i agree about the mechanics....all they really know about are T1's. my mechanic didnt even see how it was preferable to use a T4 instead. im looking to put in a 2.0 too....but funds lacking |

Krems where in Kingston are you. The conversion may not be all that expensive if you can find 2.0ltr bus cylinder head tins. Jake sell a book which tells how to do this.

i have Joe Cali's book, and i can find an engine with little prob...just need the dual carbs, to fabricate an exhaust....do the necessary work (lighten the flywheel too) and go.
im in Mona any advice/suggestions? to keep on topic: nice shroud, wonder how it'll do against the DTM. by the way, Jake, i remember some time ago you said you hadnt tested the dtm against the Cali conversion, have you done so since then? |

Krems: To find dual carbs check Peter or Morgan on Red hills road by the Price Right suppermarket, they should be able to help you out. Thank god i have my dual 44 webers the price for new carbs now is rediculous. Do you have a flywheel as yet if not get an 1.8l flywheel and you are set if not the waterboxer flywheel can be used with a cars starter its 228mm ( more clamping force ). About the exhaust thing i was going to fab mine i have to buy 1 5/8 stub pipes form jake, the bends can be sourced elsewhere. Krem if you lighten the flywheel get everything balanced this should be done on any engine built. The mechanics hear don't tell you this they only put your engine together as best they can and bang 6 months later you are out of an engine, yes i know we don't have balancer in Jamaica but spend the money and check jake out. I am curious to see how well sandeep's engine cool after the modifications to the shroud.

5 blade cooling
what kind of performance does the 911 5 blade have? will this keep a 2056cc cool with a 96plate mesa with fan?

The shroud with the mods to the back of the 911 fan is working great. The hottest temp I have to date is 361F on #4 at 17 psi, 5400 rpm in 4th.
The car runs awesome with the turbo with temps averaging around 320F while driving around town. On the highway they average about 340F with all cylinders within about 10F of each other. The Megasquirt EFI really helps as well, as does the LC-1 because I can dial in exactly the A/F ratio I want. The EDIS helps as well because of the programmable ignition. I really did not know what A/F ratio I was running with the 44IDF's and not exactly sure of the timing with the 050 Dizzy, because the temps I am getting with the EFI/EDIS/Turbo are close to what I had with the 44 IDF's/050 Dizzy/No turbo. So overall, I am extremely happy because I KNOW I have a 911 shroud that cools well enough for me to run a turbo at 17 PSI Engine is currently apart to fix a loose valve seat and is getting an overall refresh. Will be terrorizing the streets again in spring 2007 Sandeep sandeep |

I think I have a clua why the FAT shroud works well. Like the type 1 shroud, it guides the air left and right untill it dumps it onto the heads.
Here's a comparison of a different approach to mimic the original porsche air deflector. Both are Remmele shrouds. The blue shroud is actually an adaption of a Remmele shroud for an Ahnendorp machined case. However, the only 'remmele'touch is that it has a more flat (hollow actually) back side, intended to divert the air better to 2 and 4th cylinders. The second one is an all original Remmele shroud (the carbon one). There the flat back is even more pronounced and it also has very distinct 'paths' to direct more air to 2 and 4th. I have no conclusive data in the forms of temps on either tho. That will take time Best regards, Walter |

Off the shelf, the FAT shroud was the worst shroud I tested for temperature delta, despite the drive ratio or amount of blades on the fan it always kept the same delta. I have seen #4 more than 150F hotter than #1 with that system and no mods made to it.
