I am thinking of getting the TSP 224/224/.581 cam with a 116 LSA. What are the disadvantages of this compared to a 114 or 112 LSA? I'm looking for a smooth idle.

Why take away from DCR/lowend? a 224 on 112 will have a smooth/MILD lope
u want a smooth idle? Get some new motor mounts.

ya the 116lsa will have a real easy idle not a rough one, your powerband i believe will come in at a later rpm because of the high lsa.

Unless it has a lot of advance ground in, do you know what the advance is for this cam?

YankeeVert.

No. They don't list it on their site.

Anyone know at what RPM it will peak at?

PREDATOR-Z

On a116+0 it will peak in the 6300 neighbourhood and rev till past 6800
Advance it 116=2 and then midrange trq comes back into play while still carrying past 6600.

I used to run a 224/220 116+0 and it was very smooth (nervous rapid chopchop), but good number capability and netted 11.3 H/C with 11.0:1 SCR

The 224/224 will act the same but be a little more exhaust biased.

Thanks for the input. I have a 02 Corvette with a SS3600 stall and 3.73 rear. Do you think this cam will be a good match for my setup?I'm looking for a smooth idle and good drivability in traffic.Most of my driving is below 50mph.

PREDATOR-Z

Yeah on a 116+2, be prepared to rev higher like at least to 6600.

YankeeVert.

Any problems on a 116+4? I would like to shift my A4 in the 6300/6400 range.

Thanks

PREDATOR-Z

I would prefer a 115+1
see it has to do with EVO
116+4 has EVO of 52 pushing trq band higher up (less in midrange)
while the 115+1 has an EVO of 48 which will be more pronounced in midrange
with a -6 overlap it is still in the good idle not to choppy spectrum.

YankeeVert.

Thanks

Do you like this more than the 116+2 ?

PREDATOR-Z

Yes..
just remember that cams need to be degreed to make sure it is installed on that ICL.
And before you ask, dot to dot doesn't necessarily mean it is on that ICL even if in the grind. An adjustable t-chain is necessary.

man you need alot to learn about cams. what do motor mounts have to do with an idle behavior? sorry thats wrong info. A 112LSA will rock the car period.

Anyway, yankeevert...yes you will have a silk smooth idle with the 116LSA. You basically lose a little low end grunt. Most of your powerband will be up high.

eamador11

Trust me, with todays tuning capability, you can still get away with 114LSA. And this way you wont lose as much tq down low like with a 116. I know this because i did that exact thing on the first cam upgrade on my vette. then i swapped to a 224/228@114. it has lope but the car still idles smooth inside.

I don't mean to change subjects here, but could he install adjustable cam bushings to change the ICL? I've seen them before, but don't know how they're favored in the LS1 world.

good morning, guys,

hey, predator, you got pm.

YankeeVert.

Thanks for the input.I can live with a little lope. My main concern is that I do most of my driving in traffic or on city streets.I have the TC locked up at 35mph and that gives me about 1500 RPM as I cruze down these streets.I don't want the car "bucking/surging" under these conditions.Can you give me any input on this.

Thanks

Are you street/strip or street only? What exhaust are you running and what emissions requirements? Stock heads or ported?

YankeeVert.

Steet/strip. More street,I go to the strip about 4 times/year.I have Kooks headers(1.75) highflow cats and Z06 Ti exhaust.
