Would EVO intercooler create less lag over GT2 intercoolers?

 

Craig, sorry I just dont see how the Evo's are better. The pics you posted show the endtanks of both designs blocking the cores. Do we have any efficiency numbers from Evo? Kevin

 

I need to get with my buddy that builds intercoolers and play around with a few designs. An intercooler is an intercooler. It's a simple air2air design. Yet some are getting charged more then a Air2Water intercooler setup cost.

 

the flow/restriction issue is with the oem tube and fin cores with small air passages; with Blownsix or Evos they both use bar and plate cores which is all that is required for improvement.

the 15k rs tuning IC tanks and connectors looks much more similar to the Blownsix ICs rather than the Evos.

While we have the FBI/CIA involved in the investigation, we should have them check out the once $1.2k evo hoses too. Samco and Agency must be laundering $$ by selling so cheap....or maybe they don't flow as well too.

 

I have a set of the blown six intercoolers due to arrive later this week. I am doing so many other mods in conjunction with the B6's, I will never know if they alone make any kind of improvement that can be felt. However, I feel the design is fine for my purposes. I would argue the endtanks are shaped smoothly and are larger than the hose carrying the air to them, so they have to flow well - I don't see how they can be restrictive when they are larger in volume than the hose leading to them. With the larger core interior, the air should flow through very quickly and again on the other end, I think the biggest restriction is the hose again. Personally, I don't see anything wrong with them and felt they were a good value at approx. $1,700.00

 

Kevin, I don't even own the EVOMS ICs, so I certainly do not have efficiency numbers for them.

I have no dog in this race, so I really do not care. The EVOMS design strikes me as better, but I am far from an expert on the issue. I geuienely hope those who go with the Blownsix units are satisfied.

The core design is only one of the improvements possible from an after-market unit. The end tank design undeniably affects air flow.

I respectfully disagree. IMHO, the RS Tuning end tankslook far more similar to the EVOMS units than the OEM end tanks.

What does this have to do with ICs. I have never suggested that EVOMS's hoses are better than any other after-market hoses, nor attempted to justify the differences in cost.

Craig,
I believe (and thanks to you), the "investigation" is over.

Good luck.

With all due respect, how can this or any investigation be concluded as over with speculative comments from one board member and no hard data to back up any of the opinion offered? As a side note, I happen to agree that the B6 looks more like the 15K RS than the EVO...but again this is just opinion. The only way to know the differences here is to bench flow the three of them...and compare the data.

 

Evo is a sponsor..maybe they can chime in?

 

I don't think anyone that has chimed in here is an expert on B6's or anyone elses intercoolers. I would like to know, however, how RS arrives at their price.

Anyway, I am currently having a custom intercooler fabed for my 965 (protomotive) but for those of you that are interested in B6's I suggest you do a search on Rennlist. Lots of horror stories with B6. They claim their coolers are bolt on (so does EVOM). But they are far from it. Most require modification to the rear frame rails (996tt) or in some cases chopping apart the rear deck (965). That is why their are so many of these for sale on the aftermarket (new in box) because once they arrive they require alot more work to install than one would think. Most guys do not want to chop up their cars. Do your research.

As for price, you get what you pay for (except for RS, cause thats nuts)!!!

 

Anyone ever toyed with Air 2 Water intercooler, compared to a lot of these prices something like that could actually be feasable for those that are looking for a lot of horsepower and do not daily drive the cars. You can not get anymore effecient then a Air 2 Water intercooler.

 

One thing to consider with our intercooler design is the "hose over" design of connecting the boost hoses is far better in terms of flow and an air tight fit. When we were developing these intercooler and end tanks, a major improvement to the overall flow was this feature. We spent months on a sophisticated flow bench testing various different hand fabricated designs to test overall airflow and flow through the core. Once we found a design that we were satisfied with, the tank designs were programed into Solidworks, http://www.solidworks.com a sophisticated CAD program, where the tanks were refined. Additionally, solidworks allowed us to make changes to the design and realize the impact the changes made to flow on the computer. We then had rapid prototypes produced to finalize our flow bench testing as well as in car fit testing. Part of the reason that there was such a long time for us to get these produced and on the market was due to the over 18 month R&D process.

I hope this answers some of the questions.

 

We have done this before on a GT3 twin turbo conversion we just completed. They work perfect for this application, as the customer wanted a sleeper with no body modifications. Our liquid to air cores sit behind the rear wheels in the quarter/side bumper area. We fabricated a 2 gallon water tank and circulate the water through the OEM front center radiator with a bosch water pump. I will post photos in the AM.

 

I'd love to see how that was done! I am new to the Porsche world so I was not sure if it had ever been done. I like to think a little outside the box to make hp It's never failed me once
