VS Manta #218

Yeah 1/4 times would be a heap better certainly improve the 2.5 second 60 foot times or what ever it was

 

couldnt even get full throttle till 4th gear last time

 

so I’m goin to build a new diff, the current 4:11 diff is goin into the Monaro and goin to try maybe 3.7 with a true track and keep the harrop cover in the manta, goim to build this diff my self as well

 

if I like it will keep it if not will just get 4:11 gears and swap it over to that

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

So got back into it this afternoon

 

have now fitted a new m80 diff with 3.7 gears and true trac and fitted my old m80 with 4.11 into my Monaro

 

Did a run and was 420 rwkw at around 6000rpm and fuel system on the limit

 

bumped up fuel pressure 5psi and still went around the 420rwkw but was breaking down top end

 

closed plug gaps from 1mm down to 0.8mm did a run and she instently jumped up to 468rwkw at 6500rpm and again on the limit of Fuel system and did this on 13.5 psi of boost and 16 degrees timing

 

a gain of 48rwkw simply by closing up the gap

 

anyway 100% certin I have maxed the injectors now and with power still on a upwards climb and should keep goin to 6800rpm we excepted defeat and am getting some bigger injectors

 

also fryed up the clutch doin a celebration 2nd gear burnout so up for a new clutch plate as well and will try the ceramic one over the organic as it’s rated to 450rwkw and not 400 like  the organic

Seriously epic, great stuff, incredible difference by just closing the plug gap, I wonder what the theory is behind that gain??  Nice torque curve and linear power delivery too.  Bummer about the clutch, tbh its one of the reasons I don’t pan on going manual, I don’t hear of too many people holding your sort of power with any clutch that’s actually driveable on the street unless you have legs like Arnie.  So are you planning on taking it back out to the drag, would have to run close to a 9 now wouldn’t it if it hooked up?

Get a mantic twin plate and never look back. With handle the power easily and they are really nice to drive.

[ImmortalityParticipant 97 HSV Senator 185i 02 VX L67 Calais View build HERE Member since: August 31, 2015 Posts: 535]

^^^  Agreed. a decent twin plate clutch would do the job.

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

A good twin plate will happen one day but for now I’m just goin to get a cerametalic plate for my current clutch

 

only $350-$400 for a plate and is rated to 450rwkw

 

my current clutch has been great rated at 400rwkw with a organic plate

 

yes Gary I will be takin it down the strip soon but don’t see my self even getting a 10 second pass in it been manual, if I set it up for strip year 9s fearly easy I wreckin

The ceramic single will be more harsh then the Mantic Twin.

I do totally agree but It’s more a cost thing a the moment

 

it’s coming into perfect driving weather and already up for $1800 for a set of injector dynamic injectors and dont have another $2500 o top of that for the clutch right now, plus the Monaro is getting a cam in a couple weeks as well so funds are getting hammered

 

so will take the cheaper option that will get me goin through the winter then later on when coin is flowing nicer again will look at options

 

plus will be doin some drags this winter and I will go all spooky of the line if I spend big dollars on a clutch where the cheaper just replace a clutch plate option I won’t care to much about it

 

twin plate will happen just not right now

Yea get that, do whats easiest/cheapest at the moment so you can enjoy it.  Not that difficult for you to swap it out later given everyhting else you have done.  You are starting to get into the territory where putting a stronger clutch may put load further own the drive train, but that’s all part of the deal I guess. But imo, to reliably hold 800hp on a streeter the clutch pedal will be firm and a pita if your stuck in traffic, its just how it is, everything becomes a compromise.  Awesome power though, love to go for squirt in it one day…

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

Yeah Gary’s that’s exactly right

 

turns out it’s been nearly 5 years since I brought the clutch and it’s done around 4000km now

 

mal is looking for 8 or 10 point cushion button plate I can just throw into it witch will hold even more power then the old plate or I can just buy another organic plate $300 witch is cheap as

 

to me spending something like $2700+ on twin plate set up just isnt worth it at the moment when I have this solution for now, plus if I was to spend that type of money honestly I would probley look towards a 4l80e instead and sell my 6speed set up and I  just not ready for that yet

 

the car is halling ass at the moment that’s for sure

 

anyone got any suggestions on injectors in the 1300cc range and e85 compatible, preferably ev14 but doesn’t really matter, could change the plugs on loom if there Bosch style ?

[ImmortalityParticipant 97 HSV Senator 185i 02 VX L67 Calais View build HERE Member since: August 31, 2015 Posts: 535]

Thought you were going with Injector Dynamics injectors?

[cava454Moderator 93 VR BT1 View build HERE Member since: February 20, 2015 Posts: 2 390]

>Suss a set of Bosch 1600’s.

>I can’t justify the price difference between the ID’s and Bosch

I was goin injector dynamics till I seen 1300-1600 are $2000+

 

if i I can find someone with a set of the injector dynamics 1050x and flow them to see what they actually flow then I would get them at $1000 or so

 

I’m just having trust issues after my current 1000cc only flow 780 or so cc at 43.5 psi

 

if the ID do flow 1065cc at 43.5psi then they would suit me perfictly and I would have no problem paying $1100 or so for them but I’m having trouble believing any injectors advertised flow rate

 

and I’m a little with cava on can not justify the price difference

[ImmortalityParticipant 97 HSV Senator 185i 02 VX L67 Calais View build HERE Member since: August 31, 2015 Posts: 535]

I would expect ID flow rates would be accurate as that is what they are known for.  Best bet would be to contact them and see what they say.

[cava454Moderator 93 VR BT1 View build HERE Member since: February 20, 2015 Posts: 2 390]

I’ll prob get a set of 1300’s. As at 70psicthey actaully flow 1700cc.

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

I would of expected Bosch flow rates to be accurate as well but they are way off, I was extremely supprised at how low they actually flowed and don’t know how they can be advertised as 1000cc when they are not even 80% of that

 

yeah I will keep searching, Thing is 1300cc  injector dynamics cost more then 2 arms and a leg and I don’t know of any other 1300cc injectors that even exist

 

and the bosch 1650cc ones are $210 each so $1680 a set of 8 witch is still pretty pricey especially when can get Bosch 2200cc ones for like $60-$80 each but don’t know what they will be like down low

SADly when you get to that level. It’s just one of those shitty things that has to be done

I forked out for the ID;s after reading lots of pros and cons.  Fwiw my tuner hadn’t had much experience with them before and was skeptical.  After tuning mine he was impressed with the info/data that comes with them compared to the straight Bosch, he liked them.  I am not up to speed with all the stuff in the ECU but you may be as to what he’s actually talking about.  Imo you get what you pay for, but yes often the best comes at a premium.  Surely a car at this level needs the best (again imo).  Might be best to speak to your tuner on what he thinks?

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

Gary you sound be the best bloke in the world and pull your ID injectors out and get them flowed for me to see how there numbers compare to what is advertised

 

give you a drive if my car if your ever up this way if you do so

[cava454Moderator 93 VR BT1 View build HERE Member since: February 20, 2015 Posts: 2 390]

Yeah do it gary. And after I’ve had a drive of Petes car also I’ll convince him to let you too.
