Holden V8 5.0L Upgrade Options – Pros & Cons

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

For the power SSEn8r is after and time money and effort he wants as he has to pay mechanics to do the swap I think cavas engine combo is perfect

It will be a 2 day at mechanic turn around, minimal labour cost and good bang for dollar, afterwards can either keep your original motor or sell it to get some of the money back

Like cava says, throw in the pump he has listed and it’s all a direct bolt In and away you go, then if you throw in some 3.9 or 4:11 you got a high 11 or low 12 second car for under $10 grand mods

That will be hard to beat for them dollars

Thanks Gary, I think I will put a small thread together when I have it up and running in around 4 weeks (hopefully)

And couldn’t agree more with VS Manta 218.  At least you’ll know you’re getting a quality built motor from Cav 454. Thats the beauty or curse of the modified scene.  You spend big dollars to get it up to where you want it, then you have to let it go at a fraction of what it owes you.   You’ll never build a replica engine for the same price even if you are capable of doing all the work yourself.

If I was starting out SSEn8r, I would seriously consider that set up.  It is a good platform for improvement if you wanted to take it to the next level with a wipple etc. (girdle)

On paper, an 11 second car isn’t that quick by todays standards with everything being boosted.  But, it’s not until you run an 11 for the  first time that you realise how fu*king fast it actually is.  Especially considering the latest Ford offering (Herrod built I think..) is putting out 500kw and has only achieved a 13 second pass.  (Must be issues with that surely??)

Anyway SSEn8r, build what you want.  It’s an exciting time being at the stage that you are.  It absolutely consumes you.  And that old cliche is true, you will never be happy with your power level.  You’ll always be searching for more…  Enjoy your build mate.

Everyone wants to run a 10 cause the guy next door is running 9’s. Then they soon realize what it costs to run an 11 lol

 

mine will bake top gear to put it in a more streetable perspective lol.

Yep whatever power you make give it a couple of weeks and you will want more….

i’d be at least keeping the block in the shed,if its an original numbered car.

y/t 2.3 whipple sounds good,if you can fit it you’ll stay under 15k with exhaust upgrade,kits 10 with cooler i think.

100% agree with that, mine is under the bench in the shed, really they arent worth that much to sell, so you may as well keep it so you can go back to matching numbers if you ever want.

Option 2: 10 psi V1- V2 Vortech charger with water/methanol injection should see 260-280 RWKW and the standard engine can take it.

Its cheap power.. buy if you want to get serious then built a 355 that is ready for boost and get an intercooler.

But if your on a budget and like your 5.0 304 V8 then V2 or V1 T trim with a crane 284 cam, water injection kit and tune should keep you happy until you can afford a stroker.

I wouldn’t recommend that cam for a supercharged holden 5L engine at all, if it’s already fitted in engine then yeah could keep it but it’s not perfect at all

I would suggest 114 LSA, I would go 115LSA on a Yella terra top mount blower

unless you have a off it’s tits solid cammed 355-383 with power range from 3000-7000rpm and 13psi + boost as much head work as possible built for mid to top end power when you can start to go for 112 LSA if you choose to and even then it still very controversial and most will still advice 114 LSA even at this level

And what ever duration you get you want the exhaust to be some where from 4-10 degrees more on the exhaust side

Supercharged holden 5.0L are mostly about getting the exhaust gasses out and that’s why you need this extra exhaust duration

So would go
220-224 for entry stock motor nice to drive smooth full rpm range power
222-228
224-230
224-234 with a bit of work to motor

Personally I would stick with 6-8 degrees extra on exhaust

If you go down this path call crane or come racing or a cam specialist to choose a grind and don’t get a N/A designed cam that is almost right

Crane 284 is a VERY good off the shelf boosted cam. Tried and tested.

so if you your self cava had a stock or fearly stock 5L and where putting a cam and blower on it would you put a crane 284 in it ?

Or would you choose something like a 220-226 114 LSA 0.480 ? Or around that region

And it’s a vortech blower we are talking about here not a turbo engine, because a turbo acts like a low comp N/A engine till it spools up bring the intake and exhaust durations duration a little closer together makes sence and can also go a little less on the LSA as turbos don’t push intake charges out the exhaust as Easley as supercharger engines do

but this is a vortech blower engine we are talking about

Claydo dropped to a 284 with his v7 355 that was running 9’s after he put it in his Vn and made it streetable. I’ve been in that and it hammers 440 odd RWHP. That

Another mates got a 284 in his 200+km stock vn with a precision 6766 hanging off the side. That’ went  300rwkw at 6000. Its a great cam. Tried and tested.

[vs manta 218Participant Vs hsv manta View build HERE Member since: March 2, 2015 Posts: 796]

So who has used a 286 compared to a cam similar to like I listed to compare the results ??

Just because people have used it doesn’t make it great for the job
