Hello all, I've been browsing the archives and all I can say is 'wow' you americans know your stuff!!!!

I'm based in the UK, I'm about to start on a major project next Saturday, well not me, but the tuning firm is. It will be the first Forced Induction project to involve TVR's AJP-V8 engine in the TVR Cerbera.

Background (standard):
Engine is a 75degree V8, 4475cc, 11:1 cr, factory spec is 420bhp, in reality can vary... The aluminium engine is a de-tuned race engine for the road, wet sump unlike its race brother which is a dry-sump. Billet crank as standard and an block so rigid, it can be used as a stress member, with forged cams. She currently can hit 100mph in around 8 seconds standard. Top speed of 190+ (vibrations make you crap yourself, but I've heard of people taking her well above 200mph)...

Upgrades so far:
I've upgraded the suspension to Nitron mono-tube racing shocks, lightweight 18"/9J alloys with 275 rears and 255 fronts. Magnecor coils and leads. Stainless steel full twin catback custom exhaust install.

The big project about to start next Saturday, will aim for 700 rwhp.

This is the work list:
ProCharger F1R
ProCharger 3 Core intercooler
Crowers Forged low-comp pistons (around 8.5:1)
Steel Rods
ARP conrod bolts
Intake and Exhaust valves
Pistons & Valves Heatshield coated
Head flow work
Custom big-flow headers
72lb injectors
Aeromotive 850bhp Fuel Pump with filter and pressure regulator
Vortex Turbulence Flow exhaust end section
DTA P8Pro ECU and associated sensors

These guys are pro's they've done many hot-rods etc, etc,
although I do trust them, I just want to make sure that whilst the engine
is stripped, if theres anything that can be done now, do it now.

So my question is, What else can I do, to make sure the engine will be as solid as I can make it? and is there anything that I can also include in this stage that will make the end-result more enjoyable?

Stage 2 will be a G5 Zeroshift trannie (clutchless), Denny's Nitrous Driveshafts, and some custom rear-Diff (lightweight but monstor strength)...

Although I got everything pretty much detailed, I'm an amateur compared to most of you on here, so if there is any view or advice you can give or even maybe a recommendation of who to use for custom fabrication of parts, at the moment Crowers is top on the list...

Thanks in advance chaps!

any idea on if the clutch will hold?

i know this might be overkill , but try to get some inconell ( i think that is what they are called) valves, they have great thermal properties that help them resist heat better. the only downside is that the cost alot.

have you thought about your cooling requirements? i guess you won't know untill you get it all done, but helps to have a backup plan.

good luck, sounds like you are building a monster!

Yes pics,...... lots od them.... any pics of the car as it sits now??? besides the sig pic..???

The mouth will be opened and all we'll see is a huge IC...



The G5 Zeroshift trannie in stage 2 will cover the clutch side of things (I think its a 3 peice kit).... but will be spec'd for 2000bhp...

I just need to be make sure the engine is built solid... any more ideas guys?
What ECU do you all use? the car will be running full sequential EFI... the DTA P8PRO is the one I'm going for at this moment... any others to consider? Excluding Motec (I personally feel the price for them is daylight robbery)...

Maybe F.A.S.T or Big Stuff 3, Good luck on the project

I love the Chameleon paint from the factory..... how much doe those run?? 60,000 pounds???

did you look into the AEM standalone computer system?

Nice car.

FAST stuff is easy to use once wired up.

Sure you might not need a bit more injector?

So it would be a triple disc clutch setup? Sounds good.

SXS

72lb injectors should be fine, remember she'll have to be road legal too

Ok, looked into the FAST ecu, and I'm interested.... but I was wandering... will it support this little project idea I had:

I want to permanently install a laptop computer in the car and write some custom software which will show all the sensor readings, but the ECU needs to send this data out via serial, will the FAST ecu do this?
and can I change between pre-configured maps? like an economy mode, performance mode and drag mode?

I am running 83 Siemens low impedance injectors. Of course thru my unlocked T400 my power level is more like 800rwhp.

FAST will allow you to switch programs. You would have to load them.

Does anyone know about what hardening methods I can go for, for the block/crank/heads/cams ?

One firm has told me they can do: SURSULF ferritic nitro-carburising
is this any good? Whats the best hardening process I can get done?

Thanks in advance!

PS. You all share a lot more info than they do in the UK and Japan, why is everyone so secretive about engine modifications etc...???

chuntington101

man that will be one quick Cerbera. very nice set up indeed. if the whole thing goes topgether and works well then i recon some of the Ultima guys would be very intersted!

By the way, where in the UK are you? im near notts in the middlands.

Thanks Chris.

Ok, Inconell Valves it is, will be using SuperTech's services for Forged Inconell Black Nitrated Valves.

Going with either EFI/DTA/Motec... they support cabin switchable maps by the flick of a switch...

The FAST is one hell of a bargain, but it doesnt support a number of functions which I was after.... plus its datalogging is pretty limited...

The Haltech is ok, but no where near the others, the Accell is a good setup, but not enough inputs for what I need....

So I'm stuck between the EFI/DTA and Motec - I think I might just end up going down the Motec route - it has 2-3times more inputs than the competition and supports many maps, but Ouch - the price is a major turnoff!

Chris, I'm based in Bedfordshire.

I'm not a pro by any means of the word. however, i didnt see in your list forged rods or crank. i would think that it would be a good idea to take care of those as well.

only two other problems i see is the weight. TVR = 2400ish lbs (1090ish kilos). front to back weight distribution is supposed to be pretty even on that car, if i'm not mistaken. what will the kit weigh, and how will that affect your handling with the added weight up front?

also... traction hehe, good luck!

Custom Billet Steel Extreme Rods by Crowers is already part of the list.
Crank is an EN40B billet job - and will be getting it Nitrate hardened.

Will be getting the Cams, Crankshaft and heads nitrate hardened to around 4000Hv (if that means anything to anyone???)....

Considering getting the block industrial ion beamed.

Ok, this is the exact work on the engine side:

1. Heads flowed and nitrate hardened (also very low friction)
2. Existing forged Cams - nitrate hardened (also very low friction)
3. Existing EN40B Crankshaft - nitrate hardened (also very low friction)
4. Inconell Valves - nitrate hardened
5. Inconell? Valve Springs (nitrate hardened?)
6. Billet Steel Extreme Rods (Crowers) - nitrate hardened
8. ARP Rod Bolts - nitrate hardened
7. Forged Pistons (Crowers)

The question is, shall I get the 'Block' nitrate hardened and the forged pistons, rings and pins nitrate hardened too?

SXS

For piston crown:

Chrome Molly or Ceramic or Nitrated coating????

(god this is soooo scientific!... any info on this? which coating is the best to go for, for the crowns of the pistons?)

How much does that car weigh stock? For it to do 100 mph in around 8 seconds and only make 420 hp it must be damn light.

SXS

1050kg
Flat-plane crank
Race-spec oil pressure distribution
11:1 SOHC V8 16-valve chain driven de-tuned race engine (bike like revving & TB per intake)
Spaceframe tubular chassis, glass fibre shell, all round double-wishbone setup with coilover dampers...
The race car with this engine weighs in around 700kg and hits 100mph in 6secs.

There are a couple of drag movies with tvr's at http://www.tvrsupercars.com if u want more info on them...

stevieturbo

Thats about 2300lb in US numbers.....

This is a fast car, that is going to become awesome....as long as it can get the power down.
