comp cam for ve ssv

[priddy7]

I've just orded a comp cam for my ssv (114 overlap) and wanting to know if anyone has done this mod to there car, and if so what power is it making????:outlaw:

[WAVESS]

Whats the duration and lift Priddy?

[priddy7]

yep it's has 224/230@114
581/592 lift
Also have full 3"di fillipo system plus a cold air intake.
have not put cam in yet but intrested to see what it should make.??????

[vyssbeast]

You sure that'll fit?? I heard the biggest an L98 will take was 224/228

I don't see why you couldnt chuck a 232/234 or bigger into an L98, its just that no one has done it yet (to my knowledge anyway)

carlfst6l (I think thats his name) has a custom sonny cam in a VE r8 and it made 300 at the rears and is evidently a great drive.

I presume the L98 is like the ls1 in that it loves a lot of lift, so that cam should be good. Personally I'd go lower on the lsa, however if you want a smoother idle 112/114 is preferable

it doesnt have the clearance for the bigger cams unless you shim the pistons, etc which is big $$$$$

thats what i was told anyway

That is an LS2 ... no1 said anything bout the size that can go in an LS2

But as excssv said, apparently it is phsyically not possible

[EXCESSV]

When speaking to Dan (Delco) @ Chipmaster he said the following why its not possible for anything bigger than a 224/228 as i was looking into doing some 23X/23X

Piston to valve clearance , its not just about the lft but the valve event timing

point taken mate, as they say you learn something new everyday! In any event, carls cam is a baby, only a high 21x, but still made the numbers. I'd be interested to see how a cam with similar specs to mine would go in an L98 (assuming it would fit)

It may be physically possible to go bigger but you would want to have a very close look at the valve events and measure the piston to valve clearances very closely , even with the LS1 just because you have piston to valve clearnace doesnt mean they wont kiss the pistons at times , have seen lots of not so big combo's with bent valves/damaged engines.

Personally I would not be slotting any cam into a L98 without doing a lot of measuring and checking physically - as you should do anyway

LS2 is a different design and has valve reliefs

I'll keep an eye out!

[vyssbeast]

Im also interested!!

But you do make a good point vt350, if carls cam is so small yet made those numbers, makes me wonder why people even bother with the bigger cams.

[priddy7]

so what you guy are saying ,that a 224/230@114 is a bit of a tite fit for a ssv 6.0 lt

That was my thought indeed, although interesting to see what numbers (and times) one would get with a bigger cam. Have to wait and see what mark12 is up to

[BOSSONNOS]

mmm tight fit

Trust me Priddy it'll fit and make good numbers and won't be a dog to drive :burnout:

Oh and your Rip Shift is here too

[priddy7]

Cool I'll be over too have a look about 5 . Yep it sounds like it
going to go alright. GO AND DO SOME WORK:rofl::

That we will :)....which is why the ET MPH slip.....as is well known, there are plenty of smaller and much slower cam only LS1's that proudly proclaim the same ...or bigger dyno numbers :confused: than our current and ex crop of QLD full weight big cam 11.00 & 122 + mph cars and ute.

markone2
what size cam is installed in the L98 that your testing?

You won't believe me....but I'll tell you anyways..* I don'T know :confused:*......having left all the finer points of the L98 build to the good folk at Power Torque......but :)....one would be wise indeed to read 240 plus into the equation imho

[Momo]

L76 & L98 are the same engine. The biggest camshaft you can put in without having to modify anything is a 238/240.

That has custom pistons with valve reliefs I would say

[Momo]

With standard pistons and no valve reliefs or any mods at all you can put upto a 238/240 comp cam and have it run to 7000 rpm all day long with no problems whatsoever. Also provided you fit correct valve springs too.

Hey Priddy, have you seen the golf thread yet, that's right up your alley and it'll get you post count up :)

is that the cam u have?

[BOSSONNOS]

I know this isn't related to what Priddy's intial post is about but here is photo of the first set of extractors we fitted on his SSV after 4 power runs.

The cats still looked like this after about 3 mins

[Momo]

Yes that is the cam I have , hence the reason I can tell you what is the largest that can be put in the 6.0, as I wanted the biggest cam I could fit in there and Power Torque measured it all up and that is the highest you can go with no mods and safe piston to valve clearance.

Like I said it comes down to valve events and lift , I prefer smaller duration high lift cams , but if large duration mod lift cams are your thing then cool :)

Mark would have done his homework and measured it all up.

But by you giving internet asurances about how much lift and duration you can go on a L98 are you going to warrant your advice ?

[markone2]

I would say your 100% correct Mr Delco :)...plus a bit of balancing an a bit of this ..an a bit of that...and yep...240 plus I promise you.......but alass....I can't give too much away before the ute runs....as this is PT's baby....so to speak.

[Momo]

The cam has a high duration and a high lift its over 600+ lift on intake and exhaust.

Delco - I am simply just trying to answer the persons questions with actually having done what he is asking. I am not out to warrant anything. Just talking from real experience and proven measurements that have been taken by a professional engine builder. Everyone knows the L76 and L98 are one in the same therefore it applies to both engines.

[EXCESSV]

think when the time comes i will stick with a 224/228 as i want nice low down power rather than the cam starting to kick in high in the rev range.
not after a dyno queen...after something thats gonna rock and roll from the word go and be able to be driven daily comfortably.

plus leaves options open for nice valley mount later on

[priddy7]

has anyone done a 230+/230+ cams in the ve's yet . I know GM has but they are being tight lipped on the specs . If so can you put your specs up and how they perform.

Cam in the L98 Ute is comp 244x248.......very different drive to my Head /Cammed 5.7 SV8, with the power delivery from the 6L coming on strongly from 3500rpm.

After driving both the 5.7 and 6L back to back the big cam only feels outright lazy when compared to the neck snapping rush as experienced in the 5.7......However, track times indicate both vehicles currently evenly matched in outright speed stakes, with my money on the ute outgunning the SV8's 10.76... now that the engines got a couple of Ks up and the tune can be touched up accordingly :)

for that size surely u fly cut the pistons and some head work? :confused:

read post 29.

[EXCESSV]

read post 29.thanks dave :doh:

[ringram]

p2v clearance is usually down to the intake valve clearnance on valve opening as it opens normally (dependant on valve events) before TDC when the piston is still rising. With the larger 2.16 intake valves on the L98 heads thats whats going to chew piston.
The 224/230 is 230 on exhaust which is only 1.6" anyway and is closing as the piston rises so should be ok.
Of course you must measure and the rule of thumb from memory is 0.100" min clearance from memory (best you check that too though!)

Thanks for the post .
With such a large cam what is it like around town, is it a bit rough! And is it a 112 or 114 etc .
Was there any problems fitting it .
So what rwkw is the ute putting out now or are you still doing a tune for it ?

Rough :confused:....Confess I was pleasantly surprised, those extra cubes ,no matter how small they may be hide a multitude of sins and have left more than one forum member here shaking there noodle in amazement at just how docile this engine is given the cam size
Ute pulled 324rwkw on maiden dyno pull ..328rwkw run number two with another 328rwkw on third run with zero ks up on engine. Quarter mile came in at 10.92 @ 125mph first pass on run-in tune ...after which I was kindly asked to vacate the premises..post haste :bawl:

For LSA / Lift etc you'll need to ask the good folk at Power Torque :)
You WILL need valve relief, no way around it unfortuantly .
