I cant seem to find a good consistent answers on real world numbers as a basis to judge the acclaimed $1500 gets you 500hp on the N54 platform. I'm not saying this was claimed by VSRF but other vendors have claimed this and I would venture to say that most people would agree. I'm just trying to add up the numbers. Please help me fill in the gaps and add some validity to the claim. FBO's get you 500HP. I'm leaving out exhaust so I may be a little under but just want to make sure I'm not in fantasy land if I'm thinking that I can have a 500hp car for $1500 with a few bolt on's and a canned tune (MHD Stage 2)

Lets use VSRF since it's such a popular vendor on this forum.

Condition of the car. This would be for a 2008 335i 124K with new coils, packs,plugs, fuel injectors and walnut blasting. If I were to put the following car with the following mods what kind of power can I expect to see? I know mustang dyno's are different than dynojet etc.. and there can be quite a bit of variance but give me a ball park. I'm under the assumption with 15% drive train loss that with the below mod's I can achieve close to if not over 500HP or 425 WHP with out meth. Is this True or False?

Base Car 255WHP +120WHP (mod's below with gaps) = 375WHP (431HP) I'm missing 50WHP? What's the inter cooler net you? I dont see any numbers on this in the marketing info.

Manufactures typically exaggerate their claims or the conditions are such that's not typically street conditions or every day driving. So their numbers are typically inflated. so I'm a bit skeptical when they claim 20 WHP for a DCI. So it's hard to speculate how accurate any manufactures claims really are but this was taken from the website and a basis for measurement.
If people with real numbers based on empirical evidence (dyno sheet or virtual dyno) could chime in I'd appreciate it.

VSRF Catless Downpipes = 25-30 WHP
VSRF DCI =20 WHP
VSRF 7"FMIN=??
MHD Stage 2+ Tune = 75 WHP or 100hp

Can anyone confirm these mod's net you roughly 500HP? Based on my basic math I'm missing about 50whp how much does the intercooler provide (trick question)? The real question is with the listed mods how much power does the car really make? I've seen numbers all over the board. Remember that I've got no boost leaks new plugs, coils, and walnut blast so these are optimum conditions. No misfires etc... car is running great. Diagnosed by INPA

I am trying to justify in my frugal mind to spend $1500 on parts so I can join the 500HP club on my 3rd platform. I want to get there as affordable as possible.

In a nut shell I just want to know if I get DP's 7"FMIC and Tune would I be joining the 500HP club. Yes no maybe?

500 HP FBO requires a top notch tune and quality parts. It's a lot more realistic if you added turbo inlets into the mix.

Just saying but the DCIs will not make 20hp it is more like 5-10. FMIC make gains around 5-15 hp. People usually get around 10. I could be wrong but this was what i got from seeing other peoples' dyno logs. As for FBO n54s they will make 400whp max with more being around 360-380 whp. Making 450whp with an e85 mix isn't too far off. It all depends on how healthy your engine is, the IAT, as the conditions of your turbos and fueling systems.

Have a look at this thread:

It seems MHD stage 2+ nets around 380whp ish with FBO on 93 pump based on other threads ive looked at and a couple of youtube dudes

This seems like Dynojet numbers too.

To do 500whp i would think you would need some big hybrids and an awesome tune on pump or some fuel sweetners like meth or eXX

[Chris@VargasTurboTech]

Maybe 500 crank hp. 500 whp on stock turbos is pushing things very aggressively and not all cars will be able to achieve this. There have been half a dozen or so guys that have done it.

[TemjinX2]

there probably talking about crank hp. Non car people go by the crank number since thats what car manufacturers use. People who mod cars tend to go by whp. You can probably hit 500 crank hp with FBO and e85

Simple answer...no

[Brandon818]

No intake gives you 20 wheel lol, it's all B.S. Mod your car, your going to be happy! then dyno and find out where your at, worst case, add inlets and meth!

[cruizinmax]

People always get confused wheen looking at hp gains and think that all the quoted gains happen at the same rpm. Intakes may gain 20hp but it may not be peak hp. It may be at 2500rpm and only 1-2hp at peak. Or in some cases lose peak hp. You can't get caught up in the marketing hype.

