

Regards,
Harry

[GetBackOnTrack]

UPDATE...

Have taken the engine apart cause it was leaking between cylinder and head.. Found out that the exhaust valves had hit the pistons..

Have had the valve sunken 0.8 mm into the seat to clear up some space between valve and piston and to make 2,2 mm clearence at full lift before coilbind. And have now installed titanium valves  Around 50 grams lighter than the steal valves I had before.

Have machined the cylinders for a ring to be put in there in an attempt to try to make it not leak, and it WORKS so far.. Have had the engine started up again today and it runs with no mis sounds, very nice..

It eats rpm out of this world so need to install a switch that makes it rev no higher than 8700 rpm, or I will blow it up..

It needs fine tuning now.. It will not fall down in rpm when I let off the gas.. think it needs more fuel..


Regards, Jakob

[Harry/FDK]

What material did you use for the rings on the cylinders Jakob ? Stainless ?

Harry

[GetBackOnTrack]

Hey all.

I finally got this engine to work after a lot of experimentation.

Just came home from the dyno yesterday. The engine has been changed to 71 stroke instead of 66 as well as carbs has gone from 62 terminators to 51,5 Idas. Else from that the engine is like described and pictured in the thread.

The engine volume is now 2460cc and it pulled 254 HP and 265 NM WITHOUT fanbelt (Engine was HOT at this final last reading). And 245 HP with the belt on. As you can see from the dyno result the engine responded well when we took of the belt and made a final run (Grey line), There might be a few more ponies in it if we had put in even a bigger main jet. Jetting is 220 main and 195 air.

A video of the engine in action aswell as flow tests of the heads can be seen on my facebook site. Just type in GetBackOnTrack in the search field on facebook and you will find it.


If you need any engine work done, please feel free to contact me. I do everything from headwork to complete engines in my own machine shop.

Best regards, Jakob spring (GetBackOnTrack)

Did you do all of this at the wheel. You also said that you had to cut a ring in the liner to seal the head and the sleeve together was any matching ring cut in the head for sealing. Would you build another of these engine wit a bigger crank say a 80mm or 84mm.

Whats the piston skirt to liner clearance on this engine.

[GetBackOnTrack]

hi Bad bug.

Power is on engine, not wheels.

Noting special was done to the heads to make them seal up, just the ring in the cylinder.

Drop me a mail if you are serius about having an engine build.

Regards, Jakob

[Bad bug]

Getbackontrack i wrote you the other day and didn't get any response.

[GetBackOnTrack]

Hmm you must have enteret a wrong address..

Please try again, my mail is gbot@live.dk

Best Regards, Jakob

[Udo]

Looks like good power. original heads can make power, this is what we found out too . all the aftermaket heads offered for typ4 engines are not made for power... only pauter's work nice

Udo

[Bad bug]

Yes Udo i am looking at this and i am impressed.

Sent email again using same email address.

[Udo]

I have some 2,7 with 250 and 260 hp on the circuit track and street. all with original heads 

Udo

[Bad bug]

Udo do you do twin plug heads. What i would like is a 2.7ltr t4 engine that gives 200ft/lbs to 220ft/lbs of torque with 260 to 270 wheel horsepower all in at 6500 RPM.

Wondering is this possible. If i am not building a 2.7ltr engine then i will build a 2.4ltr with twin plug heads as i have 2 71mm cranks.

No,i never did 2 spark plugs. 260 wheel horse power at 6500 is impossible.

Udo

[Bad bug]

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.   

[magic]

Hi Jacob,

 congratulations on the numbers!
 In particular, the 265nm. Quite good for an engine with that cam and 71mm. stroke ....! 
 And that is indeed what makes your car kick ass ..... For it does! Thanks for a great ride. 

 See you,  magic.

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 ....

Magic

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