BA GT Finally hit the dyno

[ford_racing_8]

Oh well,Theres always going to be arguments over dyno figures.

This is true, Every dyno is going to give me a different figure wether its higher or lower, to be hounest i thought this was around right only through some of the research i did ages back when i first got it and i should of mentioned it has a herrod stainless cat back on it aswell not that it would make much of a difference.

In saying that it seemed fairly accurate with the other cars on the day that i saw, regardless im happy with the figure.

Next dyno day il throw it on a different dyno and throw up the sheet, see what happends.

tristan made 246rwkw through and auto ba xr8 with just bluepower airbox.

as far as i was told bluepower told him a tune would only gain him some mid range and nearly nothing on the end figure.
chris from bluepower says the factory v8 tune's are fairly aggrsive factory so there isnt much in them.

good figure mate, but i dont think ull get anywhere near ur 300rwkw goal without big dollars and if u are going to try then please do oil pump gears before ANYTHING else.
these boss motors are notorious for shitting them when rev'd hard.
cheers josh.

[ford_racing_8]

No one seems to have faith in the Boss motors, I've seen one hit close to 300 unopened so I think its reachable.
The only way to know 100% is to get a tune and maybe a few add on upgrades and see how I go.

Next thing is calder, can't argue a Quarter mile figure

I wish I made 246rwkw it was actually 238rwkw and I also had a cat back exhaust.

Defiantly do an oil pump if your going to continue to moddify it, also in not sure if it was just the early xr8's but the timing chain tensioners are crap and need to be replaced with decent one's they are prone to break up.

There is plenty of 300rwkw GT's out there but it's not cheap cams's are a good 2k plus. I know of a GT-P with 320rwkw it's has cams's full herrod exhaust Bluepower intake under drives and a 4speed auto.

The 5 speed is not that bad I believe a very similar one when in the T3 T-Series as well, there are plenty of kenne bell blown 5 speeds around and they all seem to survive.

A nice thing to do is the oil air seprators from Herrod you can get the from Bluepower also, it stops the oil being sucked into the intake as these engines are prone to doing this and oil sitting in the plenum.

It will make a difference giving it more mid range its not all about peak power, which is normally 4th gear at close on rev limit, you lucky to ever see that happen unless you on a track. Mid range power will be very useful, a tune may also help in you fuel consumption, my BA XR8 was terrible on fuel 300km out of a tank max, now with the FG XR8 it's much much better on fuel.

It's a great car mate!

[SVT8]

I remember this on cruise for chairty . Dumping clutch in the tunnel haha, wasnt there some bloke taking video footage from your car?

We got 228rwk on the old mans bf gt, added a bluepower air intake and jumped to 240rwk on an auto. Bluepower were saying a healthy boss 290 is between 220-245rwk, the ones around the 240rwk mark were all manuals.

Spot on

[ford_racing_8]

Thanks for the information BLKPHN, definetly something to look into, its been recommended by a few ppl now. How much is normally involved in changing the oil pump in these?? I have heard they arent to strong, same as the timing chain tensioner, plastic in the series 1. My mates XR8 has horrible rattle when he first starts it.

And yes that was me in the tunnel on the cruise for charity, seemed like a good idea at the time til i thought about it lol. My goofy mate was taking footage of everything but the fun stuff....

When he said a healthy boss pulls 220-245, was that stock or with the air intake???

[braad]

Nice result. Its in top nic too. My uncle picked one up with similar km's 6 months ago. Awesome cars

[sikwags_218]

A mate of mine has a devil R. Special edition GT and he is getting 260rwkw, with airbox, cams, oil pump gears, full exhaust and tune through a 4sp auto. He has since done the throttle body so that will be interesting to see what it puts it up to.
Nice car anyways man

thats pretty low for all that work done, you think the Devil R stickers & badges would add atleast 30 more rwkw

My old BA still holds the unopened record and that was only making 280 rwkw although it was an auto, pretty much had everything bolt on done to it except for bolt on boost
Had 2 different tuners tunes, 1 being mine and both made the same power with the same mods. 300 unopened would be a stretch, a few have gone 300 with cams and all the bolt on mods, but again as mentioned, a different dyno may give a higher figure.

[lukeh]

no faith in the boss guys!