[NoGuru]

I hit 398HP with FBO and MHD Stage 2+

[JM98]

You can’t stack HP and mods like that lol. Realistically you would need

Downpipes
Inlets
Stage 2 Fuel pump
Intercooler
Custom e40+ tune

This would net high 400s, maybe 500 on a glory run maxing out the turbos

Id say Turbo's.....More like a single and a 6MT + twin disc to hold it with any reliability.

Next, say JM says....

You cant just stack mods at their given HP gain and think its going to add up

IAT's will be a huge issue, fuel pump + accessories, etc.

Even with all everything you list n than either a single setup or better inlets will be what pushs you over 450rwhp.

Than i think its same to assume you have an auto, the trans is good til about 450rw, then you have another issue. + 125k you have on your car, just do a tune with a mild kick in boost, FMIC, DP and other bolt ons & be happy @ 400rw

going past it will cost you big.

That's what I was thinking... plus like others have said you can't just add up advertiser's quote you'd have like a thousand horsepower. That's been well-known since forever back in the days of carburetors even. We definitely can't believe everything companies try and sell us

And, there's about 15% diference between horsepower and WHP. Mine made 365 at wheels when I dyno'd it last with stage 2+ and catless downpipes. I have all wheel drive so the tires barely chirp at 2500rpm launch and the car is like a rocket to 60.

[Rob@RBTurbo]

IMO it's most reasonable to expect around 425-450rwhp with all supporting mods (including inlets) and fueling (ie. race gas, stout Ethanol blends, meth) on healthy stock turbos in kill mode; but add in a very generous dyno and you can get even more paper power (ie. not be any faster in the real world).

Rob

[Thewind727]

all things in my sig with a custom tune on full e85 got me 461whp on the stock turbos. im tuned down now running a custom e50 blend so my hpfp can keep up but yes 500 crank is possible but its not cheap and you'll be maxing out you factory turbos to get there

[fordbaxter]

Another thing to consider is each mod doesn't provide the same gain if other supporting mods are not present. Downpipes aren't going to net the same HP with and without inlets, IC, etc. The mods work together and most manufacturers post numbers from cars with various mods installed.

[bpdef29]

For what it's worth, I'm FBO with VRSF goodies and running MHD E50, and my Virtual Dyno reads about 415 WHP. I personally wouldn't run a more aggressive tune than this boost-wise on the stockers.

VD shows a delta of about 170 WHP over stock, which, if somewhat accurate, is a huge gain for a little over $1k.

[GEOS07335i]

Thanks for all the input. I guess I could throw inlets into the mix but they sound like a major effort to install. And it sounds like it would get me closer to the 500hp@ crank power. So any good recommendations on inlets? To relocate or keep stock location? Sounds like inlets would increase volume flow thereby increasing efficiencies on IC, and turbo and keeping boost on target for longer. Also are there issues with installment im reading nightmare stories where people are having a hard time with holding the inlets inplace and all the re routing of stuff.

Also not sure I understand something. If I don't plan to go with a E-mix why do I need to up upgrade LPFP. I didn't think you would run out of fuel on stock turbos.

So if the norm is 400whp or 460@crank what would this typically equate too at track on street tires for 1/4 mile runs. Is this a mid 12's low 13's or high 11's?

[Brandon818]

It would be a good idea to run an E blend. Personally speaking E85 "feels a LOT more powerful (butt dyno)". Also its rather addicting, once you try E, you never want to run regular pump gas again lol.

I know several people with 160k on there's ST on one and Full FBO on the other. Mileage has little to do with motor health as long as good maintenance is done and car is healthy. Mine is pretty healthy it should be fine.

[dyezak]

Right now I'm beyond FBO (coils, bucketless lpfp, full e85 etc) on an engine/car with 49,000mi, my logs are flawless with no risk of any kind, and a custom tune that is safe, and not pushing anything.

500wtq and 430whp.

We could easily eclipse 450-460 on my car by doing inlets and outlets and retuning for that. But the hassle of those mods aren't worth it to me when I'll be ditching the stockers soon. But even on my car, 500 on the stockers would be pushing things really hard and wouldn't really be that safe.
