So, are you running a blow-off valve? I don't see one

As posted in all the other threads no blow off valve. Screw that rubbish.

Twin turbos? Its an idea.

 

wouldn't this change the efficiency of the twin turbo.. i.e capable of more power...reliably?

Most detailed Zoom article ever.

 

When you said your running 2 degrees leading timing. Is that 2 degrees across the whole powerband or do you increase it a bit at high RPM past peak torque? And what type of split you running at such a high pressure and with such retarded leading ignition.

2 degrees to the redline.

8 degrees split.

the engine didnt need any more timing up top. it held very flat and i attribute that purely to porting.

 

Oh boy.

 

8 split eh. Oh dear, not sure what to say . I thought I was being aggressive with my 11 split at 20 psi but then again 2 degrees leading... My trailing is firing before your leading lol. Gonna crank the boost up this year and experiment some more. Good thing the billet 6765 is a high boost turbo

I'm jealous of your set up..

 

Nothing to be jealous of. It is nothing special.

 

Thought i would update this thread.

Car ran 11.8@ 139mph

It is not a full power pass and i reckon their is atleast another 8-12mph in it.

Their was around a 1.5 seconds between each gear shift.

The gearbox is out and im changing some clearences on the clutch and were going to have another go.

The reason for such a **** time is the 2.3 second 60 footer. Ill be fixing that next time.

I only got one pass for the night as the gearbox was not playing ball.

Car looks like its capable of a low 10 high 9 at 145-150mph from all the data i got on the day.

 

so if i go to the track i should be able to do at least 140 on the trap speed

 

I guess. You will find out when you race it.

My car weighs 2740 pounds.

 

For sure. You can cut almost 2 seconds off that time with a perfect 60ft and good driving.

 

Hope we can see some vids soon

 

Did you have the boost turned down? You said is wasn't a full power run? Is that weight with driver or without?

 

Quick Question,how is your engine mounted? are you using the front engine cover type mount? Just curious.

Thanks.

 

Front engine mounted.


It was on around 650rwhp and it wasnt a full pass in the sense that couldnt shift gears and their was huge delays between each gear.

 

Many Thanks..

 

wow , that's awsome man.. i hope to make those number's one of these day's

 

i hope you can get a little more to reach me lol

 

Dont worry. My drag car will be going soon and youll have to be doing the catching up soon.

GT55141R

Billet 106mm comp wheel lovin it.

 

LMAO YOU gotta post pics when you finish

 

I think everyone else in the rotary world has catching up to do on straight pump gasoline, not 85% alcohol mixtures.

 

same old stuff,, how fast you go is how much money you spend.

I know we heard that before.
