HPI EVOLVE RADIATOR 50mm core
 

Seems to be a lot of conflicting opinions between CSF and Mishi on here, wondering if anyone has this and how do you rate it?

RHDJapan : HPI Radiator Evolve & Radiator Rescue Set M/T - Z34 Fairlady Z

HPI dual pass 50mm core
CSF triple pass 30mm core
OEM 12mm core

words from the manufacturer:

"The radiator is engineered to regulate water temperatures and guard against overheating caused from extended hard driving, 2 core Radiator Evolve has a full aluminum wide-tube core with a cooling capacity over twice the capacity of Stock OEM. The radiator has a thickness of 50mm and is approximately 2kg lighter than the standard 3 core copper aftermarket radiator. The Radiator Rescue will allow you to realize the full potential of the radiator"

Yeah I still can't find any reviews or infor on its performance and reliability.

110,316 yen equals $972.59, plus shipping.

Yeah that core is expensive, I want to see if I can custom one built for cheaper.

When/If (LOL) I go boosted I will get the HPI unit. Guess we shall see how it does then.

Ron Davis, is the company that used to make the GTM heavy duty radiator. They will make a custom radiator for the Z but it is expensive if you get their twin fan setup. I called them and they want $1800 for the setup. It also requires a ac delete. Seb installed one in may and said is a quality product and it required quite a bit of fabrication to get it to fit on a NA Z. He was still waiting to hear from his customer on how well it is working for him at the track. The car is a dedicated track car for the most part.

For a "track only" car Griffin also has an option that was developed for the old IMSA and Grand AM cars if I remember correctly. Its keeping the AC thats a pain if you want a bigger rad, otherwise its pretty easy to get one these days.

A/C is a must.... LOL

Come on pal face, I didn't have ac in vehicle until 1985! Oh but it's a dry heat out here! :eek:

I live in central florida, Must have AC

If I can't resolve my high water temp issues, I will do an ac delete radiator upgrade as I don't drive my Z when it's plus 100 other than hard park events in town and if I need to go out of town I will toe it. I drive my truck during the summer.
