S4Matty supercharger and throttle body porting got me 30 whp!

**Bruno_s4** · 05-09-2018 12:08 PM

So I’m extremely pleased with the port work done by S4Matty!!
I was looking for some more power but didn’t want to go dual pulley (I track the car on road courses) so porting was the next logical step.
Luckily Matt is only 1.5 hours away from me in Niagara Falls and since I just couldn’t make the time to go to him, he was nice enough to come up to my office to do the supercharger/throttle body swap for a reasonable price.

Since I had some time before I figured I would get a before and after dyno.
Contacted Eurocharged Canada who just installed a new Dynojet about 3 years ago and went for 3 pulls last Wednesday.
A really great shop that works on high end high hp vehicles. They are well known for their work on Mercedes (especially the C63), BMW, Audi, Porsche, Ferrari….
Did 3 pulls and highest power that day was 387 whp and 353 torque and it was 29C (84F).
Pretty good for GIAC Stage 2.

On Monday Matt came by and we swapped the superchargers.
He did a great job being careful during the install and we even had a look at the valves…. They were fine. Not much buildup at all and didn’t need a carbon cleaning.
Overall a real class act that cares more about the quality of his work than the quantity.
Each charger takes him roughly 8 hours and you can tell as every single area has been touched.
Having my stock and his ported side by side helped notice the difference.

He told me it may take a couple days for the car to adapt so today I went back for another dyno run at the same shop but it is 2C (4F) hotter today so I was a little worried.
First pull 405, then 409 whp… not bad.
Let her sit for 20 minutes and did 2 more pulls.
412 and final was 417 whp!
As you can see from the chart I went from 387/353 to 417/376 with Matty’s ported charger and throttle body.
And each pull (from last week and today) my IAT’s stayed stable at 43C (109F) so the PLM is doing it’s job.

For $800 (Canadian) + install it’s the best money I’ve spent on this car since going Stage 2.

Do you have any extra TB's like a core exchange? I have an extra blower that no one seems to want to buy would possibly be interested in your porting work for the supercharger as well as my TB. I live in Buffalo so not far away and could drop off for you to do at your convenience, I just dont have an extra TB and cant really afford for my car to be down.

Thanks.
It wasn't cheap but I just had to know.
My but dyno is happy but wanted some proof.
I regretted not doing before and after with other mods on other cars in the past.

**cjw** · 05-09-2018 12:44 PM

Sweet. I'm also curious as to the IAT drop with a ported blower.

Feel like accepting another charger/tb combo in the mail? I have one of your old ported tb's I bought off a member here. I also have a spare blower that I'd be interested in having ported/matched.

**waxxonMTL** · 05-09-2018 01:03 PM

Very nice ! Your experience with porting seems much easier than mine.. I kinda regret the route I took lol :(

Could you share your experience?

**GandalfTheIbis** · 05-09-2018 01:10 PM

Waxxon, please do share. I imagine it has something to do with the flaps under the throttle body? or was it just a bad experience with another party?

Bottom line is ; bruno had a turn-around of 1 month and paid 800$

My turn-around is like 4 months and paid double lolll !!

**Loe** · 05-09-2018 01:15 PM

man, I knew a port job was the beez neez, it woke up my car a good bit, but wow that's incredible! Even more-so because it's just stage 2 and not DP, looks great!

Well it was more like 2 hours of install time. :)

But about 3-4 weeks wait to meet up with Matt.
The problem was the outside weather not with his availability.
Sorry to hear about your trouble Alex.

Yup you are absolutely correct!
On a dual pulley car would be bigger gain.
And uc even more since it can be opened up alot more.
The inlet is not the most important part of the port job though

I certainly could do that.
I'm just not sure on shipping costs to the states.
Cant be that much.
Me being Canadian funds kinda makes up for a higher shipping cost I'd think

Nice gains for just upper pulley and no heat soak

Matty is the S4 back on the road?

I'm sure once installed it will be a thing of the past and won't look back, but I might hit up matt for further work later this summer when i go for the detail trip, as we said sooner this PM :) I don't have any TB ported ;)

I forgot about you coming this way for detailing.
I definitely want to get on the list as long as I get some paint issues addressed before you come.
