Safest RWHP for daily driving

[Moreboost88]

Whats the safest RWHP for our cars if you are daily driving it and don't want to have any engine problems? I heard it was around 650-680, also I have the stock blower with a 2.6 pulley, I want to get a twin screw (at low boost) with supporting mods, but was curious if it might cause more stress on the engine as opposed to my pullied eaton?

Thanks

17-18lbs of boost for pump gas

safest rwhp is about 3:lol1:

I know people for whom 100HP is too much. The number is not important, it's the maturity and common sense of the person who's foot is connected to the gas pedal.

I meant safest amount before the engine start to have problems

I don't think he's asking about the responsibility of power. He wants to know about the structural integrity of the engine.

I've heard around 650 should last a good while, just don't over rev it.

before production in 07 i heard one of fords test motors let go at about 660rwhp....they do test them long and hard though!

its all in your tune, if you twinscrew you can safely run 17# of boost and daily drive. It's all how hard you drive your car.

as long as its tuned properly, I would be more concerned about max boost with the right octane, not a certain power level :shrug:

Most turners set the rev limiter at 6500. Is it safe to rev it up to 6400 or 6500 RPM's?

 

[chuckstang]

No

keep the revs to 6250 max for long term durability

and were running it at 6800 rpm's......^^^^^

as long as you have a good tune. shift at 6300, don't drive like James Bond
700+ all day long- IMO.

My good friend has an 07 with 28,000 miles putting down 800 with no issues at all.

Yup thanks for the info.

Thats what I heard from a friend who works at Ford, he asked someone who worked on the 07-09 Gt 500s and he said 650 rwhp all day long and you can drive it like you stole it for hours

as long as its tuned properly, I would be more concerned about max boost with the right octane, not a certain power level :shrug:

Thanks I am gonna get a good tune on a dyno, and only run about 15lbs of boost through a whipple. I never put anything less than 93 grade in my car

Ok at that psi which blower is best. 2.9L or 3.4L Whipple. I thought the 3.4L made more whp at boost above 15psi but heard it was sluggish compared to the 2.9L at boost under 19psi?

I'd like to be able to drive every day at 17-18psi and be making more whp then anyone else. I do realize it take a little bit longer to achive max boost on a larger SC but can it really be a deal breaker in a 650whp car? If I had a larger SC I would swap pulley's for dyno days and going to the drags but not for every day as higher boost (20-21 like KB guys) I feel isnt good on the engine long term.

Can you fit a 3.4L under a stock 2010 hood w/ the K-member or does it need more? Also will a 3.4L fit under a 2010 KR style hood but keep the stock K-member?
