    Deedubb's barometric pressure's probably about 25 in Hg, too.

    Just think with a baro of, say, 29.9 ... that's nearly a 20% higher boost figure for guyz at or near sea level.

    A fuel pump will in no way increase horsepower unless you are losing power due to fuel pressure loss.

    Thanks for posting the dyno sheet Clint!

    I have ditched the CAM idea for the time being. I think with Headers and the OD Pulley, I'll be pretty well up over 500RWHP which was my original goal. I've gotta do something about the wheel hop now.

    Re: E85 Conversion on Maggie'd V

    Dee, you've basically got the choice between Kooks and B&B for headers. Yeah, I know TPIS has 'em, too, but Kooks and B&B are far more common, and I'd still with one of those two.

    Ques: Are you at all into having some exhaust sound? The reason I ask is going B&B all the way back will probably yield the most aggressive sound, whereas the Kooks and, say, Corsa will be a bit more tame. If you go with either set of headers and maintain your stock exhaust with muffler delete, you'll save some bucks, and the sound will still be, as heavy puts it, "bitchin'." And the best part is you'll be able to pump air out of the cylinders much more completely.

    The H-E axles would virtually eliminate WH, but spending on those, too, might put you in the poor house (if you're not there already). Specter Werkes bushings would help with a big portion of the WH (ask Tony) and be substantially less expensive, too.

    And your diff? Guess we'll need heavy to come up with a miracle or you'll need to rob a bank somewhere.



    What're your thoughts?

    As far as exhaust, I'm all for loud but honestly the best price will probably yield the path I choose.
    I have not read up too much on wheel hop because I never noticed it much in the past. Now it's a constant reminder. I would think the H-E axles or GE force ones along with some specter bushings would do me justice...if both are even needed. I already made a comment to the wife about the steel diff that nutz has for sale but it almost cost me a black eye!!

    Now if heavy could get something going, I could probably save some coin.

    But next steps for me are larger injectors, 10% OD pulley and headers...in that order. That is unless something cool comes up for sale lol!

    Just tell her you're going to buy the axles with all the money you are now saving in gas

    Re: E85 Conversion on Maggie'd V

    quick question, in a vw/audi you are able to load multiple tunes and then switch b/w them using the headlight stalk so you can run high boost and that tune and go to a low bost setting if you dont have good enough fuel available.

    is that sort of setup available for us to use on the fly.

    99% sure we don't have that option. Been going to the HP tuners forum a lot, and I haven't seen anything about it.

    Dee: NICE!!!
    Quick question on the dyno pulls. Was there a difference in outside air temps between the runs. Oh, and what were the IATs befoe/after.

    As for the injectors, why not just call Magnuson. Tom (510) said that he and I have 60# blue tops in ours. Like I said earlier, duty cycle didn't go over 60% on the dyno.

    After a inline fuel pump, and e85 tune were installed on Dave's CTS-V, did a dyno today as you all know..

    Results below of best run of 91 Oct VS E85 Fuel. "NO" other mods done.
    I'll just bump this post, cuz its so nice looking
    Clint, what software did you use to tune the car?
    I run HP tuners, and I'm curious exactly what the changes are.

    That's my point. Was there potentially an issue with the stock unit ?

    I think this project ought to be named winner of the "Mad Mod of the Year Award" - just beating out asymmetric axles at the last minute.

    I guess 2009 (as much as it sucked otherwise ) has been a good mod year. And if we can get consistant results, this does beat out the axles. Whipple can have an early start at next years trophy.

    I went back to the first post. At $299, this is a very interesting mod. I'll research how available E85 is in NY, but I'm not getting my hopes up.
    Question: The inline pump was rated at 550-600RWHP "on gas". Does this mean the rating is lower with E85, since you need to flow so much more fuel? I wonder if we can get away with using the Magnavolt? Hmmm.....this just got a little more interesting

    I trying to remember what the temps were like the first day we dyno'd...I'm thinking 15 degree difference perhaps. Yesterdays dyno was mid day, while the previous one was at evening time...but its colder now here. Maybe Clint remembers.

    I'll see what Magnuson offers for prices on 60#'ers. I wonder why I got the Green top 42#'s with mine

    As far as your question about the RWHP levels on the external, i believe that is for that pump only. The stock pump remains intact and not touched. They should work together which leads me to believe that the max rated HP would be higher with 2 pumps (stock and inline)...or maybe I don't understand correctly. But what I do know is that its working and not starving from fuel from the pumps...only my tiny injectors

    Frost on LS1tech is currently making dual tune chips for our PCMs. It has been going on in Australia for a long time now and FROST has brought it to the US in an affordable package.
