You are really bad at the internet. You asked this exact question a few pages back. Innovate SCG-1, it does have boost cut. It just doesn't have boost by gear or RPM or some other strategy.
The factory ECM has a horrific time managing transitional fueling between vacuum, power enrichment and...
The family and I will be coming from Drumheller to Medicine Hat for 15 Aug for Day 1 of Miles of Mayhem, and heading home to SK to be at SIR for Day 2.
I hope to see some of you out there. If anyone participating needs anything on Day 2+ my door is open.
I know right? Here's a blow up of the... err... blow up.
It peaked at 18.5psi at 4910rpm and 0.738 EQ - that might be asking a lot of any engine. IAT was 151*F, it was coming off a minor bit of KR, and had less than 6* of timing,
Yeah, I am with you. However, there are lots of direct bolt on forced induction kits for LS and LT engines where no internal modifications are required and lots of longevity to support their use. Again, my educated guess for my failure was extreme cylinder pressure below MBT. A programmed...
Here are the factory ranges for a stock, new, LR4 4.8L:
Top
0.23-0.44 mm (0.0091-0.0173 in)
Second
0.44-0.70 mm (0.0173-0.0276 in)
Oil
0.18-0.75 mm (0.0071-0.0295 in)
That's a pretty broad range, definitely tight toward acceptable with mileage/wear in a JY turd.
For comparison here...
The Procharged stock-ring gapped LS2 in my TBSS would like to have a word about that.
Not sure I want to drop another hundo on a cheap gapping tool, ring pliers, and a ring compressor.
It, the significance of it, will make more sense to her in 10-15 years when she starts intuitively applying these lessons to other seemly unrelated things in life.
Supply chain issues and budget limitations dictated what I got, and when. Could have got some LS9s through Amazon from BTR for the...
A balls-out port job on 241s can net 300+cfm. I am just hoping for something in the 260+ range.
The 706s are Castech. They weren't cracked before installation... and I am hoping they will be salvageable once I get into the 5.3. I'd like to keep them on hand. A little bit of my time, mostly to...
It was on the table... but, it was a trade off of flow vs. compression. I'd rather have the compression. For reference, the stock 706 heads have 61cc chambers and the 241s have 66cc chambers. This drops the static compression ratio from ~9.5:1 to ~9.0:1 - and I don't want an off-boost dog.
I...
So we finally dipped into the 4.Grape. First step toward Full Send: Break Seal.
Next step, pull off the crap standing in the way of the cylinder heads... and then the heads themselves.
Fortunately when I last saw these heads, about 2.5 years ago, I was at the cartridge roll stage. So out...
Per the archives of the internetz:
The car was factory optioned with PS, PW, PB, PT, T-tops, A/C, delay wipers, and cruise control. It is 1 of 200 cars that was able to be optioned with black paint and the black-out package in late-1986 (1987 MY), and lighter than a Grand National of the same...
Got my annual performance review in the mail. My fourth MOI. Performance: Mastered. Potential: Outstanding. Promotion: Immediate.
That's as good as it gets. 3 is the requirement for that next level, plus a stint at Clown (Staff) College. All done.
Yet, here I am again a bridesmaid.
7 years a...
I've made my decision.
Reasons? My time is in short supply these days, I despise doing work twice, and frankly this is what I want in the car. So... it's time to finish it. It may take a bit longer than originally estimated - head porting is time consuming. But, the result will be...
Amazing the difference that a 60' time makes, eh?
But, yes - you are still leaving a lot of time on the table by short-shifting it below 7000rpms. Understood that making clean runs makes that near impossible get consistency/feel. And yes, numerically your gear change has opened up a world of...
