Cheers, Gerry

So no other forum members interested in the Sunday street meet this weekend?  I am taking my SLR and a few mates are bringing their cars too.  Be good to see so some other torry nuts have a go :-)

Got big block 1.6 Getz..race ya for pinks.

 

Sle getting a modded tank + other work

[Redslur]

You might win mate LOL

 

Used to get good turn outs to the drags from forum members but it seems everyone is too busy nowadays...or too slack...

[gtrboyy]

It's even got fancy traction control...

 

Yeah know what you mean think it's more to do with changing car culture & age related.

 

Only just getting back into cars myself,most of the revheads I knew growing up are sold out,maybe 1 or 2 with still projects unlikely they'll ever finish.

 

Just not sure about damn rain otherwise keen for a torrie fix.

So where were you all????  Had another great day thrashing the LH. I was pleasantly surprised at my replacement 355 still managing mid 11's with a best off 11.5 @ 116 MPH.  Not bad for a 100 HP less than my big engine and yet more driveable and street friendly and only running half a second slower :-) Go Gerry engineering LOL...

I was across the road at the GP circuit where the (Barry Sheene) International Festival of Speed bike meet was being held, does that count?

Lurking hey mate :-)

[LXCHEV]

Sweet time, congrats mate. Especially for that MPH too.

Can you give us a quick spec rundown on that engine, and what driveline are you running in the car now?

[Redslur]

Cheers Brett. It surprised me too but got out of the hole extremely well. I built the engine to make it more street friendly funnily enough. Changed the diff gears and conveter to match the engine specs.  Worked really well together and surprised quite a few people.  Was getting consistent 1.6 60 Ft times too.

 

COME 355 stroker

10.7:1 comp

Mild port VN heads

Crane F280 solid cam (244-248 @ 50)

TP dual plain high rise manifold

750 Street HP DP

450 FWHP

 

T350 fully manualised

4K TCE converter

9 inch 3.5 gears

ET street radials 235/60/15.

 

The car with me in it prior to my run weighed 1478kgs.

Man even though I'm running a 383 SBC, our setups are unbelievably similar.

Mine weighs in at around 1480kg with me in it. Makes around the same power ~450ish HP.
3200 stall (no doubt hurting me a bit), with 3.7's.

Engine wise, I'm running a smaller hydro roller (236-242 @ 0.050). Dual plane, Tri-y's, 750 HP Ultra, 10.5 comp.

On street rubber, I managed 11.82 @ 116MPH. Could only 60 foot around 1.7.

With a previous combo on ET Street Radials, it's gone 1.62 60 foot and 11.77 @ 115.

I enjoy trying to extract the max out of conservative combo's. All going to plan, I should be up at Heathcote racing this weekend.

I'm super impressed with your results. Do you reckon there's any more in it, or you've maxed it out?

[Redslur]

With a colder air temp and slicks it might go a 11.3 but at the end of the day, the car is pretty much perfectly set up. Like you said, 11.5 @116MPH is pretty much at its potential. I was only expecting a high 11 at best but it hooked up so well it got me the better times. I based most of my calculations on my last injected stroker which had similar power but I could only get it running 11.9's.  But the converter and gearing let it down I think. Sometimes people over think diff gears and go for too low a ratio and it doesn't complement the cam. 3.5s are awesome for a mid range powered engine. My big engine had 550+ hp, a 5500 converter and 4:11's gear and only just cracked a 10 second pass. So this little sucker is not much slower really.  

 

If you went a 4000k converter and 3.5 gears, I reckon you would improve too.

 

I am not going to chase better times.  This car has seen the strip enough now and it too nice a car to beat up.  So will more than likely reassemble my big engine and put it in something lighter and have some fun :-).  Thanks for your interest bud!

[LXCHEV]

Great stuff. Enjoy it mate. Streeters rule!

[gtrboyy]

Similar thoughts & engine too it seems....I'd be happy for mine to go mid to high 11's on street rubber then drive home although it's not really highway friendly with 4.5k stally,4.5 gears & 27-28 inch street tyre.

 

Don't want to weigh vh sle now if yours are 1470kgs

[Redslur]

Yeah mine is a bit fat but has a chassis kit and had half a tank of fuel and I weigh about 92kgs.  So the car would have been around 1360kgs in a reak world.  The VH would be very similar at a guess. 

 

It is worth weighing them prior to a run to get a good idea of what HP your engine has using those HP darg time calcualtors. I worked my engine ouit to be about 450 FWHP.

[gtrboyy]

Suspect vh is heavy with optioned luxury gear in it being sle model then add 9",thick steel tubs,mounting brackets,coil-overs etc & me (130kgs)

 

Think local tip/recyclers banned me...have weighed several cars there haha

[LXCHEV]

Yeah my car could go on a diet, but it has a lot of heavy items: TH350, 9" rear, chassis kit etc.

PS. Got back to the drag strip last weekend, pushed a bit hard and my good luck ran out. After 2 decades of punishing my car, I launched hard and ripped a trailing arm mount off the diff housing. First time ever I had to tow the car home, bugger!

[Redslur]

That is called striving for the ultimate pass :-) Could have been worse mate....fix her up and have another crack.
