I haven’t been able to take my car to a drag or test it anywhere cali is really strict when it comes to cars like mine catless downpipes, weistec turbos ecu stage 3 and cpc with cold air intakes what would be the whp of my car like best guess?
also any recommendations on HPFP and LPFP on the cheaper end cause spool is asking for a lot.

after this i’m getting my car retuned by AMR for e30 and wmi from weistec

You can take it to a tuning shop with a dyno? Might cost like $125 a pop but at least you'll get some real numbers.

If I had to guess, with your list of mods, probably ~480whp

edit: If you have a dragy, or other high-accuracy gps tracker, you can calculate an estimated whp figure quite accurately.

@jonathan358 how do u calculate whp with dragy?
if its easy to find online then tell me that and I’ll look
thx

Abdullium

the guys at weistec told me somewhere close to 6 my 0-60 like on a pretty iffy run was a 3.5 and cause right now after I get the car wrapped im gonna do a WMI, Fuel Pumps, e30 tune and tcu as well,
480 seems kinda low considering what they are advertising +212 hp for turbos, +120-127 for ecu and downpipes lets say we lowball the tunes, whp on base c43 is about 328 lets say ecu give 70 and the the turbos give 150 still will put me over 500

MaverickC43

600 whp ?

MaverickC43

I’ve heard with the stock fuel pump over 500hp is tough to do
but I don’t know that to be true

MaverickC43

not sure how accurate this site is, but I know guys have used it
if u got any 1/4 mile times

Quit being cheap if you're going to be doing all these modding. You have already spent $6K+ for turbos + tune. Fuel pumps aren't going to be cheap, Spool Performance is best out there and might be the only option for C43.

Abdullium

your not wrong i’m getting the car retuned by AMR i just need to know if the ones the spool has are worth it cause with all the stuff i have if i do get the e30 and the fuel pumps i’d say 700 is in the wheel house right?

MaverickC43

That’s gonna be a BEAST!!
what tires u riding on?

Abdullium

right now some michelin's the condition is pretty worn

MaverickC43

Stock size?
It’s gonna be a challenge to keep grounded pushing 700hp when ur going all out
Sounds fun!!!
keep us posted when u get some race times!

Abdullium

back tires are 255/35/19 and front are 225/40/19 I think but once I get it all done I will come back and share times.

On this platform for c43/c450 you don't need any of that to go low to mid 11's in the 1/4mile. We are stuck with these times for other reasons. In my opinion you should have found a good tuner first before going all out on turbos, fuel pumps, WMI etc as they are pretty much useless on this platform. You will be disappointed if you are expecting 700whp.

check out my youtube channel. i got a few 1/4mile dragy videos & runs of my C450 with just bolt ons & tune.

I like times over hp numbers, but have u dyno’ed ur car, just wondering?

thegreyone

me? no dyno tune, but feels like around 450whp.

jonathan358

Yeah, not sure where they pull those numbers from but it literally means nothing without knowing their setup and conditions. The first component to swap out after an ECU tune for big numbers on this platform is a fuel pump[s, HPFP/LPFP]. Without those, you won't be pushing anything above 520 even with a full setup. My estimate is mainly based on this premise, but again, it's just a guess. You might have hit 500 but I don't suspect it to be far off of 480whp.

Hi Mav, yes, one of those 1/4mile time hp calculators work. I have used this exact website before and it is very close to my dyno'd numbers.

Spool fuel pumps are the most popular aftermarket solution, we also have members using C63 and E63 OEM pumps. I don't think any C43 will hit 700whp, ever, unless it has a motor swap lol. You will need engine upgrades for anything over 600hp for sure, our open deck design is weak and our pistons soft.
GL with your goal of 600hp on stock tire sizes...

MaverickC43

Good deal man, thanks 👍🏼👍🏼

MaverickC43

These calculate engine hp, not whp
in case people were wondering or didn’t want to read the info on the website

I would be shocked if he was putting down over 500 whp on his current setup. I agree with the above post that he is likely in the 480 whp range. He may get into the 500 to 550 whp range once he gets upgraded fueling and a tune for an e85 blend.

Abdullium

your not wrong i mean im gonna go for as close to 700 whp as possible i definitely think i should’ve gotten the car tuned with someone else but the guy at AMR i talked said they are trying to do something for me to put up crazy numbers cause of the turbos and future fuel mods and wmi you think once i get tuned properly i can get close

Abdullium

the thing is i’m seeing 500 the list but like i said i want to get as close to 700 as possible like i wanna maximize this platform as much as you can

Abdullium

the main thing is no one on this site has done the turbos so i’m hoping with my setup at full i can start hitting mid 10s i saw this guy on tiktok he has fuel pumps and some other stuff and he was hitting like 10.8 constantly so with the added turbos with e85 i can get in the mid 10 range

Abdullium

would that be like plausible if i can find the tiktok ill link it but he had EC tune, downpipes, intakes, fuel injectors w e40 so ill have that with upgraded turbos and he ran a 10.8

C43HeartBoost

Anyone’s guess is just that, a guess. Your best bet now is to get a Dragy to obtain performance data on your current setup. From there you can modify your setup accordingly.
