Very nice!

I also noticed VRSF improved their website recently which is great! Their old website imo was really difficult to navigate and search for stuff.

Do you know the main difference with the performance hd one and the weight ?

I read about the Swedish do88 FMIC and, if I understand the text correctly, it has an increase in pressure of 18 %.

My noob question is then if this would eliminate any risk of increased turbo lag even on a stock car?

Do88 claim that the pressure drop characteristics mean that it will flow better than stock and make no difference to lag.

I'm no expert, but to my mind, with the volume increase on the do88 being large ( its a well engineered bit of kit) the turbo is going to have to push alot more air to get up to pressure, so personally I can't see how it won't introduce lag on a stock car - I would expect a tune was needed.

But I do agree any 5" intercooler isn't worth it.
I bought and installed the Wagner Competition 1 with ER downpipe from Mike...great price and customer service. I use the car mostly for track, road courses , and my Awron gauge kept posting insane IAT numbers as the laps and temps increased. I just spent 2 days at Road Atlanta in 95+ degree heat and I am very pleased with this upgrade. I ran virtually the same times all day regardless of temperatures. Don't get me wrong, the IAT were way over ambient air but much better than stock and quicker to cool down. The key for me was the easy fit, no turbo lag and improved performance. I know there are bigger models, but the risk of lag was more important that the hypothetical gain on a non FBO car.

Why is the VRSF intercooler so much cheaper than the others? It seems to have good reviews. Why would I want the Wagner EVO 2 Competition or Active Auto Works FMIC instead?

Would Wagner Competition 1 be overkill for a stock-tune daily driver that does 1-2 track days a year? The most I would go mod-wise is a catted DP so not sure if the VRSF 5" HD is enough. I feel CSF would be too big for my needs.

The simplest answer is the fact that we don't include an M-tax on our products. We offer a 5" Performance FMIC, a 6.5" Competition FMIC along with the best performing 6.5" Race FMIC which can support anywhere from 800 to 1000 WHP.

The benefit of offering 3 different intercoolers for this platform means you don't have to compromise by going too big or too small. We offer a solution for every customer

The VRSF 5" Stepped HD will outperform the Wagner Comp 1 and is generally recommended for customers interested in sticking with the OEM turbo. If you're looking to upgrade your turbo in the future, our 6.5" Competition will outperform any of the comparably sized options at a fraction of the price.

Wagner EVO I and VRSF 5" HD are both great options for a stage 1 application

As a N55 owner who struggles with high IAT's on the track - can you please elaborate on what you mean by best performing? Do you have anything that shows what kind of improvement one can expect with your intercoolers? I'm not trying to be a smart ass here - it would be great to be able to see what kind of advantage your coolers offer. Quickly getting over 160* IATs on the track sucks. I already have one of your competitor's IC & it is being overwhelmed pretty quickly. We are trying something else but if that doesn't help I am working on the backup plan. Trying to limit the replacing of parts that I just purchased/installed - again

Mike, thanks.. when you say Wagner EVO 1 is good for stage 1 applications, are you talking about the performance or competition or either? I do like that the EVO 1 competition is lighter than the other options out there.

Both, are good for stage 1
competition is the better option always. the main difference is weight and recovery time

Has anyone had any experience with the Inter cooler from Tuner Motorsports?

Looks pretty decent and they have some first hand experience with racing BMW's...

Some initial logs on track with complete stock compared to do88 FMIC/water/oil coolers. No tuning. Slightly different types of track AND a (visible) cut out pause in the middle of the logged session with the upgraded cooling. I will log on the exact same track on monday!

Interesting logs.

Please can you let me know the responsiveness of the car with the do88 FMIC? Is there any noticeable increase in turbo lag, or is it actually more responsive?

Did you change the charge pipe also?

Thanks.

No charge pipe or other changes to the car at all.

I haven't felt any differences in response or anything. That doesn't mean there could be some differences but I haven't been able to feel any so if there is it must be very small.

Cheers.

I definitely recommend doing the charge pipe - it'll give you insurance against a blow out/cracked pipe and also improve the air flow. I wasn't expecting anything, but noticed improved throttle response from the charge pipe alone.

I did try do88 charge pipe, but theyve had a batch of charge pipes released with too much paint on the throttle body end internal surface - I could not get it to go on at all - now with another brand (forge),although I wish the do88 had fitted as I could see it was going to be slightly better for max air flow.
