5.0l 500BHP NA Rover V8 take 3

[Transmitter Man]

5.0 with TA Heads, why are so few people using them in the UK?



The camshaft is a roller design It is 596 lift in and ex

258 degrees at 50 duration

Pulls from 3000rpm strong to 7200

A 630 roller cam is available with same duration and picked up 20hp and 15ftlbs across the range

Look like it is 337cid = over 5.5 litre engine..
Spending +2100£ + vat and freight charge to get extra power is not cheap.
And what i have seen only one and hear 2nd dyno test results they have got approx 100hp less than those australian made engines.. Best results what John Eales say it is 460hp with 5.3litre engine.
If you run street, you get lot of more torque on low speed rpm with fully ported rover v8 head´s..
My 5.2l engine give 130Nm (95lb-Ft) more torque on the 3500rpm than this race engine. Street car it is very important..

I hope to get my car run next summer, and see if offset hand ported valve seat will perform better than STD 3angle valve seat.. Also throat is 2.15mm bigger now, but it is offset.. And still running STD home ported heads..

Very impressive Phil butt that is a very big cam.

I thought the cam lobes hit the crank / rods at that kind of lift.

[Transmitter Man]

Alan,

No the cam doesn't hit the crank.

The latest engine has 697 lift with 3.625 stroke revs to 8000rpm with 577hp Tuscan has over 500hp at the rear wheels and y,es we use only rover blocks.

Surely a pain collecting the groceries.

Hi transmitter ,
Ive used ta heads on a 5.0 and yes atttained over 500hp at 5500rpm with a milder solid roller cam than used in your example .
And with rover firing order sounds so much angrier than a ls or sc rover.

[rev-erend]

Hey Phil - any news on the progress of your car ?

[GTRene]

500 NA hp from a rover engine?
sounds good, can they handle such power (reliability)? and is such on a base 5.0 TVR rover engine?
or could such also be done with a 3.5 base engine and then made larger, guess such would be costly...

at what cost would be such package, is that building it up yourself or do they build it up for you.

Impressive to the point of disbelief. That's 95lb.ft/litre from a 2 valve engine.
Be interested to hear what Dave Baker makes of those number

Hi Tarmac - are you based in the UK ?

I take the ending is in a MG V8 .. like a costello conversion.

[TarmacRV8]

Im in Australia rev. Its in an mg rv8.

What is so hard to believe?
5 litre v8. Pushrods and 2 valves are in LS chevs, v8 supercars, nascars etc

Power is more than a sum of parts, same parts had 380hp old engine , 530hp new engine.
150 gained by experience and $$, 1% ers add up

Yes I did use a wise old championship winning engine builder (his first rover build) reworked the TA heads, jed crossover manifold and at a cost equal to their retail price and built a new equal length tri y header and exhaust to boot.
A bigger duration roller cam than the 245 in it and wed be closer to 600hp.

Hi Alan,

My car is in dry secure storage in bucks.

I'm flying back to the UK soon and plan on visiting Topcats a local TVR shop and discuss continuing work on my car. Complete the chassis build, mount the body and install the EPS. That will be affordable I hope until I save up further funds.

You're out that way. Any other shops worth looking at?

I'd also like to hear more from our 500+ bhp friends in this thread.

Be nice to see a graph.

[Boosted LS1]

For RV8 work I'd go to V8D and I'm a builder. fk the rest, they know peanuts lol.

TarmacRV8 can you email me through Pistonheads please, your account is not set to receive emails.
Thanks

What transmission and clutch setup do you guys run when pushing 500bhp?

Running a 3.5lt RV8 Turbo, pushing 350hp 375tq to the wheels. Stock LT77 trans with Centerforce 10in Clutch.

Thinking of building a 5.2lt with same turbo setup, but worried about the trans and clutch.

Thanks for the recommendation Jes,

I'll have to get them to come look at my rolling chassis for some ballpark work costs as I cannot afford to overstep my funds for the next step in completing the build.

Thanks.

A 2 valve, pushrod, parallel valves engine at that. Not sure I buy it, either.

I had a 5.0 TT with a rebuilt LT77 and it was fine. I never loaded it up to much in 1st or 2nd and if I did it would smoke the tyres. Rear diff was 2.84 with lsd. I loved the whole package. I couldn't find a decent single plate clutch so had to buy a twin plate mcleod which I think may have been a chevy item. It was mounted with the bolts half way into the ring gear. I also had to put a couple of slots into the bell housing to get pressure plate clearance. The pressure plate had 3 levers instead of a dozen fingers. It was a really nice clutch with a light pedal feel.

A friend did a conversion with a 3.08 diff and he wrecked 2 gearboxes but he had no mechanical empathy.
