RB26DETT Posted April 18, 2015 Posted April 18, 2015 Love what you are doing!!! Looking forwards to the end product Quote
Brabham Posted April 19, 2015 Posted April 19, 2015 Why do you run E85 Paul? Is it because it burns cooler/put more fuel through the engine? Looks awesome:) Quote
Retro Z Posted April 19, 2015 Posted April 19, 2015 E85 is usually used for the higher detonation threshold, in-turn allows higher boost pressure and allows more timing and compression aswell. Quote
Agno Posted April 19, 2015 Posted April 19, 2015 You're both half right. E85 reduces the intake charge temperature in the combustion chamber and also has a much higher octane rating than conventional gasoline. Both of these factors lead E85 to be detonation resistant, meaning engines can run a higher static CR, more timing and higher levels of boost. Quote
Ledge Posted April 20, 2015 Author Posted April 20, 2015 Why do you run E85 Paul? Is it because it burns cooler/put more fuel through the engine? Looks awesome:) As the other guys have said. For track car it's the best fuel to run. Quote
PZG302 Posted April 20, 2015 Posted April 20, 2015 Only downside is the extra fuel it burns, about 20-25% more depending on the application. For this reason, my build will be tuned for 98 pump fuel so I can compete in one hour enduros with the standard tank as it is in the safest location in the S14 and a small surge pot that will be within the rules and make sure I get the one hour range I need. For sprint and hill climb events this is not an issue. Quote
dat240z Posted April 21, 2015 Posted April 21, 2015 Oh wow.... That's either a dinner plate sized turbo or the highest set manifold out there.. I'm guessing the first. Looks good mate, that thing will sound like a jet Quote

Looks good mate, that thing will sound like a jet Combination of a few things. The manifold is from raw brokerage in the states. Its designed for rb in z. But we have stood the engine up straight to make a few things work better. This has pushed the turbo up through the bonnet. And yes itis a big turbo Quote
Ledge Posted May 18, 2015 Author Posted May 18, 2015 Peter Mc is making nice progress with the engine. Bottom end is together and the head almost finished Quote
Ledge Posted July 6, 2015 Author Posted July 6, 2015 Nice pic a good mate drew of the new look the car will have. Will still be orange. Quote
d3c0y Posted July 6, 2015 Posted July 6, 2015 Has Freddy designed the aero package for this car or did you do it yourself? Quote
Ledge Posted July 7, 2015 Author Posted July 7, 2015 Yeah Topstage is in charge of that. The pic aero is just a guide for now Quote
d3c0y Posted July 7, 2015 Posted July 7, 2015 Makes sense then, I thought a couple of the elements were a little strange. Quote
260DET Posted July 7, 2015 Posted July 7, 2015 Those wrap over wing supports are the go, apparently the disturbance they cause on top is not as degrading as if they were underneath. Quote
d3c0y Posted July 7, 2015 Posted July 7, 2015 They are called swan necks. The theory is to not disturb the low pressure air and cause the wing to stall underneath due to separation. Quote
Scando Posted July 7, 2015 Posted July 7, 2015 Nice work, I'm tipping you're going to lay down some very impressive times a WTAC this year. Quote
Ledge Posted July 7, 2015 Author Posted July 7, 2015 Wont be there this year mate. Not enough time Quote
Scando Posted July 9, 2015 Posted July 9, 2015 I'm tipping you're going to lay down some very impressive times a WTAC next year then. Quote
Administrators gav240z Posted July 9, 2015 Administrators Posted July 9, 2015 Yeah and hopefully I'll be there to watch, really wish your car was running last time. Oh well... I'm sure you're just as disappointed. Quote
d3c0y Posted July 9, 2015 Posted July 9, 2015 I feel your pain. My pocket died a couple of years back. Quote
Ledge Posted August 2, 2015 Author Posted August 2, 2015 Few engine Progress pics. Getting close now Quote
