Has Anybody Fitted the Wagner Evo 1 Intercooler?

[javbomb]

Hey all,

Curious if anybody has fitted the Evo 1 yet?

http://www.wagner-tuning.com/product...200001107.html

Looks to be a nice sweet spot for those only seeking maybe 600 crank hp max from these cars, and possibly not have to change crash bars etc, keeping the cars factory integrity there... For us overseas folk, pretty much any intercooler we choose other than this one requires a US crash bar purchase with it, which is super expensive when you combine them. This is a very affordable option otherwise.

Also seems to be small enough with 57% volume increase that there will be zero mid range hit on power that some of the larger coolers experience and pressure drop is better than stock.

Stock Intercooler seems to be 8.3l volume. Wagner Evo 1 is 13.07l volume, and Evo 3 is 16.5l volume.

The APR Core is 14.7l it looks like which is about 77% more than stock. Cant find volume numbers on Iroz or STM.

I just wish they tested it in a reasonable ambient temp! 4C is useless information to me.

Would love to hear any real world feedback. Was the install painless, any crash bar mods needed? Even better some Dyno numbers of stock vs this one. A lot of other intercoolers are seeing up to 20-30hp increase.

More importantly in reasonable temps >20C are you seeing heatsoak with something like a stage 1 or Stage 2 car. I dont care about drag racing, I just want to absolutely avoid any heat soak on the streets and protect the engine when I eventually have a stage 2 500+ crank HP tune and mods.

Hi
Thanks for sharing this.

I did not know Wagner had this type of intercooler. Looks like this will be the intercooler I will go for unless Unitronic comes up with something better.
The EVO 1 looks like the IC from ABT (the whole core is exposed to air flow) except for the price is much more likable :)
If you compare the data log with the larger EVO 3 you will see that they are pretty equal when it comes to cooling. EVO 3 is a bit better but you will have to remove your crash bar to fit it.
Both the data logs for EVO 1 and EVO 3 is probably first pull logs to get better data / cooling result so it would be interesting to see the result after 10-20 hard pulls. This is probably also where you will see the EVO 3 can handle the heat soak better.

It's Tube and Fin, rather than bar and plate. I'll be waiting for Unitronic. I can't see Unitronic producing anything that is not bad and plate and not more effective than the Wagner!

[OE2]

FYI STM uses a garrett 3.8in core and Iroz has both the 3.8in and 3.5in garrett cores for their RS3 intercoolers. you should be able to get garrett volumes from their site.

^^ yes but Iroz's intercooler price is obscene. I am not saying that is it not a good product, it performs well and it fits well but the pricing is too high. I am aware that people buy them left and right and is a good selling intercooler but it is appealing to people that don't care to pay for an overpriced intercooler. $1600 for an intercooler is nut!! On another token their downpipes in my opinion is the best priced and best looking in the market, that is the irony.

[shivaswrath]

...isn't APR bar and plate and cheaper?

For you US guys maybe but for anybody with ROW cars we actually have to buy your US crash bar to fit anything (and stay legal) which is where overall price skyrockets...

Hence the dilemma.

If I wrote this, oh boy I would get ass raped here.

Isn't everything he sells pretty pricey? DP and Midpipe are catless, non resonated, and not really the best design, so it is not cheap for just piping. Plus, he shoulda made the pipe by turbo flange a large cast 90° elbo, instead of a big space taking loop that is heat emitting piping, vs cast elbo to run the pipe down/out fast, so their would be less heat in the engine area, cuz the first three feet of pipping are the hottest.

It's also utilizes cheap looking cast end tanks, unknown core made in China. I can't see putting that on my $60k car personally. But that's why we're lucky to have options.

Stm's seems like the best balance of value and quality, currently available.

[OE2]

cast end tanks look less fancy but as long as they hold the pressure you're looking for (most are pressure tested to 50psi) then they are a winner in terms of price to the consumer.

bar/plate tube/fin debate http://www.superstreetonline.com/how...p-intercooler/

I haven't seen a clean comparison between garrett cores and, say, vibrant cores to see which is more efficient and why but the closest i saw was on evom.net with ETS 3.5 core vs 3.8 garrett cores (not a fair comparison)

Iroz has billet end tanks that have vanes in them and use the 800hp garrett core ($1600). STM uses the 1000hp 3.8in garrett core and shows a pretty significant drop in mid range HP on the stock tune. APR, IROZ and CTS do not show this drop mainly because their core's aren't as large.

[context.eax]

Tube and fin. Bar and plate? Please explain. And please no because they said so. I want science.

