Safe amount of boost on stock engine?
Anyone know what might be a safe amount to boost on a stock engine before having to build the internals?
Just weighing the option and prices for now. |

I dont think anyone knows. if you boost at the levels the tunes come in i would say thats safe.

All depends on your tune , kit and the way you intend to drive it
My estimates from hours of lurking around here 10~ on 91 14~ on 93 thanks to king tut 16sh on 9X + WMI 20+ on e85 Obviously this is the amount of boost, you have to consider fuel issues , drivetrain and cooling My 1 cent

I heard via the ecutek and haltech networks of a few cars throwing rods around 300 whp!
Apparently it's just a load limit on the rod when it sees bursts of extreme accel. There's a lot of big number charts on here but how many of them saw extended, high load use outside of a dyno room?

Water/Meth injection seems like a good option if you have limited access to E85 or want to wait on building the motor. Ptuning is pulling 400whp on 93 and meth injection on the stock block. More than enough to get you in all sorts of trouble

Meth Injections = Rusty part + 70% more for catastrophic failure (Not practical for every armatures ) E85 = Very few fuel stations, and the Fuel consumption is 2-3x times more of the traditional 93. Your full tank of gas may just serve you 1/3 of the original mileage range The best possible is to build a car running on 93, with conservative tune. The good news is that with 93, and running around 10 PSI will have you in the range of 300-350 RWHP already. This already makes this car into a beast |

im on 93 and 5.3 psi at 286hp and with exhaust close to 300 if not 300 so its very safe because i beat it up. next week or two ill be on 10 psi pump and e85 so hopefully ill be around the 400++ so ill beat that up and tell you if its safe also but it should be lol

It seems most people on this site are not really that interested in the timing that cars are running as compared to the boost that they are running. The cars making good horsepower numbers on lower boost levels are going to be running considerably more timing. You throw in some E85 or meth and again you are going to be running considerably more timing. To get the total picture of how a kit is running you would need to see dyno plots with horespower, torque, afr, boost, and ignition timing. TL;DR: There is no correct answer to your question.
