Tyler had kind of a shocked look on his face after the last couple runs,I don't think he gets many guys coming in with home built motors making 1100hp,especially blowing thru a modified 502 mpi system. He busted his azz for days on the dyno at about the busiest time of year for him so I can't tell everyone how much I appreciate his tuning abilitys and skill running the dyno. Bob Madera was confident we would make 1050hp,I was skeptical that we would go much over 1000 so when we made 1115 we were estatic,I think Bob is like a cam god,Smitty

Congrats, Smitty! Great numbers. Guess it's time to update your sig.

Very impressive. N/A at about 1.22HP/cid. I love to see when the peak HP and peak TQ are the same numbers. Great engine setup. How much boost were you running? Is the fuel pressure dropping off over 5000 rpm?

Very impressive #'s. Congradulations. I have just 2 words to say to you now....

BRAVO EATER

unbelievable, that is awsome..........I might have to use your brain this winter....I want to build a blower motor for the mag...I have printed and collected most of your posts, you really put a lot of info out there for us....We are real lucky to have a guy like tyler and you right here in mich....

WOW Smitty congrats. Those numbers are sick. Hope to see you on Hardy pond this summer.

Smitty congrats on the #'s ,Very impressive.Thats good #son Pump gas


Did you try above 5900rpm?It looked like it was still climbing!!

Boost 's ?

Thanks for the email

Why is fuel pressure all over the road?? fix that and getting the lambda straight should be easier

I knew when the N/A power was over 650 we were going to make some real power. Tylers support equipment( o2 sensor and fuel pressure sender ) had problems,we made a ton of pulls under boost setting the multipliers and fuel tables and we installed his runda o2 sensor in the L/H side because we weren't getting a accurate reading from the sensor,he didn't have another o2 sensor so we were reading the plugs after every run and watching the r/h sensor. The fuel pressure sender was the same way,it would go nuts and varie between 40 and 100 psi under boost,the thing is even when my voltage booster kicks in at 5psi I can't get more than 75 psi of fuel when the injectors start staying open for 7 or 8 ms,he said not to pay any attention to it because the afr's on the r/h consistantly were the same on pulls. With the 3.85 pulley after you went past the hp peak the afr;s would start going rich,he took fuel out to the point where it was getting less fuel at 5900/6000 then 5600 and it still showed down around 11-1 or less,if the fuel press had really dropped to less then 65 at that point it would start leaning out and detonating bad,Smitty

Rob,the 1057 was marathon 93 octane,we ran 80% 93 with 20% race gas for the 1115 so that wasn't truly pump gas but I run that mix when I'm going to punish it hard . As far as boost,the 4.0 pulley/1037 hp was at 10 psi at pk and 11 psi at 6000,the 3.85 pulley/1057hp was at 11 at pk and 12psi at 6000 and the 3.70/ 1115hp was at 13 psi at peak and 6000 which were really close. I am convinced that CFM's inlet adapter and my bored out throttle body are letting more air/boost into my intake because the boost #'s are higher then I have ever seen before with those same pulleys. I didn't expect to see a increase in boost however because the new cam is 10 degrees bigger then the old one so I figured it would let more boost into the motor resulting in less boost at the manifold,Smitty
