violetpop Silver Donating Members 436 Member For: 4y 4m 16d Posted 29/12/20 09:45 AM Author Share Posted 29/12/20 09:45 AM Back at it again today! Big thanks to@joncitizen hooking me up with the sump arches at short notice! Big days got lots done. First up I started with the sump getting it all sealed up and tightened down.The moved on to getting the engine in the car and went about bolting everything up. The engine is huge! I started with the inlet manifold first, then exhaust side, rear main seal and trans and finally the cooling system. Cars running smooth, oil pressure primed up no drama. Let it idle for a bit and all looking good. No left over bolts and no check engine light. Winning! 4 Link to comment Share on other sites More sharing options...

violetpop Silver Donating Members 436 Member For: 4y 4m 16d Posted 29/12/20 11:46 AM Author Share Posted 29/12/20 11:46 AM Yeah mate, I'll sleep well tonight knowing I don't need to chase some random issue. Just a few things left, tail shaft front bar and general tidy up and check over. Still need to decide on who will do the next tune and hopefully back on the road asap drive the bloody thing Link to comment Share on other sites More sharing options...
violetpop Silver Donating Members 436 Member For: 4y 4m 16d Posted 31/12/20 04:39 AM Author Share Posted 31/12/20 04:39 AM Little bit left and completed today including tail shaft, front bumper and bonnet. Dumped the oil and filter after running the car for a little bit and refilled with some fresh Penrite. Also noticed the plastic cap that sits over the butterfly rod had popped out over the weekend of my high boost bonanza so I've rigged up this plug which I trimmed down to be a push fit with a bit of silicone for good measure. See how it holds up in the future but ive got a 4 pack to get it right.Thinking if now is the time before retune to add a dump and cat combo or just stick with my bolt in cat. Just want the car to make easier power with lower boost. Any suggestions? I'm looking at the advance headers 3.5inch dump and cat combo. Another option is pick up a cheap dump and get an exhaust shop to cut and shut my venom bolt up cat to work together but I suspect wasting my time going to an exhaust shop for them to piss in my pocket, charge me $600? labour is really not worth it.

At this stage I'd just do the cat cos I doubt the dump will be a restriction just yet. But if you're going further with it down the track then sure, chuck the dump in now, you may as well. Either either, there's my 2c Link to comment Share on other sites More sharing options...
violetpop Silver Donating Members 436 Member For: 4y 4m 16d Posted 31/12/20 05:07 AM Author Share Posted 31/12/20 05:07 AM I thought about just leaving my venom bolt in cat but when I had the car apart inspecting the stock dump, it just doesn't look like its up to the job but maybe it is. Is the dump something to look at from 400+rwkw? Link to comment Share on other sites More sharing options...

You can do 400+ with a stock dump, it depends what you want to do. 1 Link to comment Share on other sites More sharing options...

With the stock dump into a 3.5 cat I had 495rwhp at 18psi but it felt restricted to me up in the rev range. You are using e85 in the LPG motor? You might find yourself well over 400rwkw 1 Link to comment Share on other sites More sharing options...
violetpop Silver Donating Members 436 Member For: 4y 4m 16d Posted 31/12/20 06:26 AM Author Share Posted 31/12/20 06:26 AM Yeah next tune will be full time e85. I cant see a dump and cat being a backwards step in any way so perhaps I will pull the trigger. 1 Link to comment Share on other sites More sharing options...
adams355 Member 529 Member For: 6y 11m 23d Gender: Male Location: Brisbane Posted 31/12/20 06:44 AM Share Posted 31/12/20 06:44 AM (edited) Well you might want to ask some folks on here the old 3.5" vs 4" dump. I use 3.5 to 3.5 cat because its my daily and im not on boost or my max boost all the time. My tuner will only use 4" but he tunes 1000hp cars all the time so... I think I remember some saying on here that 3.5 was good enough for a fair bit. Edited 31/12/20 06:46 AM by adams355 Link to comment Share on other sites More sharing options...
