Corksport turbo review

omg what is this etuning you speak of??? never heard of it in my life. how does one go about doing this? my etunes have never taken more than a month. thats a new turbo with 93 and e85 revisions.


beta testers should have had these on...fully tuned and ready to go before release to the masses in my opinion. how do you know what its going to do with no feedback? your going to buy something with 0 data out there? whats the point of being a beta tester if you didnt truly test the product?

maybe i expect too much. not knocking corksport. badass they put the leg work in for this. im sure its fine, but id want more info before i dropped my hard earned money.

This thread went from one beta tester's review, to yet another general turbo discussion. What a mess.

sorry for my part in the derail. ill hush. opinions still stand.

carry on

True enough. Probably could've released their results to grab our attention a few days prior to releasing completed beta results to back them up.

I'm thinking this turbo is going to come in slightly ahead of the BNR based on technology progression. The parts included also make it very attractive. That being said it seems that for all the R&D that must have gone into this, they rushed the release a little bit. Especially for this market.

This.

[bcmurphy87]

I feel like with this product release being so vehicle specific you HAVE to release some dyno and flow data. Your target market is speed owners looking for bolt-on simple swaps and the turbos only real market place competitor is the BNR S3. So if its my business im showing gains against both the K04 and BNR S3. Just saying seems a little rushed to the market IMO which is never a good thing.

[Easter Bunny]

50lb/hr puts it in competition with turbos larger than the s3. I think the whole true drop in bit is skewing people's expectations.

[Raider]

I do not want to go through and remove comments because of opinions and commentary that are going way off this topic, which is one owner's review. I will give it another chance, then houskeeping. We have a discussion thread to talk about it in.

[hitANDrun21]

Let's get back on topic, I have posted my data logs from the ko4 and from the cs turbo. It is on a mostly finnished 91 tune at this point just sight changes being made. If someone with an s3 wants to post a log to compare then please do because I am interested in seeing that myself.

I also want to remind you all I will be running e85 and pushing this turbo harder so stand by for that. I understand you all wanting instant data but I've had the turbo less than two weeks and have a pretty much completed 91 tune. Nishan can only work so fast, he has a life outside of etuning haha

this is unacceptable

Thanks for posting this, It is always nice to see some data and numbers. Helps us do the best we can.

[hitANDrun21]

thought maybe you guys would like an updated log and a vdyno picture. 91 octane, shitty California gas, 20psi

im getting on a dynopak Wednesday so my e85 tune will be completed then with nishan and ill have more data to post.

[dale_gribble]

Why did you cutout cf, boost and afr on vd? What cf for vd?

[hitANDrun21]

CF 1.01

I only post this to show comparison to ko4 hp numbers that I posted before, you can see boost and afr in the data log I posted but I also stated boost was 20psi.

[Vansquish]

Hmm...320g/s @20psi...

I'm seeing 330g/s @20psi with slightly leaner AFRs (11.02 vs. 10.8), a bit more calculated load (2.05 vs. 1.92), and 1º more timing, and about 8º less BAT and identical IAT.

I am running about 20% more WGDC though...

[MD1032]

I mean, he posted the log if you want to put it in vdyno...I put it in and the numbers are right (he must weigh less than I do though...lol), just that it's a shitty log, really wavy for a 4th gear log honestly. But good enough to get an idea.

Damn, that little thing's got headroom yet. Only running 55% WGDC up top and hitting 20 psi like it's nothing. Are you running in interrupt or bleed mode?

Can't wait to see E85 results. I bet you are going to make ridiculous power. You're right, though, that is some seriously shitty gas. And man, your BAT's are high for having an upgraded TMIC.

@Vansquish; you could be like me and flow 280 g/s at 20 psi, similar BAT and IAT...dat stock exhaust lyfe.

I live in san diego where its usually pretty warm, so bats are always somewhat high even with an upgraded tmic. I am running it in interrupt mode, and nishan told me today he runs me a little rich (i think that has to do with my shitty gas) I know its not the best log, I really only posted it to give you guys some more data because I know people are interested. id be more inclined to post the data after I get on the dynopak Wednesday because I know that will yield much better data for everyone. and itll be on e85 which I believe no one else is on e85 yet with this turbo if I am correct.

[acousticdefbot]

yahtzee -- that's +50whp from a drop-in. keep the dataporn cumming.

[Barett@CorkSport]

Anyone catch that he made 15psi by 3000rpm!?

[Vansquish]

3rd gear data from a log from this morning.

AFR......Boost...Calc Load.....BAT....IAT...MAFg/s....RPM
11.32...13.69....2.03...........82......66....156.48....2891
11.32...15.42....2.12...........82......66....164.36....2945
11.17...16.71....2.27...........81......66....192.14....3065
11.61...18.36....2.29...........81......66....204.60....3093

In 4th gear, I can hit close to 19psi by 3000rpm on the S3 too.

AFR......Boost...Calc Load.....BAT....IAT...MAFg/s....RPM
11.32...16.42....2.25...........90......68....167.48....2917
11.76...17.71....2.29...........90......68....176.60....2950
11.91...18.79....2.30...........90......68....182.35....3001
12.20...20.37....2.30...........88......69....194.67....3054

(Please ignore the at-spool leanness. I've been working on tuning that out.)

Needless to say, I'm fairly confident that the S3 can be above 15psi by 3000rpm too. I'm really not trying to shit on the CS turbo, mind you. Frankly, I'm hoping it's a better-spooling, better-flowing snail than the BNR, as competition breeds better products all around.

