Just talked to Todd, the person who has been dynoing EricBakers car, Eric went in for another dyno (dyno has been fixed) today with his car stock on the same dyno (same car same dyno). He made 263 whp and 245 wtq, thats a gain of 16 whp and 45 wtq . I am sure Eric will be in here with the dyno.

 

New headers or same as before?

 

Is that for the 250 or 350??

 

erikbaker has a 350 and it made 279/280 with the headers. I think this is a dyno done after they're removed, so without headers it's 263/245. A drop of 16 whp and 35 wtq.

 

But that was the old setup not the new one right?

 

He made 290 wtq, maybe a tad bit more than 290 even and this is with the old 350 header, the new one should up the hp and lower the tq a bit.

 

So did anyone dyno the new headers yet? OMG This is getting good! LOL I want these so bad right now!

 

Combfilter, should be getting the new set tomorrow, than it's all up to him.

 

I cant wait!!

 

I cant seem to get my scanner to work. I will find someone from the buisness center at work to do it for me. The numbers Daniel has are true 279.2/290 with the 1st gen Mazzuri headers, and 263/245 stock. I also made a second run with a K&N filter, Joe-Z pipe, and the piece of plastic that goes around the air intake in the front of the engine removed. I removed the plastic so that the engine can get more air easier. I than had 272.1/251, not bad for a filter and intake. So the final numbers are... 7.1+ HP and 39+ TQ increase with Daniel's 1st gen Mazzuri headers.
I cant wait to reinstall the headers, they just sit there, on the garage floor, mocking me. I need to see combfilters results first before I decide on what to do next. The realy good news I got today from the dyno guy was that, he thinks his dyno was going bad during my first run too. He said the numbers it showed are correct, but the placment in the RPM range is a little off. So I will be getting a free dyno when I reinstall some headers.

 

So the final numbers are with the 1gen headers?

 

Nice, this is great news!!! cant wait to see what numbers the new headers will spit out. 35-39 increase in torque is pretty amazin, i hope this number doesnt go down too much.

Daniel I hope you havnt forgotten bout us 2nd gen IS300 guys.

 

-fixed

lets not get the two prototype header versions mixed up with the mazzuri is300 headers (1st gen) and isx50 headers (2nd gen).

i'll take +10hp -5tq if you can do it daniel

 

i think he meant 1st gen headers that were made for the is350!!!

 

I was talking about the 1gen headers for the IS350
