Effects of modifications boss260!

[Quadcams]

One of the LS1 guys did this on another forum, it was quiet interesting and helpfull so I thought I'd shed some light on my mods sofar and the results for my Boss260.

Stage1

13.834@101.19mph 60' 2.182 street tyres (dunlop 9000)


Mods- pacemaker hedders difilipo X pipe redback 2 1/2 dual, herrod helix, BPT underdrives, SS cai, edit tuned by a Sydney tuner (234rwkw).
Race weight- 1862kg (inc driver)

That was the best i could get out of her on street tyres still a bit green in the launch department.

stage2

13.581@102.21mph 60' 2.025

New mods- MT ET streets, mal wood clutch stage2.
Race weight-1862kg (inc driver)

New tyres helps with 60' times hence dropping my ET by .25 also new clutch helped to.

Stage3

13.361@102.91mph 60' 2.036 (NB: trap speeds were out at WSID on this day corrected to 105.6mph
Race weight-1862kg(inc driver)

New mods- generic tune by Bluepower/xtreme (236rwkw), GM ripshift.

The generic tune had similar power to old tune but showed much better 1/2 track times and mph than previous tune (more torque) also GM ripshift made me more consistant on gear changes.

Stage4

13.271@106.16 60' 1.966

New mods- custom tune done by chris from Bluepower
Race weight-1862kg (inc driver)
Custom tune didnt make a huge difference as air quality was not as good as when I did the 13.3 improvement was mainly due to better launch (1.966 60') but definate improvement from seat of pants feel though my ecconmy improved after custom tune.

Stage5

12.983@105.79mph 60' 1.817

New mods- 4.10 diff gears, remove tailgate.
Race weight-1831kg (inc driver)

With diff gears most of the gain was in my 60' (1.817) due to the extra torque from the 4.1's, air quality was ok around 1200ft RA.

Stage6

New mods- Bluepower cai, retune by chris (252rwkw), slicks/frontrunners less 51kg.
Race weight- 1780kg (inc driver)
No PB as yet due to hot summer temps the RA's have been through the roof but showing good potential for possible 12.8 or less. Heathcote 28th jan did a 13.14 with a 3184ft RA, am going to wait till cooler weather to see what she got in her, will keep you posted.

If anyone has comments of info to add about there boss etc go right ahead, I only did this so we can have more fast fords at the strip.
