    Just put mine on the dyno this afternoon. N/A TBI V6, and it made 210rwhp and 218rwtq. HP was still going up at 6000 where the graph cuts off. AFR still seems a little lean, so hopefully I can correct that and pick up a few more ponies.

    dang, i would of swore you were closer to about 300 at the crank
    assuming an 18% drivetrain loss your at roughly 260 hp

    guess my numbers arent gonna be as high, oh well thats what a 150 shot is for

    I thought 18% was for standards? Mine's a 700R4

    I did some looking around, and it seems to vary widely, so I'm not gonna bother trying to guess crank HP at this point. It's kinda moot anyway, since rwhp is what moves the car, not crank.

    17% roughly for a standard and 21% for and automatic.
    The parts that are available for the 4.3 off the shelf the majority can get and or afford only allow around 225ish. It takes lots of money to go beyond 225 which has never been attempted by someone from a board. It takes over 11:1 compression, stroking and other things to break this barrier in NA form.
    As far as dynos, you can throw them out alltogether. Each dyno type measures in a different manor, tires and gear sets effect readings and so fourth. Dyno's are only used to measure gains when base runs have been done!

    im gonn have to call bs on this, a guy on another forum im on ran a 14.7 on a low compression motor with no boost (broken supercharger)

    so he is putting down roughly 228 crank hp on an 8.5:1 cr

    14.7 is not hard to achieve using a regular cab thats has proper traction. If its a extended cab, it's all lies like most of the boards are and have been since 1998 when I first joined them.
    There have been alot of talkers/dreamers on the boards since their inception, but 225 is all the injectors from the CPI motors till current can muster. 19lbs and hour wont support more and only currently with forced air and FMU's can that number be raised to 23.1lbs and hour supporting 260ish.
    Someone may crack the barrier with the 2114 intake and larger injectors if they can nail the tune down, but that yet hasnt been done either.
    NA you got a high 14 to low 15 truck and thats the best its gonna see until someone does something other than add a cam and exhaust!!! Sorry, but facts are facts and tales will always be tales which alot life by as truth!!

    14.7 is damn impressive on a low compression motor

    and by the way the cpi motor was discontinued in 1995, and the new csfi motors run a different injector then the cpi motor

    there is a guy on s10 forum who ran a 14.8 on a stock motor with a y pipe and cia, so thats roughly 220 hp

    your theories seem to have lots of holes, in your first post your talking about off the shelf parts, and now your talking about what the stock fuel injectors max out at

    what about people running carbs or off the shelf mpfi manifolds?

    he did that on TBI injection

    have a nice day :D

    14.7 is not impressive as you seem to make it out that it is.
    Regular cabs can run low 15's right from the factory.
    I know personally a SSF member that has a extended cab Xtreme that was a pure stock that outran his buddies modified extended cab Xtreme of the same year with a 15.6 to a 16.1. That truck with a cam added, exhaust and some other minor work to achieve 225 would then run 15.1. Drop the 800lbs that the extended cab runs and what do you have???

    Sorry but Ive read all the combos run on the forums in NA trim and thats as quick as they run. TBI, CPI and CSEFI all use the same amount of fuel delivery, 119.1 lbs and hour. TBI's do it with 2 injectors, CPI batch fires the same 6 as the later CSEFI do independently. The drawback on the pre96 motors is heads that puke out at 148 CFM and worked maybe 190 CFM which the 96 and later flow over 220 CFM. No matter how the combo is built the cap is layed out and maintained by the fuel it can deliver. If someone upped the compression ratio, matched it with and intake that would flow the numbers with heads that also could flow you'd see the numbers increase closer to 275 with 24lb and hour injectors or 144 lbs and hour total.
    No ones ever done that yet on the forums. Only forced in some form has the 275 area been hit and that leads to low 14's and high 13's.

    The numbers will always add up and when someone goes beyond what the numbers truly support you know you have a lie that has formed itself. High 14's are achievable with a regular cab and decent traction and gears, 15's on the low end for extended cabs and high 15's for Blazers.
