Well I was out this weekend and got the chance to ride with a aero charger etec and I am not sure if it will work like that everyday but if it does then WoW! It was very impressive
i had your issue, but with some fine tunning it is sweet, i removed the intercooler, and did a few other mods, hessitaion is almost gone, and spools dam quick, my a/f is around 12.8 and would like to get it to 13
boost is around 7lbs.. plan to try it with a air to water cooler for next ride, to see if its even better
here are a few vids to here the response
Which water to air kit are you planning on running?Also have you or anyone else monitored boosted air temps without the I/C and with where it enters the airbox? Just wondering how efficient the I/C actually is at low boost in these sleds.
went with a barrel design air to water intercooler but its not installed yet, plan to use front heat exchanger to soley cool the water for intercooler
here is some info from brad at aerocharger on the charge temps
We currently use Air/Water in 5 applications. We are also currently testing Air/Water systems on the e-Tec. An A/W system will ONLY be release if the testing performs within our design parameters. Our current system was not intended to have an A/W system because BRP had certain requirements for the system specific to the Race Team.
Current water pump is a Bosch pump. Be careful of the amps!
A 1.1 psi pressure drop is probably not accurate and is excessive.
Here are some of my calculations and assumption that may be helpful.
800cc E-Tec, 7000ft or 11.3psia, 34f Ambient air, 110f engine coolant returning from tunnel (from test data), Water temp on a dedicated system 32f (again from test data), 10psi, 1.88 P/R, 12.8afr, 72% compressor Efficiency, 70% intercooler efficiency, and .5 pressure drop.
No intercooler, 307cfm, T2 170f (Compressor Out), 170f Charge Temp, and 213hp at attitude not corrected.
