    E85 7th injector? Has anybody seen e 85 injected pre turbo?

    The power to drive the compressor depends on the mass flow and the efficiency, not sure how that is effected by spraying in front of the compressor, but I am guessing the impact on compressor shaft power required is negligible. I can't say if the alky pump will like e85 (15% gasoline), that...

    E85 7th injector? Has anybody seen e 85 injected pre turbo?

    What you want to look at is the latent heat of vaporization. Specific heat or heat capacity of the liquid plays a negligible part. The latent heat of vaporization for Meth and E85 is close, so you will get a similar benefit for cooling. Meth can run way richer though than E85, so you will get...

    Procar Elite seats please chime in

    I have been distracted with dirt bikes for awhile, but I am planning a small over haul in the not too distant future. The aims will be to make the car more street-able. New seats, restore the AC, put a street oriented rear sway bar back on, maybe a few other things that need attention. Also...

    Any financial gurus? (Doubt it if you have an 80's buick lol)

    You should look into the plan to make sure, but if you leave your current job or are let go you can draw from that employers 401k penalty free if you over 55. You still owe the normal taxes. It only applies to the your current employers 401k, not money from a previous plan. 59 1/2 is still...

    Total Frivolity

    I really liked the Beta, put about 200 hours on it, but this KTM kicks ass.

    boost problem

    Thinking out loud, whatever is causing the problems is resulting in fluctuations. An exhaust leak would result in a steady drop, unless it was acting like a relief valve opening up under a certain pressure and then seals back up. Or the leak would have to cause something else to change...

    The First Comp Turbo CTRX Hubless

    Hey Sam, that is good data! Both of those are good indicators.

    boost problem

    Hey THensley, Was the first screen shot the first test run, i.e. was the car started cold and this was the first full boost run? Is the boost control an open loop pulse width modulation from the Holly ECU? By the way, nice job on the 10 second pass with the 5857.

    The First Comp Turbo CTRX Hubless

    In that photo we can only see 1 hole in the impeller, I assume there are evenly spaced holes, so 3 or 4 more holes? The ribs in the impeller may be for strength or maybe for aero effects, unless we can talk to the designer, impossible tell. Laminar vs turbulent flow is a reference to the...

    Total Frivolity

    I decided to keep the dirt bike thing going. Sold one of the Betas and picked up a new bike. Left over 2024 KTM 250 XC. Big step up from the Beta 200RR. Hopefully no injuries this year.

    Good morning, Americans...it's FRIDAY

    Waaayyy to difficult. The other 4 year olds never understood what I was doing when I took a big hit.

    Good morning, Americans...it's FRIDAY

    This is based in Einstein's theory of special relativity. It has also been observed experimentally with regard to particle physics and is even used by GPS to provide accurate location calculations. Simply stated, as your velocity increases, the time you experience is slower than the proper...

    engine noise

    Hard to tell from a recording, but unless you can definitely tell where it is coming from I would take the accessory belt off and start it just to rule a bad accessory or rattling belt tensioner. Then start looking internal.

    Constant 2004R issues.

    Hi Steve, Dave Husek did mine, you are welcome to test drive it. It is awesome. It is tough to drop that kind of coin and have it not work, but if you give it to Dave it will turn out right. Plus Dave always picks up the phone or promptly returns your call.
