What do we have planned now then
Discussion
After the great day out Saturday its left us wanting a bit more(if you know what i mean)(which i'm very sure you do
) So here's what we're doing next:
1. Performance Pack
2. 3.9 Diff
3. Road Response
4. Full AP Racing Brakes
Need to call Roger for a price later
So what are you lot thinking on
a. My list and
b. What your gonna do to your Beasts
who was it that said modding was expensive and addictive
You were right
Funnily enough it was Col going on about it all day yesterday not me (for a change) not that i'm complaining
Drag days done our relationship the world of good

Id aim higher if I were you or sell the CV8 and get one already modded. Why pay out for brakes BTW unless your going to start track work. High spec brake fluid fully flushed through with performance pads and braided lines will surely be enough for fast road work.
That or buy mine...?
That or buy mine...?
If you only intend to go in straight lines, I would go straight for the diff, it will make the biggest difference to your times.
Then it's personal choice.
IMHO
05 CV8 brakes are competent enough for drag days, but maybe not for track days - and col said yours are brand new?
RRP is an improvement in steering feel and response, but again mainly for cornering.
Finishing off the exhaust will release a bit more power but on our levels of gas flow, is not THAT important (apart from the sound which is addictive!)
I'm going diff next.

I'm going diff next.
Even though I didnt make the track day (going to have to make sure go to next one!) my list is as follows:
Road Response Pack - in a couple of weeks
Custom Manifolds - Hopefully September
Custom Exhaust to replace aftermarket one thats on
Better air filter of some sorts
Intercooler for SC
New pulley & Re-map
Then that should be me done with the car performance wise.

Remember that your car and mine run similar HP already. The 1.5 seconds between them will be much reduced by a diff change only. I'm running 3.79, so a 3.91 will be slightly better again. Second mod would be a decent cold air intake.
Why not go all out then and get the 4.1? or is this "too" extreme for daily driving/fuel consumption?

If I wanted any more power, I would just fit another pulley and up the PSi. I would need to uprate my clutch from OEM then though.
So rear arch work and a new staggered alloy wheel and tyre package are the next things on the list.
Only other thing I want to improve on is my own reaction time - so plan to start playing Dodgeball with Wrenches and Tyre Irons in an effort to improve myself! ;-p
In my opinion, I seriosuly don't think there is much in the way of improvements to be had when uprating the rear end components of our vehicles.
To get the most from any of these "stiffening" modifications, you would have to do them all - poly bushes, Harrop diff cover, coilover suspension, etc. The lot. Otherwise, if you only did one or some of these, then the improvement would be negligible - as the areas not modified, would be your "weakest" link - letting the other uprated parts in the chain down.
It's an "all or nothing area" I'm afraid.
I won't be going down this route, until my OEM dampers are shot, then I may uprate to HSD coilovers.
Performing these "stiffening" modification will also totally ruin the good, all round, everyday ride of the vehicle - increasing road and diff noise, stiffening the vehicle up too much to the point of creating endless rattles, bumps and bangs on our roads.
From your list Mel - and due to the fact that you both drive the vehicle a lot on roads daily, use for dyno days and drag days only - no track work involved. I would forget the stiffening modifications, unless you can afford to do them all (£££££ and you can live with the change in characteristics on the car as a result of those modifications on a daily basis.
AP Racing brakes are a good upgrade, but again, expensive and unless you do track work, you will not see the benefits.
Personally, I would concentrate on the diff ratio for sure.
Cheers,
Kyle.

That's almost 150hp more than my 335hp at the wheels and only 0.3sec quicker and +5mph over the 1/4. Maybe some of the horses didn't come out to play.
As I said in the post... power is there, but traction isn't. Only running 245 wide Falken road rubber all round. Unwarmed - no burn-outs on the day.
Times achieved down the strip are not down to power of your car alone (if at all) - more down to the TRACTION ACHIEVED, driver skill and driver reaction time. We saw perfect examples of that in some very high horse power Monaro applications on Saturday at Shakey's. I have enough power, just need to put it and keep it all down.

Common misunderstanding, times are nothing to do with reaction time as the timer does not start until you do. You can sit on the line for 10 mine and still run a 12 sec quarter!However if you didnt do any burnouts, then that will have cost you a lot! Bad, bad.

Learn something every day. I thought that the reaction time was built into the total time taken to perform the 1/4 mile run.
In any case, that's great news. Just need to concentrate on improving traction then.
I laid off of the burn outs as these tyres need to last me a little while yet.
Be interesting to know if the burn outs make much difference at all. Especially on hot days such as Saturday. Did anyone do a mix of runs with and without burnouts before the start of the 1/4 mile drag?
Be interesting to know what sort of time getting your tyres properly warmed up can shave off of a run on average.

Definately! Last time I did a crap 14.6 with my one only run, no burn out. I think my 60' was like 2.3 seconds or worse.Be interesting to know if the burn outs make much difference at all.

With a burnout there is loads more traction, my best was 1.980, they say every 0.1 saved at 60' is 0.2 at the 1/4.
So thats 0.6 seconds just from better traction.
My tires were almost done when I arrived and dispite loads of burnouts every run, there is still plenty left, so its not too bad on the tires.
Drag radials should allow 1.8 or maybe 1.7's at a push. Ive seen nutters with full drag tires like Global-i's doing 1.5 and 1.6 60's which should give them a full second off the 1/4. But Martin needs to practice his burnouts and launch more
His tires were like marshmallows to touch.
Hi Mel,
3.91 is a fab upgrade on our cars, had mine done in January - since getting worse fuel eco but suspect I am enjoying the extra power. Does not make 1st gear too short which some of the VXR drivers report (due to their lower gearing in the box).
Mine is in for APs on the 10th August and already have front and rear response packs, coilovers and quick rack. I have run out of the reasonable priced upgrades and thinking about a cam and even Wormus' S/C (but still too expense for me). It is my daily driver and do molly coddle it lots.
Cheers
Steven