Subbing for tomorrows dyno results

[hitANDrun21]

update for you guys! E85 tune is done. made 362hp/360tq on the dynopak. @23.5 psi

here is the graph and data log for your viewing pleasure.

[Awal]

Nice! Been a lot of people waiting for this! Sorry I'm new to dynos and vdynos (i know this is an actual dyno) but on your power/torque readings, what is the dotted line? an average, or you last/first run?

Thanks! not new to making cars faster, just new to etuning, and never had a vehicle worth putting on a real dyno. Very solid number by the looks of it, can't wait for it to be picked apart by the tuner pros.

I did two runs on this map, the dotted line was one of the runs the solid line is the second run.

[Awal]

Both runs at full temps? or was the 2nd one heatsoaked, I notice a bit of a drop in power/torque from 3600-4250rpm, then again at 5k-5500rpm (the most obvious differences), or is that just within the realm of normal as far as doing multiple pulls?

Having that much power for that long (3500-6600rpm) is still so nice compared to so many peaky dyno sheets I've seen..

[hitANDrun21]

The second run was obviously a little more heat soaked but it was within 30 seconds after the first pull. Did back to back pulls.

[Awal]

I didn't want to fully assume it was heatsoaked as sometimes people don't start their dyno runs until everything is up to full temp (including ICs, Intakes, etc), then they start from there.

Still thank you many times over for posting this info, it's still very impressive especially since you are just 2 pulls in on your e85 tune, I'm sure there's more to be had in terms of power.

With the TMIC do you plan on eventually running a meth/water kit? Or do you plan on going FMIC?

I am currently checking out the meth/water kits as one of my next upgrades, as you get the added benifit of keeping your TB/IM/head/valves clean without deleting you EGR/PCV. A CS OCC is $200+, but many meth kits are $400ish with reservoirs, I think it's obvious which is the better bang fer yer buck.


So do you plan on taking this tune any further?

[hitANDrun21]

This is the finnished tune. Spent two hours on the dyno with nishan to complete it.

[Shwa]

Thank you, I plan on comparable mods and running 91 (thanks, AZ) and e85 mix and really was wondering where I would end up HP/tq wise.

Damn this turbo for making an already hard decision harder.

[KCi]

The log showed the turbo pushing 350g/s. Pretty impressive for 1k turbo kit.

curious what your mix is?

i made 350hp/360tq on 91 oct pump on my s3 at 23.5 psi. but only flowed 340g/s

[JgamB]

g/s will be relative to your MAF scaling and vary, it's not a direct comparison of power. Either way it's nice to see a completed tune and a car making solid power.

[hitANDrun21]

I'm running a 4 gallon mix for those who asked. And the rest is 91 octane.

[Oni]

Curious how much more @ms3blackmica; thinks this turbo has left in it if IDC weren't the limiting factor here.

Was hoping someone would have commented on the log who know what they are looking at. I'm not seeing anything that screams this turbo is better than the S3. Solid numbers, but same as any S3 or GT(X)28 series turbo with similar mods and tune. Maybe it is the tune, but boost seems to come on late. Is this due to MS3 traction issues or saving the stock block?

When you are running larger intake and aftermarket EBCS, the "drop in" factor is lost. So the price point is the same between this and the S3 and the deal one of the vendors on this site runs, S3+EBCS+3-bar sensor and plug for 1149.99 shipped appears to make it the better deal. Maybe the cost is offset with the gaskets and studs, but It all really only comes down to what is available and how soon can you get it.

My $0.02 anyways.

[speedfreak44]

I was actually thinking the same thing. Seems you need an aftermarket ebcs to realize the potential here along with 3" intake or larger. The only up side I could see is the coolant line and oil line bolting directly up but nothing that couldn't be resolved like any other platform with a turbo upgrade. It is a cool product though none the less especially for someone who had a k04 shit the bed and just wants a drop in with a small boost in power and efficiency

[Easter Bunny]

I think we need some more data points on what this turbo can do on the top end before we can truly say its the same as xxxx. corksport feels that it can move more air on the top end than an s3 so we will have to see.

[speedfreak44]

The prior logs showed near maxed idcs so yea the turbo isn't done for sure needs aux fuel

[biggman026]

Is it bad that I'm secretly happy this turbo doesn't appear to be a step above the S3 at the same price? Obviously a single test case, but if he'd cracked 400whp I'd be mean mugging my S3.

Side note - we'll all be doing this dance again when (if) the S4 comes out.

[JgamB]

Better gas than the 92oct mixed with the Eth would help. I run a bit more timing on 3/9 with 93oct and it frees up some IDC. I also don't knock, and those little knock hits in the upper RPM are causing the AFRs to fatten up to 11.4 and IDCs to exceed 100%.

Whether this was the initial 4 gallons in the 15.9 gal tank to get a 3/9 mix or what will be a consistent 4/8 mix does matter - specific gravity will take more fuel from you.

I'm not convinced this is going to perform any better than the existing 46lb options either as the WGDC went up a good bit to reach 24psi, but there's definitely more in it for someone on meth or running a lower SG mix / better gasoline.

My BNR S3 is producing 386whp 25psi 17.5° 73% WGDC (27mm IWG likely makes that irrelevant to compare) and with a 2.875" MAF ID, 340g/s. It also trapped 117.92 full weight (3487lbs) 2800 DA to back that up as a point of comparison.

Looks like you have the opposite problem than I have at the track. You have trouble hooking the launch? Last time I went (on my E85 tune) I ran a 13.05 @ 110 - no trouble hooking up with awd, but my trap speed sucks (no track prep, full weight, Potenza S-04 tires)
