Yeah, something along those lines. Will swap out to an LSX block if I want to push it any further.

Ignore the haters and go for it I say. It's a massive commitment financially which I for one wouldn't bother with again as the money can buy factory cars which will be faster in every way, although no where near as individual which is normally the attraction of such a build.
Ignore Rich as well, he hates boost.
Ironically, he is the most supportive and I am working with him on this biggrin

But yeah, it is the individuality of this build. One of 3 ble GTS in the country, and the only one with four figures. Unique!!! biggrin

As we all know, valve float is a terrible thing, so what are peoples favourite springs?

Will probably use a BTR Comp Cam Stg3 for now till I work out what my final cam spec will be for an idea of what lift and rate they need to support. I see BTR also do a spring kit, anyone used these? I'm guessing Gurmeet is the man to speak to.

Yes, totally sure. This was always the plan and I bought the car to keep anyway. Money has to be spent on something after all else there is no point earning it. I have everything I need, now to get the one thing I want that doesn't have four legs and wags it tail smile

Lingenfelter got to 927bhp, just another 75 to find and I have ideas about that. http://www.lingenfelter.com/page/lingenfelter-927-... Granted they did use a KB 3.6l, so will maybe up the screw size. It is staying PD though.

Seriously? Can you just fk off with your negativity please. This is my build thread, my targets, my money, my car to do with what I please. If I don't hit my targets, then what a shame, it is only a target after all. the point of linking to that Camaro was to show that the block is capable of similar power levels like you all say it can't, as per the damn thread title. I personally believe it can, and my research is showing that it is possible. Now if you don't have anything constructive to say or have a specific answer, get the fk out of my thread.

Waiting for parts from across the pond sucks bigtime. Just waiting on pricing for the BTR stage 3 cam kit which I should get back today. While the front is off for the cam, I may as well up the boost a bit, so will up the pulley size smile Thinking of this but unsure how much to overdrive it just yet, need to run the calcs http://www.lingenfelter.com/product/L220050709.htm...

Also forgot to mention in the OP that the rev limiter has also been raised, so the retune and air filter should give me over 500 to the ground.

Need a nice dry day to get out and data log to see how she is doing and maybe drop in to se Charlie if he has a dyno day going at any point.

In Wormus defence it does say using 109 race fuel so it's not really a good example. Of course it's possible to produce a 1000hp whipple build. But it would be absolutely horrible to drive and certainly not a daily driver. The advice you have been given is that you'd ruin a brilliant car doing it. Which I believe is very good advice.
If you want to build it then go for it and I wish you luck

Sorry, but he can fk off with his attitude.

The fuel is good for 30-50 bhp tops. I thank you all for your advice, point repeatedly taken. Now please can everyone stop mentioning money, turbos and any other irrelevance to this build.

As I stated earlier I was pointing out the merits of the lsa block, and am working on some airflow and charge cooling changes that will help reach my goals. As we know cold air is good, hot air is bad. Improve the airflow over the components lingenfelter used and this will help keep the air temps down.

I am going into this eyes wide open, trust me on this. If at any point I think more power will be bad then I will stop. But not before.

Seems aptwink

Meant in jest, but if you are going to do this build in the public eye then expect some flak and not just sycophantic admiration.
You too. Jog on.

I was actually basing that statement on an independent dyno test of that specific race fuel on a 600bhp machine giving a 25bhp gain over pump fuel and associated spark advance. So yeah, I know nothing.

Cheers Max, I am just starting out on this, I hope I have shown that the block was capable of taking the power, next up is calculating airflow requirements as you so rightly point out. I have found heads that flow a higher rate than the ported LSA heads, which is always a good start, will double check they can flow enough through the correct calcs.

Jez, your edit makes your post a bit better, but rather than just saying I am wrong, explain why I am wrong. This is a learning exercise for me after all. I respect your knowledge and value your friendship and would like to learn the technical stuff from you but I believe no-one in this country has tried what I am trying so give me a break and help.


@everyone
STOP MENTIONING MONEY. I DON'T CARE ABOUT MONEY

Sorry mate you are wrong on the fuel issue and this is not even race fuel...
You are comparing apples with oranges there mate, E85 is totally different to 109RON race fuel.

Lingenfelter sell a crate 900bhp LSA based engine on pump gas. http://www.lingenfelter.com/product/L130286509.htm...

Might need the 4l whipple, but this build is on. Can we get a "HELLYEAH!"

Yes, but he has bought an air filter remember.
So you would use a stock airbox would you? wker.
