Wagner Evo 1 vs. VRSF 7" FMIC

[martymil]

The problem with bar and plate is the ic's once heat soaked it takes forever to cool them down

Tube and fin on the other hand recovers quite quickly

[elburbs]

OP which one did you end up getting and why?

Cheers

I think this is more marketing then anything else what they don't tell you is the bar and plate will also take longer to heat up (a good thing). I can do a 1st, 2nd gear pull to redline and temps go up by 3-4 degrees with my wanger evo 1 perf.

no issues with taking time for the intercooler to cool on track. with ambient temps in the mid to low 30s 3rd 4th gear to redline on the straight sees temps go up to high 50s, by the time I'm braking for turn 2 temps are back down to mid 40s. was the same lap after lap with no real evidence of it getting heatsoaked and temps creeping up.

overall very happy with the intercooler definitely recommend it . don't see the need to butcher the car if you're staying on stock turbos.

im using the vrsf 7.5'' race fmic and a 30-155 limiter pull my iat dropped 3* from starting temps. haha started at 89* ended at 86* 155mph. ambient was in the lower 60's. no meth for iat cooling thats all intercooler

That's not marketing hype that's what I encountered drag racing and on the track

Where the bar and plate would be consistently 10 to 15f higher than tube and fin

The weight saving is substantial too and for a few hundred dollars more it's worth it

agree if you're racing competitively tube and fin is worth it for the weight saving alone.

Do any of you have logs or feedback on WGDC when switching to the Wagner/PWR (Tube/Fin ICs).

Vince... are you referring to mine?? Well I was the only N55 & VRSF FMIC !!

Ah right, I remembered it went from 250ish to 230ish but actually only ended up being a 13kW difference.

But still from comparison my Wagner Evo 1 went from 266kw to 259kw over the 3 runs, with turbos with a lot more boost and less efficiency. I guess not directly comparable without seeing IATs though.

You only made 266 kw with IC, downpipes and MHD 2+? Shouldn't those mods on an N54 be pushing close to 300 kw?

300kw on 98 would have to be a very inflated number.

Dyno numbers aren't comparable between different manufacturers. Even across different shops with the same dyno manufacturer have large discrepancies.

This was done on a Mainline dyno which tended to read a lower than other dynos. For reference, my car actually made the highest number on stock turbos on 98 fuel at 266kw, and a Pure Stage 2 on 98 made 307kw

[Alpha Trion]

for reference, i am on 260kw atw with basic bolt ons (intake exhaust and jb4) with my n54 (dynoed at Advan).

Still reading this thread to help me decide on cooler

Yeah I understand that there are often some pretty large discrepancies between dynos. 266 just seems to be on the lower end of what most people with FBO seem to post. General consensus seems to be that 400 WHP is pretty much par from what I've read.

hey, sorry, slightly off topic but whats your experience with running stage 2 without the ic? was it reliable? would you suggest for it or against it?

thanks

I wouldn't suggest raising your boost without a larger intercooler.

Wheres the cheapest place to get the vrsf?

I have also tested the ER competition fmic and the newest Wagner competition evo 2 both are good but both always had IAT's climb 15*+ over starting temps by the end of a single fourth gear pull using my pure stage 2 hybrid. So far the vrsf has more then exceeded my expectations, my only gripe is its heavy!

The 7.5" Race is an awesome cooler for the money. I was super impressed with the IAT suppression it offered upon initial testing in a hot dyno room running 25psi on upgraded turbos, the only downside is yes it's heavy as fuck, lol.

The 7" HD uses the same high density core as the Race albeit with a much smaller volume core.

From my experience having datalogged many many cars on the dyno where airflow is limited and coolers will heatsoak quickly (resulting in drastically rising IAT's) the 7" HD out performs the Wagner Evo 2 Competition and the 7.5" Race is even better again. There is only one cooler that out performs the 7.5" Race but that's crazy expensive so I won't bring that into the conversation, as the Race cooler is all the very large majority will ever need providing they are not fussed by the weight it adds to the vehicle.

The important number to consider when comparing one dyno to the next is what does a completely stock N54 AT/MT vehicle make on THAT particular dyno. No two N54 AT vehicles will be identical but they will generally be within 10rwkW of each other providing both engines are healthy and there are no underlying mechanical issues.

Once you know the approximate baseline # of a N54 AT/MT vehicle on that dyno you can calculate the all important Delta achieved between stock and modded and that should allow for a reasonable comparison between different cars on different dynos, providing you also know the baseline # of the other dynos.

Not the cheapest all year round but I have a large inventory of parts in stock and I'm more than happy to negotiate bigger discounts on bundled purchases.

Cheers,

As a reference my 1M made 262rwkw FBO (Wagner Evo 2) with stock mid and rear section. Running a custom 98 Cobb tune. This run was on a hot and humid Brisbane day.

I’m now running catless 3” straght pipes. Do you guys reckon it’d be making more power with the full xorst?
