i have heard rumors of stroked vq's having problems with over heating.........any truth in that?

 

mainly because they've ran really huge intercoolers blocking flow to the radiator

all sleeved engines overheat more. There's less surface area for coolant to flow across

you can get massive fans for the coolant though which I think has mostly solved overheating

 

Oh ic... if this is the case then the guy at Haltech gave me the wrong info. He did say to talk to this other guy for complete, who was out of the office that day, but I guess he wasn't very sure.

Cool, so the software is an all-new version of HalWin? Not the 1.171? That'd be great! Good to see more options... Regardless, I'd be hesitant to let my Fcon go, since it works so well, but we'll see.

 

anxiously awaiting the Haltech, not a fan of EM's that I can't have access to for tuning....

 

The IC thing is true, but I really do not think that it's the major factor.

It's really the sleeves, when you have a a sleeve of one material inserted into a block made of another, the heat transfer between them is not going to be as efficient as it was through a single solid piece of aluminum. You can say that the iron insert in the stock block is still steel and not aluminum...Well, this is true except that it's inserted and cast over, so that hte heat transfer between them is very efficient, and more over the part that's cast over the steel inserts is connected to the rest of the block since it's all one monolith,,,so the heat from the sleeves is dissipated to the rest of the block, effectively extending the water jacket surface that's removing the heat.

My car for example has a 5" thick FMIC that "blocks" the airflow to the radiator more so than the APS Extreme 5" FMIC (since it extends down lower than the APS FMIC) ...but after installation of this FMIC I had MAYBE a 0.5-1 degrees C increase in coolant temps at cruise (relative to before) at identical ambeint temps.

But we really don't have an alternative... The Darton sleeves are the only ones to do, period, as the track record with AEBS sleeves is so horrible that make it essentially unacceptable. The reverse is true for Dartons...so that's the only name ofthe game.

One can always do the milder GTM 3.8L HiRev drop-in stroker that doesn't require sleeves. That's the ticket IMHO.... Or, just do big cooling fans to alleviate the problem... It's really not that hard to deal with it.

 

^^Correct^^and the alternative is not running sleeves, especially for cars that see road course/track time. Sleeves are designed simply to contain massive amounts of pressure, and strengthen the block for quick bursts of power, such as 1/4 mile racing, where cooling is not an priority. Nobody that builds endurance engines for circuit racing uses sleeves. This is the main reason my engine runs pretty darn hot at the track. I'll be switching to an unsleeved road racing block shortly.

 

Yes, he must have given you wrong information. They should have referred you to us, but that is beside the point The software is all-new, not 1.171 or a revision of that. I am not even sure we will use the HalWin name for it. It is really slick, I will have screen shots up before too long.

 

Nicceeeeee... gthe software was a major complaint point for me with HalWin... it's good to know that they finally revised it...perhaps HalIP 2.0!

 

Funny you say that, we have already had people confused with the Hal / Haltech relationship haha... coincidence people, coincidence

 

Hal actually begged them to change it to "HalWins".

 

when can we expect to be able to have a haltech unit in our hot little hands?

Thx

man, every EMS that's about to be release is always the best thing out there. I mean, the emanage ultimate and utec were hailed as the best option to buy for an EMS.....until people found their shortcomings.

 

Neither of those was QA'd on a 1000whp Z.

 

There is always something better around the corner.....it's better for everyone in the end. That Haltech is looking very very promising.

 

Thats a pretty bold statement homie. i would assume you run the 3000 dollar f-con v-pro. you see as technology advances, there's always gonna be something bigger and better coming down the pipe. as far as i'm concerned, my setup, with its 'shortcomings' worked great at 440whp and will work great at 600whp. now if i were going stroker, 1000cc injectors, and bigger turbos, maybe i might plunk down the cash for a more 'sophisticated' setup. my .02

 

yeah I have an Fcon V pro, I also had an emanage ultimate POS that fried my coils, could barely start my car, and wouldn't work with my HKS ignition. I remember when the UTEC was coming out, people were acting like it was going to be the "sonic boom on the Z community for EMS's" and it's not bad, but it has its own issues too

Bold statement? maybe, but it's still true. The big hype comes first, the the flaws come 2nd

Yeah there's always something better coming out, but people don't seem to realize just how much hype each new product has with people buying them completely untested and end up with flawed and buggy products or where there's othere issues that are later discovered. I guess it's the same for any early adoption of anything for the people willing to pay full price
