Cheers people

 

it does look much better now with these wheels,  stuff 20 inch rims, personally I think the 18 look heaps better with tyre to rim proportion

 

Will be good to see what mph I can get now as I can get a lot more power down with these

140-145mph

Looks great! Absolutely agree a bit of sidewall makes a lot of cars look heaps better.

if I set it up for drags with tall tyres and th400 and a 5000rpm stally I have no doubt 140+ would happen

 

with me shifting from 2nd to 3rd on the brink of traction I for see 130mph

What, “only 130mph” whats that going to be mid 10’s?

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

If I can do a 10.9 in manual with 4:11 on what is essentially street tyres I would be over the moon lol

 

i dont see it happening though, with the old v2 blower manual was great fun, now though it is starting to become a hand full to drive fast

 

maybe be I can fluke it on a pass some time hopefully lol

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

130mph is 10’s.

If you can pedal it, it’s got a 9in it.

This has a 9 in it all day long powerwise. Negatives are, manual and irs. Unless Pete wants to chase a drag only set up a 10.xx would be unreal.

when I own a drag car it will not be registered, it will be a drag car

 

this manta is a street car, if I ever get a defect or it gets me into to much trouble I would pull motor and chuck a basic ls combo in it and take this motor and sell blower, manifold, Intercooled and so on and use that money to fund a injected 8/71 on it and put it into something very very light for a drag car

 

untill then mental street car life

 

will get back down the strip again soon

got a new set of head gaskets coming soon along with head studs

Curious to know what head gaskets your using now and what your upgrading too Cometics?Have you got o rings?Also are you using bolts instead of studs or are you going to the bigger 1/2 inch studs in the centre?

Car looks great,should be able to put more of that power down now with those tyres.

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

Got arp head studs 12 point nuts

 

And cometic mls gaskets 0.040

<span style=”line-height: 1.5;”> </span>

<span style=”line-height: 1.5;”>Changing them because a while back i had 1 of the heads off just before changing to e85 and could see one was starting to blow out so now im onto changing them before we really screw power out of it </span>

 

Would of been 18psi and 98 with what we think is a bit to much timing from last tuner, but it seamed to be ok but i want to be sure

 

Also goin to do a tiny bit of match porting i know it needs while im there

Is match porting as critical with FI?

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

It all helps.

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

When the intake ports are out from head to manifold by about 2 mm and exhaust ports on heads are square and extractors are round I’m guessing it’s not great

Lol, yea well there is that….

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

So pulled the heads off and got the gaskets all changed

 

just st a stupid amount of work to do but it’s all done now, every cyilender had blowen out slightly

Couple pics of showing some random blow out parts, I match ported the heads to Intake manifold as they where out by around 1.5mm each side but didn’t do the exhaust ports as I’m getting a old head and want to port that and see where the water jackets are first

 

can see in the last pic just how much damage the pipes have done to the chassis rails even though there Hpc coated

 

will paint that again one day and put some heat shield there but couldn’t be stuffed at the moment lol

 

anyway ay it’s all back together so just look at a pic from the previous page as it still looks the same lol

Do u always keep the nipples on water pump blocked?

[VS 355 UTEParticipant QLD96 vs v8 ute View build HERE Member since: January 13, 2016 Posts: 141]

Your right,lot of work.Did that three times on first dodgy engine build trying different head gaskets,engine out twice also.Would be nice to have the extra head bolts.Good luck with the new tune.
