is that with GM ls3 block ??

 

got the motor in last night, need to wire up the holley hp,put on the turbo's
and get it starter this weekend!!!!

 

Yes. And now it has a stock crank so cubes are down to around 380ci.

Here's the motor on the kmember ready to go back in.



In the car.



Here is a picture of the stock modified cluster with the Holley programmable gauges in it. This turned out to be a great idea that one of our Ford buddies came up with.

 

Which k member is that y'all are running?

 

bmr turbo k-member!!!

 

Sweet! That's what I just ordered and I plan on doing a twin turbo build.

 

Hey Carlos what do you think about that Holley EFI ECU?

 

Should know more in the next few days. Steve is wiring it up in Joe's car as I type this.

 

What would it cost for hot side and cold side minus turbos?

 

20k later ... on easy street !!

BBC pt106.... sup?

 

Carefull, He'll come out and beat up on that BBC. Your gonna need another screw. LOL

 

pffftttt......

 

If you don't mind me asking, what brand pistons and rods you all went with on the stock cube setup now? I'm wanting to build a stock cubed forged ls3 for boost as well, but didn't know what companies offered forged pistons for that bore...

Are they Wiseco? Or is there even Wiseco forged pistons available for the LS3?

 

Hot side minus turbos is just the exh manifolds and the 2 pipes that the turbo and wg attach too. I'd say you could get it done for $600-$800 easy including all the flanges.

 

This is a mullet free work place.

 

cars done, took it to the track on wed.ran on wastegate's i can only get 4lbs
on the springs no two step wasn't hook up yet left on the trans brake built no boost leaving went 10.4 at 130 not bad on 4lbs!!!!!

 

hmmm wander why there was no boost? but your right thats rocking for 4 PSI!! hahah

 

wow, that is exciting for only 4 psi boost. are you sure there are springs in the wastegate?
sounds like there might not be springs in them at all.

ps. just looking at your old times NA, it looks like it picked up nothing over the NA setup. what would you attribute this to?

 

oh, never mind I see that the stock crank dropped cubic inches from 416 to 380 or so. not bad at all.

 

Went back out today. Still no 2 step. Wiring guy is slacking. Car went 10.34,10.42,10.38 all at 130.XX. Really soft 60 due to there being no boost on the tbrake and the full 4 psi doesn't arrive until right at the 60'.

As to why there is no boost on the transbrake, He is running 2 44mm wastegates which is way more wastegate than he needs. You gotta remember that wastegates are mechanical devices (specially w/o boost controller and CO2) so they are not an ON/OFF type thing. As you start building exhaust pressure, the wastegate will start to crack open. More so with a really soft spring. Add the fact that the WG 's are way big and it just takes them cracking open just a little bit to bleed off alot of pressure. If he put in the 8 psi spring, I would bet that he would have atleast 1-2 psi by the 4K RPM that he is launching. With this soft a spring, the 2 step will likely only give him 1-2 psi anyways so the answer is boost control + CO2 which will be coming very soon.

The main thing right now is just make sure that everything is working good. The new Holley EFI system is an absolute dream to tune on and the closed loop fueling holds target AFR VERY well all the way thru the passes without much tuning on my part. It also learns on each pass so that it has to make less corrections each time.

Another thing is that everything is setup way conservative. I'm sure that with his current compression and E85 at this boost level, we could be hitting it with 28-30* but it's only got 24* and the AFR is at 11.5 on a gas scale.

Joe's been pretty unlucky for the last couple of years so we are taking it slow and double checking everything to try and change his luck. LOL
