How much boost does a GT500 Supercharger add?
I plan on upgrading the car with a pulley that increases boost by about 3 psi. The factory supercharger on all GT500s makes maximum boost of 9 psi. The GT500KR and 2010 GT500 add an FRPP CAI and upgraded computer program (tune) to get the additional 40hp.
What's the difference between the stock psi and the GTI?
They both are running about the same PSI just the GTI is being less aggressive on the timing and fueling due to the stock software. I really cant wait to get software on the GTI, its going to be such a beast. From what others who already have the software say, I should be holding around 1.8bar or 26PSI once I do get it.
How does the stock 2016 GTI compare to the GLI modified?
The other thing I noticed is that the time it takes to build that pressure up to 20PSI in the turbo is also significantly shorter, this does explain a lot as to why the stock 2016 GTI feels similar to my 2006 GLI modified performance wise.
How to add 40 hp to a GT500KR?
The GT500KR and 2010 GT500 add an FRPP CAI and upgraded computer program (tune) to get the additional 40hp. Adding a CAI (whether FRPP or C&L or JLT) and tune to an '07-'09 GT500 gets you at least even with the power output of the KR and the 2010 GT500.
How much boost does a stock MK4 GTI have?
I reckon the MK4 is good anywhere between 7 to 9/10 PSI.
How many pounds is a boost?
Most turbochargers stop producing boost after 20 to 25 pounds have been reached, although they are capable of much more. Superchargers, also capable of greater boost numbers, typically build up to a maximum of thirty pounds of boost.
How much boost can a mk5 GTI handle?
Maximum boost on stock engine internals for GTI / TSi version is 2 bars (~310 bhp). Golf R moddified engine can hold up ~350 bhp @ over 2 bars (29 psi) on stock internals.
How much power can a GTI make?
The engine inside the GTI is capable of generating 228 horsepower, which is impressive, but where it really shines is torque. The turbocharged engine can produce 258 lb-ft of torque, allowing the hatchback to zip around corners, accelerate quickly and get its passengers where they need to go in a jiffy.
Is 10 pounds of boost alot?
The reason so many folks cite 7-8 Lbs as a maximum safe boost level is because of the amount of effort, expertise, and $$ it takes to go beyond that. Most of the bolt-on FI kits that ship with a "canned" tune and questionable fueling are going to play it safe and keep things at a lower overall boost level.
How much horsepower does 6 pounds boost add?
Typically you will get about 8hp per lb of boost you are running. Our car could probably take 6psi without doing anything... which is about the limit you'd want to run without an intercooler.
How much power can a stock GTI handle?
~385 with the IS38 upgrade. APR is claiming 450-500 with stage 3.
How much HP can you add to a GTI?
You can expect 15-30+ horsepower gains depending on the turbo and tune setup.
How much boost can a K04 handle?
The typical K04 software usually ranges from 15-20 psi.
How much HP does a Stage 2 GTI make?
APR Stage 2 ECU Upgrade This upgrade requires an APR Race DP and produces 334-351 HP with 338-392 FT-LBS of torque. Gains as high as 110-117 HP and 93-120 FT-LBS of torque are available throughout the power band (210 PS Model), depending on octane and torque level.
What does GTI stand for?
Grand Touring InjectionWhat does Volkswagen GTI stand for? GTI stands for Grand Touring Injection. Volkswagen uses for its direct fuel injection system. Over 40 years ago, GTI technology was first deployed in the 1976 Volkswagen Golf GTI.

What does 15 psi boost mean?
15psi refers to sea-level atmospheric pressure. Increasing the power requires increasing the volume of air-fuel mix in the cylinder in the same time, i.e. increasing the velocity. So the design of the intake becomes a limiting factor. At the design limit more pressure will just heat the gas following Boyle's law.
What is boost a measure of?
The pressurized air being pumped in to the engine is called boost, with the pressure increase compared to ambient air pressure measured in PSI or bar/kilopascals.
What is a bar of boost in PSI?
IIRC one bar equals 14.5psi (or 14.5037738 out to 7 decimal places). So: Code: 0.1 bar = 1.45psi 0.2 bar = 2.9psi 0.3 bar = 4.35psi 0.4 bar = 5.8psi 0.5 bar = 7.25psi 0.6 bar = 8.07psi 0.7 bar = 10.15psi.
What is psi boost?
The pressure is referred to as boost and expressed in pounds per square inch (PSI). A turbocharger may be able to move enough air than the engine can use even at low pressures thereby causing an instant boost that impacts power. The greater the turbo boost pressure, the greater the engine power.
