Have had the exact discussion with my engine builder. He made a very good piont. He has seen bad batches of E85 ie not enough ethanol and he has seen engines go pop because of that. Rather be safe and a little less power than go pop. The EMS will handle the compression ratio no probs
How's that happen then? You can't put on what's not there if you get me?
I take it the regular pump fuel ain't so good over in Oz then? Assuming that's the reason you're going for E85?
You know more about it than me. Im just the guy who steers it
Lol!
Its a track car im only going for E85 for 1 reason more power. The car has to be NA to be classed under 2L and there are alot of hondas running close to or above 250 hp at the flywheel im racing against.
Well it'll certainly be interesting to see how much power it makes. When's the build happening?
Thats why i love a track only car. I know what I want to achieve and I dont have to compramise...
It will be finished (hopefully) in 2 weeks time. Just waiting for a few parts from the UK.
Season starts in march 2018 so time to have a few shake down track days. Really looking forward to thrashing it up to an inch of its life. Hence the need for safety built in.
The fronts are good. The rears i cant get low enough. Im trying to run the car at the minimum 100mm to ground height with a 5mm rake front to back to get the very very small available underbody effect at that height. Any suggestions for the rears as the springs and shocks are not the traditional coilover setup but seperate. Should i go cook springs on the rear?
For what you're doing I'm amazed that you're not finding them too soft tbh. Only way to get the rear lower is custom rear springs, or go for coilover rear.
Finding it too high? Jc5 106 5th gear will help that. I have part numbers somewhere if you need them.
Cant really tell yet as the car was so underpowered compared to the field. Still alot of fun go carting it around. I usually use my other car a 2011 XKR Jag for track days so its like chalk and cheese. The amazing thing is with only 97kw atw on the original engine it was only 7 sec slower than the jag at phillip island (a power curcuit with lap time of about 2 mins)
If that is known to work that would be fantastic.
The 5th gear ratio on the pms website is the gear ratio you're after mate.
