ytzuzu Posted November 14, 2011 Share Posted November 14, 2011 I'm wondering if this has been done... Twin vgt turbo e9? Or how about a stealth brake on an e9? can these be done? I'm pretty sure the hair dryers wouldn't be terribly hard, but would the engine stand up to an exhaust brake or two if twin turboed?

ytzuzu Posted November 15, 2011 Author Share Posted November 15, 2011 Wow!! Sweet! Fullfuelo1, does the 900 indicate the h.p.? 4 turboes....2000 and 4000 hp?? hehehe... would make mole hills out of mountains for sure, but longevity?? I'm wondering if say that 900 hp twin turbo would work in a truck? And for how long? Still curious about an e9 with stealth brakes. Would the heads hold up? bottom end?

Mack Doctor Jr. Posted November 16, 2011 Share Posted November 16, 2011 Jr himself has a couple of his own road trucks with 1,000 hp that go down the road every day. The stock heads will not hold up to that type of hp on a daily basis. The only way is to do what he did. And that is to buy heads from Dale Francise. He has 3 different types, stock heads ( which have the valve seats pressed in to 10,000 psi.) ( stock from Mack is only 5,000 psi which is why they cant handle that much hp) Dales 2nd set is a hot stock ( a little porting and bigger springs), his third is full on high performance turning up to 5500 rpm.So back to the topic is u need heads first thats 5 grand or so, an inline fuel pump from Jr's pump man and laser cut injectors and a Holset turbo that he recommends for the set up and bump the timing a little and there you have it.....

I got many people here interested on tunning MACK E9 V8 for Drag Race so we can send the 8V92 crew home. It is time for the MACK PACK ATTACK!!!!!

Mack Doctor Jr. Posted November 17, 2011 Share Posted November 17, 2011 A friend of mine was telling me about JR's trucks. He gets 5 to 5.5.... If u keep the boost under 20 u will get 8 mpg..
