Hey guys just finished a build..

302 .30 over pistons and rods 12:1 comp
gt40 p heads ported and polished by pan handle performance -new valves -springs
42lb injectors
gt40 lower intake
cobra upper
68mm throttle body
upper and lower pleanum spacer 7/8"
bbk cai
smog-ac delete
electric fan
set of 4:10's
slicks and skinnies
and suspension is being worked on at the moment havent decided on that yet
and dual centerforce clutch
B303 cam
i may be forgetting a few things but i belive those are the main modifications
ran a 12.6 stock with cam and slicks
dyno tune will be comming soon... any ideas?

[horsepowerjunkie]

Why such a big injector??

[VOGEL822]

for forced induction in the near future.

[fogged306]

You're going to boost a 12:1 engine? ... how did you come up with that figure anyway?

[VOGEL822]

its an all motor set up at the moment so lets talk about that

[95StangMX]

Well I am hoping you forgot to list a supercharger on there with 42lb injectors that is WAY too much injector, I am guessing its been tuned?

You have any flow charts on the heads? Hard to tell anything more than what stock gt40 heads would do without flow numbers I am guessing low to mid 12's

Just re read it and said tune coming soon so probably not going to run to great with those injectors until tuned, actually maybe worse than before depending how rich

[Smirnoff]

16's

[VOGEL822]

hey bud your a dick ^ i have the flow sheet somewhere

[VOGEL822]

ur a dick ^

[95StangMX]

Maybe I am a dick but you are going to get the same from anyone else that knows what they are talking about here, without flow numbers you cant tell shit about how it will perform other than stock gt40 setup, there are a lot of people that backyard port and polish shit and actually make shit worse than stock, and they usually provide no numbers, if your people provided you with flow numbers, then there is a chance they know what they are doing and did a good job, or they downloaded some flow charts of google Wasn't trying to bust your balls just trying to give you an honest answer, but I am sure a lot of people take me as a prick cause I tell it like it is

edit: I guess maybe you are talking about the 16 post

[VOGEL822]

yeah not u the 16 sec post lol your 100% right i was just looking for some similar builds the chart flow was perfect i forget the numbers on it ill have to find it

[VOGEL822]

pan handle pref do back yard shit yeah i know wa ya mean when ppl do shit them selvs sometimes terrible thing if they dont know what there doing or have proper equipment...

It's a simple question that has a simple answer. Part of why I asked how you came up with the figure of 12:1 is because some people just assume that because the piston manufacturer says it's a 12:1 piston, that that's the compression they have. That's not the case. Actual compression will have an effect on how fast your car will run. There's way too many variables left blank for anyone to give you any kind of an actual idea of what the car will run. Driver, suspension, other engine components are all missing variables (i.e. what rockers, whats the bobweight of the piston stack, what rings, what flywheel, what balance, flow numbers like 95stangMX mentioned, ect.) . Come back after the dyno tune and post up the sheet and the the weight of the car and you may have a fighting chance of getting a decent answer. Anyone that throws a number out there is just throwing a number.. like 16's lol.

your description of the motor build was too vague to give you a real number so i just threw one out there would you rather hear me say 10's. What pistons did you use, what rods did you use, valves bigger than stock 3 angle valve job what? and how did you get your 12.1 comp. ratio

[VOGEL822]

when i get more details ill throw them down

[HMERacing]

12.6

[flattusmaximus78]

Your motor doesn't have that compression and wouldn't start with those injectors.

[VOGEL822]

thanks HMEracing ^^^^ just looking for numbers here nothing else

[93hatch]

race gas?

[93mustank]

If its really 12 to 1 and running a b cam the thing will detonate all over itself on pump gas.
