Anytime!

For me, its been the journey. Numbers are numbers. I'm more interested in the overall changes and what they do.

Gonna be fun to find out!

Took the car out last night -- running really well for the base tune -- I noticed there is power on tap -- really different from before -- I can ease into it and you can just feel it wanting to let loose.

I can't wait to see what she does..'

I know its not a forged bottom end, but, that is in the future -- have many options, but may go with a custom forged short block depending on how this does on the dyno.

Transmission is doing well so far, but I have that budgeted also.

1 week from tomorrow!

BTR LS3 .660 Valve Springs -- Check Height

Couple of days and dyno time!

In the mean time, I'm working out getting my valve springs setup.

Just in case some of you are not aware, you do need to know what 'spring' height is needed.

Here is a great website to help out:

http://kmotion.biz/instht.htm

For me, I have the BTR .660 spring set:

https://www.briantooleyracing.com/66...l-springs.html

So, from this site, I needed to know:

Installed spring height: 1.780
Coil Bind: 1.070

Next, I need to know my valve lift from the cam -- NOT the lobe lift. I got that from my cam's card:



Look for VALVE LIFT and choose the higher number (.639 in my case).

With this information, I can now get my 'minimum' height needed to avoid coil bind and apply the right amount of pressure:

1.070 (coil bind) + .060 (minimum coil bind clearance) + .639 (valve lift).

Add those up and you get 1.769 as the 'minimum' height the spring needs to be once installed. Using the BTR setting of 1.780 and I now have a better coil bind clearance of .071. I'm using BTR's coil height as my cam did not come with a suggested coil height. BTR states these are a direct drop in, but I'll still want to check. I believe a 0.020 +- is an acceptable range to work in.

If the range is 'too' long (say > 1.800), I would need to 'shim' under the valve spring locator, too short, and, well, heads come off and you need to have them worked on...

From what I've seen, .060 to .100 is approximate minimum coil bind clearance to shoot for.

BTW, to get VALVE LIFT, multiply rocker ratio by lobe lift (1.7 * .37598) = .639166 or .63917...

Some supporting info:

http://www.superchevy.com/how-to/eng...-valvesprings/

http://www.superchevy.com/how-to/eng...spring-height/

http://www.superchevy.com/how-to/148...iables-basics/

Knowing this helps me make sure when I do the new springs, retainers, keepers. seals, and rocker/trunnions, I'll be able to confirm my updates -- yes, I already have the tools ;o)

The 'blower' friendly cam GPI did for me (VVT) is .628/.621 and 118 LSA - Cam Motion core too!. I'm saving that for the forged short block ;o) ...

Here are those specs:



Info about the 315612 core (its a 5150 standard core for VVT -- same as what GM uses -- since the core #'s matched -- assuming that is the case):

http://camshaftmachine.com/wp-conten...2015-01-30.pdf

search for part no 315612

GPI Prep Day!

Alright! One more day!

Before I leave, I checked in with Ryan about my choice of plugs.

I was running TR7IX, and was looking to goto TR8IX (I have them), but after discussing with Ryan, I installed these:







Ryan suggested I go with these and, since I trust him, installed them. They are 1 step cooler (8) and are Gapped to .030 (that is what they were in the box) and did them in about 45 minutes. Note, the TR7IX is a iridium resistor/projected tip, and the R5671A-8 are not resistor/not projected tip, and copper...

Ready to see what she'll do!

Ryan and I talked today -- he's going to do the cold tune first, so, that means tomorrow morning @ 7:00 AM Central!

Spoke about short blocks etc... getting excited!

Jokerz Blower for the WIN!

Numbers are in!

Let me setup what we did:

Ryan actually drove the car first, did an initial setup, then brought the car back into the bay to do 2 things:

Re-install my exhaust (the damn clamps didn't hold when he did WOT -- sounded like cut-outs)

And HEATSOAK the blower. We were going to do a cold start, then warm it up, but circumstance be, this is what was decided.

Why? Because road racing, its gonna heat-soak, and that is how Ryan did the dyno runs!

So here it is:



That is 55 RWHP and 80 RWTQ on a baby NA VVT SS1 cam and 10 PSI Boost! We did the runs 3 times and they all came out this way...

The torque increase in incredible -- we were smoking the tires on the dyno rollers -- funny -- until I realize I have to buy tires ;o)

VERY PLEASED with the numbers.

Brett @ Jokerz Performance did an outstanding job. Every step was detailed and now, with just the 90 MM snout port, blower port, and the 2.45 pulley, incredible setup.

Ryan and GPI always treat me awesome and did an outstanding job tuning! Ryan drove this several times and really dialed it in. How can you complain with that gain on blower only change -- wow...

-Don

Thanks! I maxed out this setup... Forged and stroked is next!

Drove it 350 miles back today and the torque really showed up... Just Awesome.

Brett @ Jokerz Performance really set me up well. Beyond pleased with his work. Ryan just nails VVT. A blower specked cam and I'd kill these numbers. We guessed 660 RWHP -- so close -- but the torque, that was a total surprise. My numbers were for a heat-soaked blower too!

No glory run this time ;o) 3 straight pulls, consistent numbers. It's awesome...
