Ok, so we had here in Estonia, Tartu(second biggest city) Speedest Drag Comp.
The track is slippery and full of dirt so times were terrible.
I must admit I lost all races.
Best time was 14,9 with 60' 2.34. top speed 94.76
Improvement with last year same track 0,2 s. and 60' was then 2.39.
Also it is replaced the y pipe from already last year and you can feel it.
I was thinking to put also OBX headers.
Now I had in my car new clutch Exedy Stage1 and custom exhaust with Tanabe Hyper Muffler. They advertised it is quiet. Dream on. Screams like crowd of wolves. And I had this year MT Street slicks 24/9/15 and still no improvement to last year with standard tyres Goodyear Optigrip 15 inch.
I am dessepointed.
Of course my oponent was BMW 540 5speed with 311 hp and also MT slicks
with M5 clutch. He had time of 13,7
Can somebody explain that?

Yeah sounds like that track sucks. 2.3 on slicks is really bad. Im sure if you went to a better track you'll see better numbers. Good job though.

 

Thanks
what you think. whis headers are better OBX or Cattman for 4th. gen.
I kind like OBX, they have distinctive design I mean headers and Y tipe together.
How much hp I should pick up and in what revs?
Thanks !

 

They will give you pretty much the same results in terms of the power you gain. But cattman's product will not only be alot easier to install, but it will also last you alot longer and will also hold its value when you're ready to sell them.
