Has anyone actually done the turbo upgrade ?. I just went through old forums but nobody said anything after getting it done. I know the stock motor cant handle it but has anyone upgraded to the weistec ones ? Thanks
Currently stage 2 fbo

if the tuner knows what they are doing the motor will be able to handle it. Torque will kill the motor rods. a lot of us heavy modded guys are running 475-500WHP and 600+ft lbs of torque. The car falls off pretty hard on the upper rpm due to not enough air from turbos. as long as torque can be capped, bigger turbos should only help.

I am currently looking into turbos for the future and I think it will make this car even more fun.

Hi,
I am in the process of tuning my SLC43. will be completed by the second week of October 2022.

Looking for more top end currently has more than enough early too mid range power. Stage 3 consisting of:

· Comprehensive ECU tune (WEISTEC)

· Race air filter kit

· Stage 3 turbo (WEISTEEC)

· Water Meth Injection (WMI) kit (WEISTEC)

· VTA kit, blow off (WEISTEC)

Let me know how that turn out I was gonna get a weistech tune to see how it is first, then i was thingking w.3

Mavic C43 AMG

Did anyone try out any of the weistec products like the tune, turbos, or meth?

need2speed

Interested in hearing your experience if done?

I would also love to hear more about this 😎

Aemami

nice..what upgrades and tune are you guys running to get those 500whp and 600+ft lb torque?

hmcparland

hopefully I get the car back by the end of the month.

I live innNew Zealand so the turbos were shipped to the US for modification. Just waiting for them to land back here

all bolt ons except turbos. intake, intercooler, downpipe, high pressure pump low pressure pumps.

Got the car back today, drove 600 kilometres home. I don’t have dyno fighres, can say it is neck and neck with F Type Jaguar SVR 5.0 V8 supercharged on. Rolling drag race, so pretty happy as that car is pretty quick.
in Summary also had the Weistec TCU upgrade. Was needed as TCU was limiting g the power and the gearbox needed the higher line pressure to avoid slipping and speed up shifts.
W.3 turbo upgrade, ECU and TCU flash
water methanol injection
Weistec blow off valves
high flow air intake.
No cat delete as would not pass warrant of fitness without.
other thing is replaced all tyres with Michelin Pilot Sport 5’s
and critically wheel alignment with 1.5 Deb negative camber. Stops under steer, and gives more bite to the front end. But be careful as when back end let’s go very hard to catch it. My car has LSD

hmcparland

Yes, I have

C43HeartBoost

Do you have a Dragy? If not get one and post up some 0-60, 1/4 mile and 60-130 times.

@hmcparland ever get any dyno figures or any quarter mile times? Anyone else know someone on this forum that has the Weistec turbo upgrade?

hmcparland

Went to recent Dads day drags on an unprepared track. Very slippery but improved throughout the day. Best was a slow 12.8 @ 112.3mph 0-60 ft 2.495

C43HeartBoost

Not to be a jerk, but unless your post is relevant to the subject matter of this thread - so what? I assume you do not have upgraded turbos - in which case, there is a 1/4 time thread you can post times in.

hmcparland

Well the thread if you look for the backup was asking about cars that had had the Wisetech W3 turbo upgrade and other upgrades. I was asked if I had any quarter-mile times this is the response to that so if it’s not relevant please delete the post.
I had detailed the modifications done to the car as people were asking if anybody had done this

C43HeartBoost

My bad 100%. In fairness, it was me who asked the question - almost a year ago. Unimpressive times for the upgrades. About 1 second off the stock 1/4 time - which is great, but that is on par with just a good ECU tune.

hmcparland

I think you have missed the key information in my post. Traction was a significant issue on the day and with a 0-60ft time of 2.495 seconds no chance of getting in to low 12’s Short wheelbase, low profile road tyres and firm suspension don’t help with traction. But hey ho it’s not a drag car but an incredibly fun road car. If you think a good ECU tune will do the same good for you.

@C43HeartBoost glad you took responsibility for the bad because I was about to light you up! Been drag racing for years, @hmcparland you are correct with a 2.45 60ft the time and mph are worthless. Bet you would put up some reaaallllyy impressive numbers your next go around. With my Eurocharged tune and intake, I know my car has a 11.99 or better in it with good air (DA) and some cool temps. I'm in MD, and hoping to maybe get to the track tonight.

Were you tuned prior to getting the turbo upgrade? If so, was the turbo upgrade the same butt dyno feeling? What I'm asking is stock vs. tuned was night and day (for me), and I'm assuming tuned vs. turbo upgrade was the same feeling? Thanks for your response in advance brother!

Side note- my man Bayhas @Eurocharged_HQ is getting me a MS100 tune, and I will post all of my dyno numbers (I'm going to go stock vs Eurocharged tune vs. Eurocharged MS100 tune). I know with that tune and race gas this car will really be putting up impressive numbers and quarter mile times.

hmcparland

standard, before Weistec upgrade. Big difference in how the car drives especially the instant torque from low rpm. I do doubt the claimed 540 bhp, but runs pretty well to around 130mph, then like many cars you still want more horsepower. It is very easy to overpower the tyres and traction control in lower gears. It is a fun car, a bit of a handful as the power comes on hard very quickly, part of this is the transmission retune that removed the torque limiting maps in the standard gear box. For some reason our local track feels like driving on ice with street tyres. Impossible to jump on the power until you are going more than 60 mph. One day will get it on a dyno, none local to where I live.

Thanks for the response! I forgot to mention, I am in a GLC43 but you probably picked that up from my username. Where are you located? Elevation is another big factor for quarter mile drag racing too.

What we really need developed are fuel mods to allow e85 tunes on this platform just like BMW/Audi tunes. E85 with tuning i am confident, would get our cars into consistent 10's 1/4mile. I'm so close now, but without a proper e85 tune I dont think its possible without risking engine failure. Upgraded turbo not needed.

C43HeartBoost

I agree with you regarding the need for a mainstream e85 tune for this platform (assuming the HPFP, LPFP and other upgrades needed to reliable run above e30). I have been running e30 on my Stage 2 c43 for over 2 years. Fast and fun car, but I have hit a ceiling as I am not putting more $ into the car given the limited aftermarket support fort the platform. Selling the car in about a year anyway for the next project.

thegreyone

I considered selling mine too, but it looks dam too good to sell lol. So kept it & got an Audi RS3 now.

Can I ask whats been your best 1/4mile time with E30? Im currently stage 2 with just I/E/downpipes/intercooler - full weight 11.49@120mph.

I've hit my ceiling as well. Im waiting for some cooler weather to do some more passes soon.
