Hello/Beat that dead horse again!

[Mike Rolica]

Yes, 30lbs at what psi-39( stock) Like mine, 24lbs should be good for 384 hp
but at 55psi= 29lbs which is good for 464 
Also remember that a naturally aspirate has a BSFC of .45.  Super natural
:-) has about a BSFC of .55 (from most testing and reading I have done.  So
to achieve his 600-650 hp he would have to have his 30lb injectors set at 74
to 94 psi!
Is this a DI motor? (direct injection):-)  I smell something Bruce....What
is it... it is coming from the screen!

	Well, I got some good news an some bad news.

	Eight 30 lb/hr injectors it a total flow of 240 lbs/hr, at .5 per HP
	that's 480, and heated of the intake air from the S/C might drop
that.

	Doing chips once past the intial time to read up, and get the
equipment
	isn't that hard, and for cuustom stuff you can get your investment
back 
	quickly.  Plus your not always waiting for the mailman.
	Really on something like that/this  getting the car to someone with
a 
	diacom, and doing a custom chip would be the only really right way

	Also, it will never be 100% right.  What you have outflow the MAF by
a large 
	margin so WOT is going to be a compromise.

	Where is Clarksville?.  Is that where the shop is?....
	I might be of some help inna week or so..

	As a new subscriber to the list I just wanted to pop in and say
hello to
	>everyone. I own a corvette restoration and performance shop, and I
am always
	>looking for a better way to do something. My current project car is
a Paxton
	>supercharged, stuffed to the gills 355, 1989 Corvette L-98 engine,
with 30
	>lb/hr injectors, and a fairly radical cam, with estimated HP in the
range of
	>600-650 BHP.  The stock computer with a privatly burned chip in it
is
	>working really well (esp. since most everyone said it could not do
it.)
	>Anyway, the only small problems I am having with it, is it is
idling
	>(hunting) between 5-700 rpm, and I need to get the idle up to about
850,
	>with this lopy cam I designed for the engine. The other problem is
with the
	>built in rev limiter, keeping the rpm under 5400, and this needs to
be
	>raised to approx, 6400 rpms
	>So, who's got what suggestions, and who's the most reasonable
person (that
	>knows what they are doing) to burn a new chip just like the one
currently in
	>it (i.e- they need to be able to "read" the chip that is in there
now), and
	>then make these two corrections to the programming?
	>Any ideas or suggestions? Someone in the general Louisville, KY
(say within
	>200 miles), would be a big PLUS!
