Hello, In September we was at the Dyno in Luebeck (Germany). I would like to show you the results and I’m happy to see some increased numbers instead the dyno runs from 2009. I will open another thread where I will post the new specs and some pictures... All runs in fifth gear... Power @...

After I red this, I checked what "the backspace clearance" is. Because I have custom CP pistons too, I'm very interested in your research. What I found in the net is an article from MAHLE where they did some testing with different backspace clearance. It's not for race engines, but why should it...

Hm, good question. I build mine in the beginning of 2009… ;)

Hey Patrick, nice to hear that your beast is running...! If possible please show us your dyno results/sheet... and your actual setup (cams, injectors etc...) BTW nice rims...!!! ;) Alex

You are f**king crazy man!!!!!:eek: I like people who do crazy things...And your project is amazing!!!! Thumbs up...!!! :blindfold::cool: Let us know how the party goes on! Alex

Kriss, perfect!! ;) Thanks for the details. But I was unaware that you machine your sleeves too. Now things have come full circle. It's a good solution but there is a lot of work to do before. The Helicoflex O-ring is a "put all together on stock block and heads, torque your studs and be happy-...

Hey BigKriss, that's a very good idea! Many thanks for your pics. But I have some questions. ;) I add a drawing where I show the profile of your seal ring like I understand it from the pictures. Please correct it if I'm wrong. Maybe you would give us some dimensions I marked in the drawing to...

Hey John, yes...it seems that we have to go our own way. I don't want to pay $600 for that Phuzion HG like Carlos said. My old .051" MLS HG laying around and I will take a look how I can modify it to the needed diameter of about 92mm for the O-ring. I didn't get an answer from Garlock yet but...

I called Garlock here in Germany and asked for the gas filled O-rings. I'm still waiting for an answer but the chance to get the O-rings is very good. They can do every diameter (cylinder bore) we need. Thickness of the O-rings are available in: 0,9 [mm] 1,6 2,4 3,2 4,0 etc So it seems Cometic...

Calros, I'm a little bit confused that you have got a positive feedback from Cometic about our 1UZ head gasket. I charge a friend in the USA to ask Cometic for the Phuzion HG for the 1UZ and they told him they can not offer the Phuzion for this engine. :confused: Yes, you are right it's very...

Hey Carlos, check this links about O-ringing: http://www.highperformancepontiac.co...ade/index.html http://www.hotrod.com/techarticles/e...ets/index.html ;)

I used the 10mm ARP2000 stuts and boosted the engine up to 1.3bar and had gasket problems (compression gases in the cooling system). I torqued the stuts to 60 ft lb so I think a little bit more torque (70-75 ft lb) would help a little bit. But I think it's not safe. John use the 12mm stuts and...

Yes John, you are right. I'm curious too if there is a way for those who need thicker gaskets. It looks like there is only one thickness of .051" (1.3mm) available... :mad: My last blown gasket was a Cometic MLS .051". But after machining the heads and blocks surface I would prefer a thicker...

Cometic MLS Phuzion Hello community, today I emailed John with the head gasket sealing problem and after that he started this thread. I did a little research and found out that it seems Cometic know the sealing problem. It's a little bit funny because John told me something about Helicoflex...

Yeah John, you are right. That's my plan too…;)

Car with Work wheels Here are some pictures of the car with the K-Sport coilovers installed and the 9.5 & 11x19 inch Work Rezaxx wheels:

K-Sport Coilover Kit And one more picture of the rear coilover

K-Sport Coilover Kit Hey Guys, I bought a K-Sport Coilover Kit a few month ago. The handling is very good but I have to do the setup next year. Here it is new in the box: Rear: Stock vs. K-Sport Front installed: Rear installed:

Pictures are back! ;)

At the moment two walbro pumps are ok. But I ordered a 3rd one and will install all three pumps in the fuel tank. Here's a picture of the second in-line walbro pump under the fuel tank Alex
