I know a lot of blowers make them run like that....I have been to many tractor pulls and they all seem to idle like that.. My guess is that they are running a lot of fuel as to not melt down the pistons.. I would check with guys that deal with superchargers and see if they know why.. You could always tone the charge down by changing the pulleys and running lower boost...There aren't to many people running blowers on the street not like that anyway...Bill

Yes Raffa. I do know of the car.
That articulations is caused by ether the cam profile or the barrel valve adjustment. That's power baby!!!!!! |

That is a nice car, but what you are experiencing is blower surge. As Bob stated, it can be tuned out to a large degree, but as it was in the video it is excessive in my opinion. You need someone that knows blowers to change the pills and tune the system. It will be a lot more streetable with a proper tune. As it is now, it's really only good for full throttle applications. Does it calm down when it warms up?

Raffa
I have "heard" blower car racers say this is a lean fuel setup condition to keep the idle down while still being able to hold the car (stage) with a tight converter in gear on the brakes, as they do not wish to loosen their converters for their race applications. The engine idle hunting is the engine looking for more fuel. Put a stick in it whoohoo !!! Cheers Peter |
I agree with the convertor being to tight..

from "The Blower Shop"
This is caused by a rich/lean cycle at idle. As the motor leans out the RPM's increase and richen up the motor, when the motor richens the RPM's decrease and the motor leans out again. This continual cycle is known as "blower surge". With proper tuning, some of this surging should be able to be eliminated

Try turning the idle up and see if that makes it better???
Sometimes that's all it takes... |
Yes .. Think the cause is the idle mixture ... If i pu the idle at 2000 rpm ... No surge ,,,
|
Maybe you should look at the date of the post... I just don't get it.. Why people reply to old posts... Some as much as 3 years old...:slap: This one is over 4 months old..............
|
Cause we only chat here once in a while..... Raffa is a busy busy guy.... He does awesome work over there in Italy..... :)

Toretto's car is a nice build you guys are doing... :)
I think the car will MPH good out on the Big End of the track.... But with the 3.73 rear gear, I think it's going to be hard to get the big girl to move to the 60' mark... But if he is going to do allot of street driving? that gear is a nice one.... Just my 2 cent Keep us posted... :) |
