Max17 First lake run....painful.

[Doc Harley]

TD Max17pm
Stock primary spring
Qay-70's @ 71.3
9000rpm
Dalton BLK ORG V2 @ 6/2
XS825
Boost 16.8
Detonation light came on immediately so I added boostane 1oz to 5gal.
Light off.
Pulls strong then seems to hit a brick wall @ 117mph.
Conditions are not perfect, rough. Temps warm at 32°F
Stock Sled pulls speedo 115mph all day everyday.
Is there something I can look closer at while I'm here?

 

[Pstn head]

condition of track, tension of track, or size of lugs possible ?

 

[sideshowBob]

Boost, RPM, looks good...should be performing well.
Conditions have a huge effect on top speed.
Helix?
Gearing?

 

[earthling]

If you haven't changed gearing you are probably just getting to top speed faster.

 

[rev them up]

I'm thinking get rid of the stock primary spring
I'm running ms17

Boost leak test first

Track is good, 1/4" sag, 1.25" lug

Boost, RPM, looks good...should be performing well.

Helix?
Gearing?

Not perfect but very doable. I've ran on this type of surface many times
35° helix
21/41

If you haven't changed gearing you are probably just getting to top speed faster.

Speedo numbers are going fast. Then just stops. 117mph is too low to top out 21/41???

My clutch weight to achieve rpm seems low. I was expecting to be @ 74g+
I have a Dalton BLK BRZ I could try & a Yamaha Blu Wht Blu

Are you still running the stock BOV?

 

[Doc Harley]

Boost leak test first

I'm afraid that was left behind.
Also my IAC temps were pegged.

 

[number1kyster]

21/41 should get you 124ish on the speedo.

 

[Doc Harley]

Are you still running the stock BOV?

No turbosmart, I'm not in a position to test for boost leaks, unfortunately.

 

[stgdz]

Did you trim the intake barrel clamps?

 

[number1kyster]

You are limited by the BOV. At 16.8, it should still run out of gear.

I’m surprised the stock BOV holds that high.

 

[number1kyster]

You are topping out at 24/50 speeds.

21/41 should get you 124ish on the speedo.

Unfortunately, that's not going to happen. Made the move to a flatter lake....113mph . Also it was an afterthought as it's getting dark.
Tomorrow's another day. Just kinda thought it might be clutching. Uneducated guess.
