I just cheked in and realized there has not been a post on the crate tech tab for over 2 months

what has happened to our chat boards???

if it sounds like it's on a chip at 6000 but there is no chip ---the high speed air bleeds are too small
If you are trying to run it over 6200 you might need valve springs

you can call me...

I currently only have one O2 sensor in each collector and the unbalance that I see in that is disturbing
I have an associate in Canada that runs 10 O2's and he is guiding me into this process
He...

I hear you on the stale part
actually thats why I started this thread a while back just to spark up some conversation for those of us that are not facebook junkies

as for me ---I live in the...

the spacer rings move the torque number around a bit
really it's nothing game changing (on a crate)
my opinion is the correct height to gather cool air while not too high to decrease downforce or...

unfortunately when a crate actually "blows up"--there is usually nothing but a set of valve covers and maybe an intake manifold
when a piston fails (and that is usually what goes first) it goes off...

with prices of everything we touch escilating on a daily basis will racing come to a point that we say its time to cancel the season?

it's a sad time in the world right now and it is very hard to...

when i started in the crate world i certainly had to change my standards for out of round
crates cannot be bored or use any type of over-size piston or ring
it was (and still is) amazing to me how...

the 1.590 I would think signifies venturi size
and 1.590 would be a monster carb for a big cube engine (not crate at all)
measure the base plate bores---I bet they are 1 3/4 minimum maybe bigger
...

this recent change by IMCA will have plenty of your competitors lacking performance and flirting with engine failure on race day---you are ahead of the game by researching the topic before changing...

Great topic Zero
what we have found in the 400HP world of crates is that it really doesn't add up to a hill of beans either way

we do like rear pumps for keeping the heat from the fluids
chassis...

I hate FB but I love conversation so I am gonna change it up a bit here so we can spark some conversation

AERO--in crates

I am an old guy and 30 years ago aero stuff was only for looks but in...

Good to see your still involved John---

E85 has been the trend across the country for a couple of years--so RUSH going to it is no surprise
carburetorts are able to be converted (proffessionaly)...

zero--
back up a post
colder fuel--colder air always makes more power----cold shrinks everything ---this enables you to get more into the same space creating a bigger explosion in the...

absolutely----

I have seen quite a bit of engines angled down in the back as well as to the left
when these cars get up on the bars and pinned over on the RF ----the carburetor is not happy...

here are some casual results from testing
but at the end of the day --I promise you cooler fuel makes more power

during the winter months we store our bulk fuel in an unheated garage
IF we run...

Dirtslinger,
When you say you gained HP and TQ with the 1” SS --where were you looking in the curve?
I’m sure you did pick-up some HP above 5000
And your peak TQ number climbed above the shorter...

an actual fuel cool can is considered illegal in many crate venues ---HOWEVER---let us look at the subject of "cool fuel"
in the gas family of fuels, the cooler the fuel the better the performance...

I am definitely not a fan of oil additives
here is a video from one our associates that addresses additives

here is my 2 cents on the Mobil 1

when we started this crate stuff back many moons ago---the sticker on the oil pan said to use 15/50 mobil 1
this engine concept was all new to us so we...

very sorry to see no new posts in over a month
FB is taking over without a doubt and that is sad

I am guilty of not checking in but we have been absolutely slammed with work and testing

how...

several years ago I was at a 100 lap superlate race in WV that bloomquist was in.
at the half way point as he was lapping most of the field his car erupted in steam
a couple laps later there was a...

on 604's we stay away from true 750's except on methanol
we do use a 725 for E-85
now that is our opinion ----many people run 750's on gas successfully ---it's just not the way we approach our...

750 carbs on gas do not accelerate as well as a 650
the 750 will make more power past the flagstand but the 650 will get to the flagstand quicker.
We prefer 650 carbs on our 604 packages when using...

first of all put the carburetor back the way it was when you purchased it---
it's always a good idea to check passages in a production built unit but you shouldn't need to start changing...
