Title: High Flow heater boxes? Post by: andrewlandon67 on March 30, 2016, 04:46:47 am Who on here has experience running any of the larger diameter heater boxes? I'm considering stepping up from stock on my medium-level 1914, and really want to know who makes the best ones. For a reference, I'm running 40x35.5 044's, 120 cam, 1.25 rockers, 9.5:1 compression, and Empi 44 HPMX carbs. I'd also prefer to stay away from sidewinder-style headers, they don't bolt up to my glasspack very well...

I don't remember) big bore heater boxes back in 2007 or so, the finish was pretty rough on the flanges, lots of casting flash/welding glob/whatever, they needed some work to get the whole 1.5 inch diameter usable.

Title: Re: High Flow heater boxes? Post by: Martin S. on March 30, 2016, 19:42:43 pm cip1 sells a selection of different size CSP heater boxes for a reasonable price. They aren't stainless so maybe there is another line of stainless models in the different sizes?

Post by: andrewlandon67 on March 31, 2016, 04:39:39 am Those CIP ones look pretty awesome, but I'll probably have to save up a bit... I'm assuming that they have all of the fins inside like stock, right?

I'm assuming that they have all of the fins inside like stock, right? No, none of them do. I've yet to try them for myself but I've repeatedly heard that they are not very effective. Maybe those and some seat heaters will get you by if your winter isn't too harsh. Title: Re: High Flow heater boxes? Post by: alex d on March 31, 2016, 16:40:03 pm Those were 95% certain JP Group.

JP Group that's what they were! Title: Re: High Flow heater boxes?

Colorado doesn't really do mild winter/spring... then again, this car is turning into less of a daily than it used to be. Title: Re: High Flow heater boxes?
