I was wondering if the spoolup on the tme is suppose to be slower with larger cams installed?

 

then stock? should be faster

 

Depends what turbo you are coming from. Spoolup will be quicker than a 10.5T and about the same as a 9.8T. AFAIK cams wouldn't affect spoolup at all.

 

A TME with the titanium internals should be like stock even with cams. Maybe even a bit better.

 

i think a little faster than stock since the shaft is lighter.

 

Same stock turbo came in Evo 5 and 6; with two sizes in the Evo 6 TME AFAIK...
All with "10.5 hot sides."
Evolution 5
Turbo = TD05HR-16G6-10.5T (GSR)
.........TD05HRA-16G6-10.5T (RS)
Nozzle Area (cm2) = 10.5
Turbine = Inconel (steel alloy), Titanium alloy (RS)
Compressor = Aluminium, 68mm wide

Evolution 6
Turbo = TD05HR-16G6-10.5T (GSR)
.............TD05HRA-16G6-10.5T Titanium (RS & RS2.)
Nozzle Area (cm2) = 10.5
Turbine - GSR = Inconel (steel alloy),
...........RS/RS2=Titanium alloy
Compressor = Aluminium, 68mm wide

Evolution 6 : Tommi Makinen Edition
Turbo = TD05RA-15GK2-10.5T (GSR)
.............TD05HRA-16G6-10.5T (RS/RS2)
Nozzle Area (cm2) = 10.5
Turbine = Titanium alloy for both RS/RS2 & GSR!
Compressor = Aluminium, 65mm (GSR) - 68mm(RS) wide

IMHO Cams, ECUs and exhaust systems are significant factors of quicker spool up and determine when and how much torque is developed.

The Evolution 6 Extreme (1999-2000) from (who else) RalliArt UK, now Extreme Motors also put out -
Power: 260 kW / 350bhp @ 6,500 rpm
Torque: 512 Nm / 377.6 lb.-ft. @ 2,800 rpm too.

The now well known CPP Motor Developments demo/track car started its life as a Ralliart UK EVO VI RS SPRINT, number 6 of 12 built at their HQ in Dudley. The car left their showroom running circa 320bhp...

...out came the factory engine management and in went the Autronic re-mappable ECU with a CPP Stage 1 map. This was to see power rise to near 380hp and over 360Ibft of torque!...

Finally some cam info...
It seems that ECU, cams and exhaust are the key to low-end torque for the 4G63s.
HKS 264........... - INTAKE - 10.8mm lift - EXHAUST - 10.2mm lift
HKS 272........... - INTAKE - 10.8mm lift - EXHAUST - 10.2mm lift
Stock cams....... - INTAKE- 10.8mm lift - EXHAUST - 10.2mm lift

Tomei Procams - INTAKE- 11.5mm lift - EXHAUST - 11.5mm lift
Piper "Ultimate Road" cam set - ideal for stock turbo (autocross) or midrange-oriented big turbo EVO's. 265 degrees of duration with 11.50/10.80 mm (IN/EX) lift.

"Xtreme upgrade - XT350S MR

This latest upgrade for the MR incorporates the XT350 package plus Tomei sports camshafts. Whilst engine BHP is similar to to the standard upgrade, due to our careful selection of performance camshafts, torque increases to a WHOPPING 385 llbs/ft."

High valve-lift with more moderate overall duration seems to produce the most torque at the lowest rpm with stock turbo IMHO.

MY $0.02c

 

nix your 2 cents is worth more

thanks for the info

 

good info.

 

good info, great find

 

HKS 264........... - INTAKE - 10.8mm lift - EXHAUST - 10.2mm lift
HKS 272........... - INTAKE - 10.8mm lift - EXHAUST - 10.2mm lift
Stock cams....... - INTAKE- 10.8mm lift - EXHAUST - 10.2mm lift

Does this mean you can upgrade the Cams without cracking the head? and without changing valve springs etc?

 

i get full boost by 153KPA at 3800 RPM with 272HKS cams

 

Yes it seems that you can use HKS '264's' and '272's' with OEM valve springs.
So head can remain untouched in that case IMO.
The HKS springs may give more top-end rpm, before valve float (at a guess)...

However as a general rule many tuning firms suggest upgrading to ARP con-rod bolts
and ARP head-studs as a precautionary measure. (How much is your engine worth?)

 

There is another post that states stock intake is 10.0 and exhaust is 9.8.

 

??? Are you sure they typed their specs right? What's the thread?
I'll check source and get back to you.

 

Mine seems to spool quicker with the TME and the 280's! love the set-up!
