How much boost can a stock engine take
The engine I chose for this test was a motor we built for the Popular Hot Rod Engine Master Challenge. It is a 414 CID LS motor designed to run on 91 octane with power approaching 700 HP. When testing Race-Gas I was being careful watching the data stream for knocking. The biggest benefit of nitrous is that it provides enormous "bang for the buck." You can purchase a nitrous kit, brand new for around $500 with everything you really need to start using it, maybe as much as $700 if you get all the bells and whistles, and instantly strap on 15, 35, 55, 65, 75, 125 or even 150 horsepower. Im thinking of getting the HKS GTII soon, and plan to buy these other mods as part of my build.. up-graded fuel pump and injectors Motec 800 ECU blueflame downpipe de-cat test pipe manifold (not yet decided) Inter cooler (not yet decided) im worried that this will push the power above what the... Our engine lived for ~9 months, being nearly daily driven at 17-18psi of boost, approximately 350rwhp! But it eventually could not take 2.5 times the factory power, and here is the result: Be careful with how much boost you are asking your NA engine to take. If this engine was limited to 10psi, it would probably have lived for many years. The big engine may be happy with an 11.5:1 A/F ratio, but you may have to go as rich as 10:1 on the smaller motor. Finding the exact A/F ratio to run can be somewhat tricky because nitrous carries its own oxygen. The ratio in effect becomes a variable of how much nitrous you put into the engine. The following equation to work well as a starting ... The best quality octane boosters on the market can raise your octane values by 5%. The average is about 3% which is enough of a boost to see an improvement in engine knocking. Don’t believe super hyped ads that promise huge increases in the octane ratings. Have realistic Expectations – Don’t expect miracles from using an octane booster. Just depends on how much you drive it. Stock with the 600-750 rwhp for a daily driver. And rmember no matter what, on pump gas 550 is your max. Engine Masters, presented by AMSOIL, is an all-new show featuring parts testing and engine-to-engine shootouts. Developed from the popular Engine Masters Challenge -- a dyno shootout event also presented by AMSOIL -- Engine Masters is hosted by David Freiburger of Roadkill, Steve Dulcich of Engine Masters magazine and Steve Brule of Westech Performance Group.

I do not consider the factory crank to be a weak point on an N/A build up. So I would have to say 350HP ball park should be considered a safe limit for the factory stock 4.7L internals.

Is the question, how much boost can you safely run on the stock msm turbo? Or how much boost you can safely run on a stock engine with the msm turbo? Both are relative, but different. Our stock turbos are really only good for 12-14psi. I run mine at 12psi but it creeps a little bit to 13.5-14 on colder days since I don't have a ported wastegate ...The stock turbo can deliver around 1.7 to 2 bars of held boost. To run 1.3 or 1.4 bars on standard internals, you dont need different rod bolts or head gasket, just a proper boost controller like you are planning to buy and an ECU without the fuel cut in it, lots to choose from. The engine has stock internals, only mods are Mass Flow Sensor package, 944T injectors, and high flow fuel pump. I can adjust timing, fuel, and control intake temperature. I just want to know (under ideal conditions, assuming it has adequate fuel, timing control, and sufficient oil cooling and intercooling) how much power the 3.2 can take ...

It doesn't take much to overfuel a stock naturally aspirated engine, often with disastrous results. Safety as always is important. On that note, probably the first thing one should do would be to disconnect the batteries, to ensure there is no power to the pump, or at least remove the wires so that if/when you rotate the engine, it will not start. that engine will take about 14 psi of boost maximum before you start running into problems, then the cost goes up incredibly after that. anything over 14 psi you will certainly have to have new injectors, a new ecu, new turbo, exhaust manifold, intercooler, wastegate, dump valve all up-sized to take the extra strain, let alone cam shaft, bottom end re-work, clutch, gearbox. Jan 18, 2007 · A safe amount of boost on those motors is around 10 or so, with a good tuner. Be cautious on who you have tune that motor, make sure they understand the difference between the timing of the OBD2 and OBD1 SOHC vtec motors. Aug 03, 2011 · I've been running 26psi for quite a while. Ran it at 30 for a week or so. As someone else mentioned, the real danger comes from making too much boost down low. I'm only making 15 at 2800, and 26 by 3600. Also, with the mbc installed, it was holding 30psi to 7k. That was fun, but scary on stock internals All forged internals doesn't tell much about build. Dedicated N20 engines run unique pistons, ring gaps, and cams with exhaust bias to compensate for the high cylinder pressures. Typical 351W hotrod build, wouldn't push more than 250hp on an N20 kit. Stock block and N20 build.. Could get a fogger system and approach a 500hp boost.

Aug 08, 2014 · But at the same time opening up the engine can bring about a whole new set of issues. I would say this car, if taken well of can survive quite well at 550-600whp on e85. A prime example of that is Phunk, he has 50-60k miles with his greddy TT kit making over 550 (if not 600) on e85. _____
The LS3, like many of the other modern engines that are in production today, are more than strong enough to handle much of what you can throw at it, to an extent anyway. Many individuals and engine builders have pushed the LS3 into this realm of horsepower on the stock internals without fault.
an engine with a VE of 100% should be able to cram in exactly the same volume of air as the calculated volume of the cylinder. Because of restrictions in the intake, however (primarily the venturis on carburetored engines), most stock engines have a maximum VE of around 80%, while most race engines hover around 95-100%. With the proper cam and/or ram air
Sep 10, 2011 · Trying to take it off incorrectly can crack or break it causing your intake not to function correctly. This can lead to performance issues and CEL’s (check engine lights) Here is a guide on how to take it off properly and make it easier the next time you take it off: How to take off the 2.0t fsi engine cover ←
Apr 19, 2009 · The amount of turbos doesn't matter to the engine. I'm not sure what a stock 370 motor can take for boost pressure but chances are that most of the ones you see are twin turbo because of them being a V6. There are single turbo V engines but the packaging can be tricky on those.
There is another popular turbo class called T3/T4. This was designed to fill the gap between 300 and 550HP configuration. This class of turbo is ideal if you want to start out with a stock Subaru motor to produce about 300HP, then later upgrade the internals (rods-pistons-block-injectors) of the motor to produce 400+HP.
For example, motorcycle racing engines can use compression ratios as high as 14.7∶1, and it is common to find motorcycles with compression ratios above 12.0∶1 designed for 86 or 87 octane fuel. Ethanol and methanol can take significantly higher compression ratios than gasoline.

May 11, 2015 · A reasonable maximum FCR for an engine with aluminum heads on 91 octane pump gas is around 11.5:1. The uncompressed air in the engine at BDC is equivalent to one bar of pressure, or one atmosphere. At sea level, this is 14.7 psi.
