Re: Porn Star Racing.
So what work was done to the head, cam size etc
Need photos of it installed so we can see how it fits in the engine bay.

Re: Porn Star Racing.
Stock 99, Cams BP5A.
Heads been shaved, 7 angle grind on the valves and 16 new valve seals.
Not going to be a fruity as yours. Stock bottom end, with 130kms s as F#CK on it. Trying to build a good motor for MSC race series. My 1600 while good, the Cams eat the HLAs. So every 4 hours of track time I'm pulling the HLAs. So I'm hoping for the same HP, but less maintenance. Better K.P.Is and O.E.E
Machine work has been done by Glen at the torque team. Really happy with his work.

Re: Porn Star Racing.
i suggest manifold and using the turbs too for double awesome.
98 evo gold - rotrexed and loving it.

Re: Porn Star Racing.
Whats the atmosphere to valve length there?
Looks nice and long.

Re: Porn Star Racing.
This is a BASIC article written by Jenvey on the length of ITB's
1) A larger bore leads to lower flow resistance, but obeying the laws of diminishing returns.
2) A smaller bore leads to better throttle control and response (never underestimate) and improved fuel mixing.
3) The system should be considered in total - from (at least) trumpet flange to cylinder and proportioned accordingly.
A guide figure, from the face of the trumpet to the centre of the valve head is 350mm for a 9,000 RPM engine. Other RPM are proportional i.e. for 18,000 RPM the figure is approximately 175mm.
The air horn serves three main purposes;
1) To convert the pressure difference between bore and entrance into air velocity with the minimum of energy loss.
2) To act as the interface between the induction system and the atmosphere, i.e. the point at which pressure waves change sign and direction.
3) To complete the system to the required overall length.

Re: Porn Star Racing.
WWWWWHHHHHAAAAAATTTTTT! What happened to the turbo idea? I thought itbs were too expensive for porn star racing's budget?
I'll need to come over and check them out at some point. They look pretty cool. When is the engine going in?

Got some more pool cleaning money
I got pissed off with the VICs manifold and ITBs are NA porn

Re: Porn Star Racing.
Gotta admit, I'm a little disappointed in this thread based on its title.
Don't worry about dying, worry about not living!
