Two quick observations...

(1) You appear to have a problem, and it isn't the cams. It could be a substantial pressure leak and/or a tuning issue. That turbo cannot possibly be that laggy.

(2) Your +1/+2 (in/ex)cam timing adjustment widens the LSA from 110 to 112 deg, and that isn't going to help. +1/-1 will help, but it won't fix the root cause of the issue.

 

I have done a pressure test and it holds near 28psi with no leaks, that's with the evo 9 bov still on as well

fitted a new forge actuator with a 20psi spring and adjusted preload correctly.

Already had the turbo sent back and re checked but they found nothing wrong infact they blamed the cams so I invested in adjustable pulleys

 

What about the tuning?

 

That has to be it, the only thing left I guess.

I am still running the same map which I had done on stock cams, Its a evo 6 ecu, with 3 port and denso 660 injectors

All I've done to the map since fitting the cams is remove some timing to shift knock and got it to run a tad richer top end still spools 12.5ish but drops into 11.5 at top rev's

I've set the base ignition timing to 5bdtc

This is before cams and turbo






Still hitting the same load settings on logger

 

I've booked the car in for mapping on the 23rd, If they sort the lag issues via mapping what cam settings would you advise with the kelfords

 

Normally, I advise to run them straight up. If you already have the cam gears, try 0/-1 (In/Ex).

 

I take it kelford's are normally spot on then. Thanks for the pointers

 

hey ted great advise

for my fp black 2.0 on s2 what would you recomend?

for my fp black on 2.3 on kel 276/272 high lift what would work best?

love the advise

 

FP black 2.0 on GSC S2 = 0/0

FP Black on 2.3 on Kelford TX276HL = -2/-1

 

Looking for some can gear settings for a S1 cam on a 2.3 with a EFR 7163. I need all the bottom end and mid range power I can get as this is a autocross car.
Any help would be great

 

+1/-2

This reduces the LSA from a leisurely 110 to more aggressive 107, resulting in a choppier idle, but quicker spool and more midrange torque.

 

Ted, currently building a
-2.3L 4g63 10:1
-s3 and will be using a hta82 with tial vband

what would you recommend for street use
and do these cams need to be dialed to true 0?

 

You should not need to move the exhaust cam.

The S3s will give slightly quicker spool with the intake at 0, although the short rod/stroke ratio of the 2.3 should yield a little more power upstairs with the intake at -1 or -2. The reason for this is the short R/S ratio means the piston moves faster around TDC, which has the effect of behaving as if the intake cam is slightly advanced. Because of this, a 2.3 needs the intake cam slightly retarded to give the same characteristics as it would with the shorter stroke 2.0. If you have a IX and are using MIVEC, you would simply reduce the advance a bit after the turbo has spooled.

 

Should swap the S3's out for R2's.

 

What's ur reasoning ?
