went on the dyno today made 450 whp and 376 lb tq

btw its very loud!

I am very very happy with the results 450 is what i wanted! And the tune is amazing thank you blow by racing you guys are amazing!

 

Nice!!! Blower in the future?

 

What kind of dyno? Did you dyno it after each mod to see where the gains came from?

Nice choice of options! I am ordering a SGM GT premium TP this weekend - cant wait!

 

also curious to know what kind of dyno. What kind of increase over previous setup?

 

looks like the long tubes gave you a bump over the rest of the dyno runs i've seen, any chance you could upload a shot of the dyno graph? congrats by the way, those are great numbers! i'd be curious to see what kind of 60 foot and 1/4 mile e.t.'s you'd get.

 

i believe BBR uses a dynojet, i will post the graphs and pics tomorrow. I am really happy with 450 whp seems to be the kooks headers are making more power than the others.

 

Need to see base #'s from the same dyno to see what you gained. Every dyno is different some read higher than others. Have not seen any 5.0 with your mods make 450. Take it to the track and get some trap speeds to see if you are really making that power.

 

I've got almost the same setup. Kooks ftw. My Dyno numbers are in my sig. Enjoy trying to hook up! I just added lca/uca/adj panhard and it fixes my issues. Even faster now!

 

Track her yet?

 

ok guys here is the article on my car as promised today! we did one other pull that made 450 whp however they didn't want show that one because the graph didn't look to good towards the end because my car was a little hot on that pull.

More on the BBR tune please!!!

 

BBR has always had generous dynos..... I will say congrats to the OP anyhow its a beautiful car and I bet it runs strong no matter the numbers.

 

Great numbers , congratulations

 

Very nice, I learn something everyday here, I didn't know the headers are that close to the starter, tight fit!!

 

Sure does sound mean! How is it inside the cabin?

...and when are you getting the blower?!?! :-)

 

very quiet in the cabin unless the windows are down and your getting on it. But cruising in 6th sounds stock no drone

 

Conflicting info here. You state 1 3/4 and BBR states 1 7/8. Plus the graphs list different cars. Something doesn't jive.

 

yes they were 1 3/4 headers not 7/8 i guess he made a mistake. The graphs are correct, i am Dean in the file name the one that shows 447 whp, the other one was posted accidentally there must have been a little mix up because Justin the name in the other one was actually there watching my car be dynoed and he had the same mods as me in his car before we added the boss manifold and headers in my car and made almost identical numbers. Good catch! we it will be fixed.

 

I think the 1 3/4 were a good choice. Plus I've seen multiple guys state the 1 7/8 were a nightmare to install. It's close even with the 1 3/4.

 

Kooks sound almost as good as stainless works
