There is a reason why i'm so persistent on simply getting the engine built and NOTHING more at this time for you dude. Because half of the suggestions you've been given are worth more monitarily then they're worth on stage.
I've spent the better half of a decade studing rules and looking for loopholes, it's part of what i see as my job as a codriver. I'm not the BEST, and certainly i haven't been doing this the longest; but sure as hell, i've been doing this longer then you have. And as an experienced rallyist, who you've asked for suggestion my answer is thus, and always will be, to you on your freshman year of performance rally: Its better to spend money on tires, then it is on engines. You'll get more performance per mile on brand new, REALLY good tires, then you'll ever get on a few hundred bucks in engine mods. If you want reliability mods: go with stock, that's the most reliable you'll ever see THAT engine.
Allow me to itemize:
The engine Barrett had in the car was run for a period with no water in it and then replaced with a worn out engine with low compression in two cylinders prior to me buying it. I'm going to assemble a new engine that will have a good blend of power and reliability.
Yes, I know the engine was run that way. We were ahead of barrett on the road that day, but the stages were run twice and I talked to him at the ATC of the stage the second time through. In summary, i know WHY it is you're doing trying to do what you're doing.
Remember what's going on here - at the root, you're asking for racing suggestions from people who are for the most part not A) familiar with your santioning body and B) are not familiar with the rules run therein.
-Can you use a bigger turbo? There is certainly power to gain there.
Case in point is this question. No, he cannot use a bigger turbo.
-Can you change heads?
Another good point, no he cannot use different heads.
mods that increase reliability
That's why PGT is what it IS. ---Production--- GT. Built to production specs with
minor variations.
RA Bulletin #8, posted 14, Jan 2005.
Subject: piggyback Engine controllers in PGT.
http://www.rally-america.com/info/2005_ ... 05_008.pdf
This bulletin allows you to change the fuel into the engine. Also highlights that you may only use a manual boost controller to change boost pressure; which negates dougs' suggestion:
piggyback, only if going for high boost
basically, you can use an S-AFC from APEXi, but not an AVC-R.
Please now, open your Rally America rulebooks to page 86 and start reading. 10.2.c.8 begins your homework.
"any part damaged through wear or accident may only be replaced by an OEM part identical to the one damaged... All original equipment must be intact and and unmodified according to the manufacturer's specifications unless modifications are specifically authorized in the following paragraphs..."
uhh, well that about sums it up for what's "LEGAL" in PGT for engine work, basically, nothing. Since you've specified you're going to be racing in "PGT," that denotes Rally America rulesets and we could stop right there, but since I'm being cheerful and helpful today, lets move on to NASA. Please open your NASA Rallysport General regulations to page 44 where we begin to read about their Stock Classes, which you will try to fit in under what's called Super Stock 2.
3.2.4.6: Normal work and repair
3.2.4.7: Authorized modifications.. specifically the first line "All items, which are not specifically allowed or referred to as "free" below, must be of original manufacturers specifications..."
3.2.4.7.q: Manufacturer's specifications: Any machining for adjustment must meet the manufacturer's specifications including those for tolerances.
In summary for nasa: Build your engine to manufacturer's tolerances.
Now then, having written all that and reread it for clarity; does what i suggest make sense?
:D:D
The perfect power can run on extra solenoid/injector.