Its like anything, you get clagger's and you get healthy ones.....you guys struggling to make power with work clearly have the clagger's!
My dads 6 Speed manual GT with almost 200,000k's is pulling 300+ and isn't heavily worked?
323rwkw and that is with CAI, mild cam's and a tune.
First tune with just CAI he pulled 286rwkw then with a re-tune at a different place hit 296rwkw.....he wanted 300 so then came the cams and its now well over 300rwkw.
It's all a reputation, its like everyone thinking 6.0L'ers are monsters, in my line of work I get to drive a wide variety of cars and the majority of 6L'ers ive driven couldn't pull the skin off a hotdog.....much like boss motors, plenty of clagger's around but you do get the good ones!
When he gets back from overseas il get him to pull out the dyno sheets for all you non believers.

I can vouch for jacks car too, out of our group of friends cars, VE SS's, VY SS, BA XR8, a modded R34 GTS-T and his missus' xr turbs it is by far the quickest, 260rwkw is more than believable

[Parfrey]

I'm pretty sure it'd be more like you get the happy dyno's and the sad ones

If your happy with how the car goes thats the main thing! its only a number.

[ford_racing_8]

Don't get me wrong, I'm not arguing with anyone here, everyone has there own opinions, some ppl on here have good figures for what they have, others not so good, I'm happy with the figure and for what I saw on the day the Dyno was not over reading unless it decided to with just my car, when I run it il post up the slip.

has he raced it and if so what did it run?
I'd like to think mine was a good one as no one has beaten my times unopened from about 4 years ago and it did not go anywhere near 300

[ford_racing_8]

What did yours run down the quarter

[lukeh]

Nah never hit the strip, only gets used for road rallys, hill climbs and the like and has done best in class a few times

[ratter]

What did yours run down the quarter

best was 11.76 but was on slicks on that run, I have some posts about it on another forum

Would be great seeing that take it to some of the other cars

[SVT8]

Yeh that was for stock. The boss engines also free up a bit of power as they get on with age, so i was told. There a bit all over the joint, i mean i have seen a few with full bolt on's only make around 260rwk untill they get a tune bumping it to around 290rwk. Others may get around 280rwk with bolt ons and only gain 10rwk with a tune.

That is a QUICK unopened/NA boss!

You should make a thread

[ratter]

Thanks mate, but do not have that car anymore and this forum is about boosted cars

I have heard they arent to strong, same as the timing chain tensioner, plastic in the series 1. My mates XR8 has horrible rattle when he first starts it.

No problems,

The oil pumps are a pretty big job, especially with all the chain tensioners and everything in the way, the timing cover has to come off and dismantle the front of the engine, when I do mine I'm just going to hand it to Bluepower to do, at least it will be done right and will be peace of mind.

The plastic chain tensioners are horrible on start up, my old BA XR8 had the same noise. It's the same deal to fix the issue, why did ford put them in I have no idea.

The Bluepower Air box seems expensive however it is well worth it even just for the noise it makes, it will work better in a BA BF than the FG as they have the lower headlight intake area. I gained a increase of 29rwkw in the BA I know it sound amazing difference but it must have just been a freak, it sat on the dyno while we changed it over so it didn't even move from it spot between testing. Fuel economy is increased also. The plastic ones you can get heat soak to much and have a negative effect as it holds in the hot air not dissipate it, aluminum is just as bad as it soak in heat really quickly and retains it (think a heat sink on electrical components).

Getting those oil seprators will be beneficial, once that Boss is singing it will be sucking in huge amounts of air along with all the oil vapor. I was at Bluepower once and watched a GT gain 15rwkw from cleaning out the intake plenum of all the oil that was sucked in from the pcv valves.

You can make 300 with cams and a decent exhaust, obviously with most the bolt on's. And being the manual is defiantly achievable. Choosing the right exhaust is worth considering also. Bigger doesn't always mean better, big headers may give a lower midrange and doughy feel down low, as the airspeed decreased due to the large volume of the header. Also consider as the exhaust gas cools it becomes denser and airspeed will decrease again.

Most cars here AREN'T boosted. If you have pics smack them up mate!

[ratter]

here's one from Heathcote

[[Sterling]]

I dony believe your power figure. Please provide slip times to proove it on the Internet.

[ford_racing_8]

Whos power figure? Whos slip times? Havnt run mine yet so can post up times.

[Mr_4.0]

Think he was joking :-/
