ProMeth or Inter-Chiller

I’ve been weighing the pros and cons of methanol vs inter-chiller. The intent of my build is to provide reliable and simple daily 650-700 whp. Would like to keep IAT2’s consistent while running pump gas, with an occasional mixture of VP 110 or 113 (much more readily available to me at this time than E85). Really want to stay away from ethanol due to availability and initial costs.

I’m currently at 540 ish with 2.55 upper pulley, 2” headers, iD850, Airaid, Fluidyne HX, NGK 7, reinforced brick, Pierberg 150, DMS under hood tank.

Next round of mods will include 2.4 upper/8.6 lower, DSX billet lid (with ZL1 ProMeth plumbed in), ported LSA heads, ported blower and snout, 103 tb, cam TBD.

I’ve been waiting a month now since I ordered the ProMeth set up and am getting no response from them regarding status. Curios if they are even still in business and may possibly cancel the order and put $ towards Killer Chiller. If they respond soon will probably keep the order open and install anyway. Cons to consider would be potential failure of pump or controller.

I’ve been seeing good things about inter-chillers and the simplicity of the design. I understand that I may need to replace the Fluidyne HX for clearance and replace with stock, or even bypass HX altogether. The cost of the Killer Chiller is comparable to the ProMeth set up was not looking forward to storing and refilling with meth every month or so.

I am leaning toward E as a last resort because availability is very scarce up here in the PNW and initial costs could be spent alternately. I do have access to VP 110-113 and may use a mixture to up octane as needed. Methanol was initially selected as it seemed to be an easier and more economical approach to gaining bump in octane than ethanol.

In summary I would appreciate if anyone has any suggestions or recommendations for either and am not opposed to running both. Pros and Cons of either would be highly considered and appreciated.

Thanks in advance
