Final result with SFS prototype 3" TIP and the R-Tech Prototype cold air box for cone filter.  We founf the torque we was looking for.

The maf logs show a huge gain in midrange torque which are backed up by the dyno plot.. 290+lbft  The best 023 results I think I have ever seen?  The aim of the/design of SFS tip was to make more midrange power not peak bhp/ flow gain. The is no evidence saying this tip will make more PEAK power vs the other TIPs on the market, at this stage of tune its about the same but the other tips could flow better at the top end when going 285+bhp or hybrid turbo

If your looking for peak power over 285+bhp or going hybrid turbo then from what I have seen the Badger5 v1 has proven numbers and I have tuned many cars with B5 V1 tip fitted.

If your only looking at spec1/ spec2 power 280bhp then from my testing the SFS is a very good investment IMO.

 The main gain from the SFS tip is the turbo spooling and air speed, this allows the turbo to spool and draw more air faster from lower rpm which resulted in peak gains of 16lbft..

Final result with SFS prototype 3" TIP and the R-Tech Prototype cold air box for cone filter.

The maf logs show a huge gain in midrange torque which are backed up by the dyno plot.. 282bhp/290+lbft  The best 023 results I think I have ever seen?

The back to back maf logs with the B5 3" tip v SFS 3" tip show the peak air flow gain is around 2gs (2.5bhp) more with the SFS tips but this can be put down to many factors as its such a low reading..  The main gain from the SFS tip is the turbo spooling and air speed, this allows the turbo to spool and draw more air faster from lower rpm which resulted in peak gains of 16lbft..

I left my usb stick at work so I dont have the logs to hand, but if you check out SFS facbook you will see the graphs I emailed to them.

Very cool Nick, and great results as well (as predicted).

Unfortunately I can't look at Facebook out here, blocked as it's "Personal & Dating" LOL.

Look forward to graphs.

Well I went down on wednesday bright and early to get injectors and MAF tweaked in.  Nick got it on the dyno and did a run to see what it was doing, really bad misfires which we initially thought was fuelling.  Checked fuel pump for pressure and found to be weak, so replaced that with a R-tech tweaked uprated 225lph pump   Made nice pressure on the rail but still a misfire so we tried adjusting the fuelling on both ends of the scale and still remained so was down to hardware.  Tried a set of coil-packs which instantly made it a lot better and limited the misfires to one or two on peak boost.  ordered a set of new genuine coil-packs from TPS and stuck them in and back on the rollers to get the fuelling set up nicely.

Made consistant power all day after the engine got over its misfires which is great and proves the great efficiency of the THS intercooler.  I looked at inlet temps late on in the day and wasnt more than 28.5c at the inlet!

So after about 4-5 hours changing maps and running on the dyno, we got to a figure which was great!  Achieved 247bhp@4506rpm and 297lbft@3660rpm. 

heres the graph of the above:



The torque figure as dropped down to protect the rods from damage so end result was 248bhp@5172rpm (228bhp@wheels) and 277lbft@3112rpm (262lbft@wheels).


Feels like a totally different car and is such a pleasure to drive now.  There is just power in every gear from every rpm all the way to the redline.  Still had plenty of pull at 140 which is just madness!!! (on my private land)

Really cant recommend Nick and the team enough, the amount of time and dedication, and customer service is just totally unreal.  Never met anyone like the team there!  Even mate said they are some of the most friendly, advising and knowledgeable people around and he had only met them this morning.  Cant wait to take his GT28 clio down to them late this year


It was always going to happen at some point aswell:

cant wait to get this on different sets of rollers to see what it makes, but as we all know, peak bhp isnt always the best option!

lol I would take massive offence to all that sh!t talk if I was you and Nick...

I remember tshirt2k, thread in mk4 section not to long ago:
http://www.golfgtiforum.co.uk/index.php?topic=209277.40

I'll back nick up on the results, as I have seen other European tuner's pull similar out the hat with the following setup:

Any dyno is a lottery, your figures will vary from time of day to time of year, that is a k03s on an AGU... he's got:
63.5mm exhaust
1.8 NA camshaft
large injectors
Forge cold air intake
Forge actuator (blue spring)
Stock K03s turbo
4bar FPR
Larger MAF
FMIC

Tested on Maha dyno, 100octane fuel, 25degree advance... and it's in a polo.

Also nick you familiar with the 20vT cams being swapped with the 20v NA cams? Any idea on degrees and benefit?

[RTechUK]

Keyboard warriors who aint got a clue...lol  maybe they had a k03s setup on a generic stage 2 map.
You can not make 240bhp+ on a k03s with a stock actuator, but with the forge actuator with added spring load then its another story.. .   Most of my dyno plots have been back up on JKMS dyno in the past, and my maps tend to see higher numbers on other peoples dynos, plus Chris has all the maf logs before the yellow injectors where fitted with the stock maf which showed 230+bhp with n75% below 90%..    

You might want to do some maf logs chris and post them up, or even find a local dyno..

Yer the turbo is being ran out of the "paper work"compressor map, its being ran to the limits I have been testing for the last 4 years, and at a point I am happy to tune to with the supporting mods. If there was an issues running it this hard then I am sure I would have many many unhappy customer with naf K03s turbo.

If your on clubgti you might want to point out my k04-024 map, which made 270bhp from stage and badger 5 tip, which one of there sponsors tested and said in a post its the best k04-023 he had run on his dyno at the time.

My stage1 K03s maps make 220bhp with easy with just decat and FMIC and "good fuel" 

[Chris.]

Ill get the MAF logs and get them up at some point, just need some more fuel in haha. Over £100 of fuel in the last week but more than worth it!  I even have maf logs of 184-187g/s and that was before injectors and a larger maf housing.

Car ran consistently in the 240s  I dont think at one point during all the map files it made less than 240bhp.

Car will go on some local rollers at some point this year!

Which blocks can i log for things?  I know block 002 is MAF.  Block 025 is the N75 duty cycle.  Correct? 

Which one logs the ignition timing?

[RTechUK]

13 is what you want for timing pull, this in a fasion shows your getting enough timing its how I work, I work up to around -6 or until I stop mapping power on the dyno with increments of 0.75deg on the whole advance table, then work at WOT on the full load points vs rpm.


184-187gs = 230bhp which if I remember is what the dyno spat out as well..

[Chris.]

Sweet!  Whats the calculation for the larger ID MAF?  Is the the MAF figure * (the increase in surface area of stock vs larger MAF) / 0.8? 

[RTechUK]

I would not worry about it too much Chris..