Here is a video explaining some of it:


Some info I found:

Tube and Fin - Pros
Generally weighs about half as much as a bar and plate core of similar dimensions
Generally less expensive
Generally less flow restriction within the core than bar and plate designs
Less flow restriction through the exterior allowing better flow to the rear of the core and to a radiator, AC condenser, tranny or oil cooler, etc. which may be behind it

Cons -
Those with less flow restriction than bar and plate cores offer less heat rejection
Generally have more fins which means they're more likely to be damaged by rocks/debris which cuts down on cooling efficiency
Charge air entry extends beyond core wall making it more difficult for air to enter the core cleanly


Bar and Plate - Pros
Generally off greater heat rejection than tube and fin design
Those with turbulators offer even greater heat rejection
Offered in tons of varying shapes and sizes
Less likely to be damaged by rocks and debris
Charge air entry sits flush with core allowing for cleaner entry

Cons -
Weighs about twice as much as a similarly size tube and fin core
More expensive
Blocks more airflow to radiators, etc. which may be behind it
Those with turbulators have greater flow resistance to the charge air
(source: Bar and Plate vs. Tube and Fin)


More info
Bar and plate cores are good if you do short power bursts, they have more aluminium (weigh more) so they are a better heat soak. But they take longer to cool down. Hence good for drag cars and road cars that get short burst of power then cruise. They do limit the airflow to the radiator more than tube and fin cores.

Tube and fin cores are good for more constant power applications, they weigh less so not as good for instantaneous heat soak. But they shed heat quicker than a bar and plate. Hence good for circuit race cars and cars that see long periods of sustained power.
(source: Tube & Fin Vs Bar & Plate)

With some math: bar & plate VS tube & fin

So I guess you cant get "The Intercooler" for your car but have to choose one for your usage. Some is better on the track, some on the drag stripe etc.
But I would assume that Wanger is making a great product here and I like that the coolers is not that heavy when placed up front where you definitely don't want the extra weight.
Also the Wagners whole core is exposed to airflow where other brands have like the upper 1/3 of the core behind the crash bar with less to non airflow.

Perhaps someone else could chime in and explain a bit more regarding this subject?

Depends what you're into. Fit and finish is important to me. If you can get past that, then it's a good product I'm sure.

[OE2]

“Fit” is a perfect match for iroz and apr. “finish”... well only you will know what your endtanks look like after your bumper is reinstalled.

I plan on going with the BCS DP ... Looks nice. 100cel cat too and heat wrapped.

[javbomb]

Interesting posts here guys. Thanks for weighing in.

I think I'm going to take the plunge for the team and grab this EVO1 intercooler sometime before year's end.

My car is not going to ever see more than 600 crank hp max or so. I really don't want any mid range sag at all due to a bigger intercooler. And I don't want to pay to replace the existing crash bar. Sounds like for the street this should do fine, and I don't need a core rated for 800+ hp.

It's interesting the Apr one is only 1lt more volume than this Wagner Evo 1. I was initially thinking the difference would be much higher.

Will get my car on a dyno and see how much power it adds and also when it heat soaks if at all after 3 or 4 back to back runs.

Thanks for all this. Very interesting. And I thought it was going to be easy buying an intercooler. I’m also leaning to the ev1.

Since it has a cat though, it looks like a good price to me..

In Australia the Iroz DP is $1800 AUD. I can get this BCS System landed for about $2200.

I definitely think I need a catted DP.

Although I think Unitronic is coming out with a catted DP soonish. May wait and see.

[RRS-33E]

Can someone tell me if the Wagner IC Evo1 will require a tune file? Or will it throw up a code error with stock tune?

[NelsDMAX]

No tune file req’d, stock file ok

The thing about the STM IC that I think is not ideal in performance, it its width. Wider may not be better for flow and efficiency.

Ended up buying CTS ;)

Did you install it yet?
If so then did it fit without trimming the crash bar or recalibrate the acc?

I ordered the US crash bar...

Ended up getting the CTS so cheap on black Friday I thought it was worth it..

Will be fitting this Friday, dont anticipate any issues at all with fitment since I have the US Crash Bar, the Foam Piece, and the US ACC bracket.

I also dont think I will need to calibrate. At least, I am not planning on it.

Ok I see :)
Can you tell the difference between the us and the row crash bar?
If you can share any picture when you have them both removed from the car than that would be great.

Not my pics, but the US one is further forward, thus more room behind it.

That ic looks so beastly, love the integrated crash bar. How do you like it? Did you notice any improvements? Any lag for such a large ic? I'm really interested in purchasing one of these.

So this obviously doesn't work for those with ACC right?

bumping thread, but an integrated crash bar can't have the same support as a standalone bar?

[jjoyce831]

I've got an EVO3 coming in from Germany. Guy sold it for $700, couldn't pass it up. It looks solid, but it probably does remove some of that safety in front end collision. But race car, right?
