I will say it if nobody else will - Dom, that looks a very neat install. Try as I might, I cannot see the hair dryers so much in evidence on other conversions. Am intrigued as to what it's spec is for a standard 400 Chimaera, what else would have to be upgraded, and what the total cost would be, fitted.

I do like it but will it be compatable with high lift cams and higher CR ,alot of people may not of fitted wild cams and up the CR if this Turbo kit had come out before now ..

This means reverting back to more of a standard setup to see larger gains .


I thought Super Chargers and ,turbo`s liked flat Cams like the The Piper 270 and low CR`s`

What boost is safe for Setups like mine Stealth Cam etc ..Can`t see it working to its optimum ,surley the cam needs changing with part of the Turbo install.

Good thing about turbo’s these days are you can tune with a lot more compression bigger cams etc, turbo’s will always make good power with a smart ecu if mapped correctly.

You can run 10:5:1 pistons flush and not down the bore "as per old school tuners recommend", use what ever camshaft you want ( within reason), how times have changed for the best since the 80s

That was the choice of the the engine builder but it drives like a pussy cat round town, and a scolded cat if I even think about pressing the loud pedal.
No numbers yet still ironing out niggles, got the engine temps to stay at a tidy 84degs, with my new fan arrangement, just a battery drain to find and good to go

Whats the new setup Richard on the fans I may need something else, dont see you post on here alot these days. Hope your all good

I'm ok just quite busy, now I'm back at work I can have a rest so you may hear more from me
I have a 16" push fan in the nose cone against the intercooler which only just fit with a little body fettling running on a separate relay then one of the original 13" spal fans and an 8" fan on a separate relay on the engine side of the rad with a cowling, It took some working out due to space constraints, i had about 5 mm to spare against the chassis rail but theres absolutely loads of draw through the front grill and no overheating issues now, oh and no need to cut holes in the bonnet for extra vents which was a last resort

Thanks TVR POWER . What dictates the boost ,what is changed to make different boost levels,when are Forged Pistons needed and will the radiator a fans needs upgrading .

Does it get much hotter in the engine bay
will the injectors need upgrading and to what size .and what will the Power be on the recommended boost level with a standard 4l,4.5 and 5l.(will the 5l need a larger Turbo)

Sorry for giving you an headache !

And will the standard clutch hold on.

[Pupp]

Where can I buy one of these burettes that gives a 12:1 CR on a road driven 2 valver?

Do a compression test then divide that by 14.7.
I have a low 7.5:1 cr and 110 across all cylinders

HTH

Don't think that works, as that would give u swept volume less any valve overlap

Yep you said!

Standard 4.0 wouldn't be advised to run above 10 psi because 4.0 clutches wont hold the big torque curves, 4.5s should easily take 15 lbs as they run 5.0 clutches as standard fitment from the factory "unless stated otherwise", kits fitted at Power automatically have larger injectors installed because the std land rover ones run out of injector timing when mapped with MBE system.
.
Our 5ltr factory spec is in build as we speak and won't be moving of our rollers until I see 500 bhp @ the wheels, I'll keep you all posted

Obviously steel crank steel rods and forged pistons are the best option for big numbers, once you've all had a test drive in my 4.5 chim then decide between yourself if you want more Hp.

I thought the TVR 5l engine has the infamous weak crank ! 500hp through that and it will break in two .

What about radiators ,fans and what LB injectors are you useing .

How come TVR power can come on here telling us all about his Turbo conversions etc etc obv trying to tap into the market, but other peoples posts get binned for showing pictures of work they have done

Pistonheads is weird!

What size turbos are you running and what brand are they??

[spitfire4v8]

Other turbo installs are available
