Opinions About TSP 231/236 Cam - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

CamaroFan22 · 11-07-2015, 07:34 PM

Ok, so I'm planning to swap in a cam in my 2011 SS LS3. I was looking at a Texas Speed cam package that includes a variety of options for springs, push rods, timing components and obviously the cam. I really like their 231/236 cam with a 112 LSA after I've watched a few videos of it and I want to know what anybody else has to say about it. Does it buck real bad? What's the average HP gain vs other cams? Will I have to change anything else in the motor? Etc. And maybe some other suggestions... Thanks.

Gear ratio will get you some better answers

The tune is the answer of your question about buck. Get the best tune you can and you will get drive ability cose as stock.

Bud I had one with more aggressive lift than that from TSP, was a awesome rocking cam, and unfortunately sooner rather than later in 10k I had a bad over rev from a missed shift and yada yada four months later one spring broke, then the other within ten miles. The .675 springs I had were hurt from the over rev obviously as were some pushrods actually very mildly bent. The cam you selected is just a .650 spring cam though I think and those springs are even more forgiving. I cannot blame my problem I had on the cam or springs, and I sold my used cam broken in properly by me with Driven br30 with ten K on it looking brand new and recovered some cost..lol, ( Bought a new engine). With the new cams milder lift I have and wider 114+4 LSA I still have about the same amount of cam surge/Bucking as the last cam, I still need to go to about 1500 rpms usually and baby driving slow so hey..... the tight LSA surge thing is second nature to get used too......

My .639/.623 cam netted me with its 235/239 LSA and 112 LSA a good 491 hp and 448 torque on a Mustang dyno with just headers/HFC and CAI through my dual mode exhaust. It is a good cam and I would have used it again except I wanted everything on hand just incase before the build and decided to get a cam motion core with their stage three being a milder lift .650 spring being more forgiving.

Anyway I noticed TSP changed the intake lobe to be .629 now not .639 maybe to help as the higher the spring pressures go the more likely the spring to break is kind of what I have learned. And of course the higher maintenance they are and should be checked every 25k or replaced the more aggressive the cams go.... As its not your grandpas Buick......

You would pay more and change out the timing chain for the C5r, and go LS2 dampener and better Melling high volume pump and be money ahead for ever having any problem with them. Of course you will need the balancer bolt and the three sprocket cam gear. And a gasket set for the front of the engine. With their base circle I came out at 7.425 springs for the cam I had but I know it could be different for you, I have 7.4 on the cam I have now as the base circle is a little larger from another maker with less lift. I used to think I had 7.375 on the car with the last cam but that was just the babblings of a busy Tuner before he ever measured....

For insurance I eventually got a Fluidampr to help dampen the harmful vibrations from the engines being cammed, and though the TSP one looked cheap and so did my tuner so ....I spent more for better. I know my TSP cam was and is still more powerful than the vaunted Nightfury and I am sure the specs for yours are too as its Specs have always like been stupidly secretively held specs by the owners of the cams....lol But I have heard them on here a few times over the years. SO expect good results, and for god sake watch out for Jerks on the road the worlds full of them pulling right in front of you doing 80...... so close you can see the hair in their nose......

I've got friends with both cams 231/236 and 235/239 form TSP. They both make great power, more than the NF. I have the 235/239 drivability is very good. I agree with the post above make sure you get a good tune and all the extra stuff.
I've added heads since, but made 497 on Mustang Dyno also

Jason 98 TA · 11-12-2015, 05:54 PM

We actually did a update to the lobes as we switched to the new Callies camshaft cores. It's just hard to beat Callies quality! Between the two lifts the overall lobe designs are both very good at making big power!

2010reddevil · 11-12-2015, 06:09 PM

How would you compare to Cammotion cores?

Jason 98 TA · 11-16-2015, 10:20 AM

We use callies cores because they are top of the line. Absolutely ask anyone in the country & they'll tell you they love Callies products. With these camshafts you get a cnc cut camshaft on either 5150 or 8620 material! The key is finding a supplier that guarantees to be very close to requested specs, guarantee against grinder burning, and use a CNC Camshaft grinder.

There's been so many camshaft failures on these boards that we thought the best way to insure that doesn't happen is use absolutely the best cores available.

Bucking isn't an issue with a manual. It's really easy to drive and make it not buck. I got used to it in a couple hours. I'm also running stock LS3 gears, 3.91+ hearing will make the bucking even less.

A good tune makes a difference, did you have a tuner lined up already? Ask them about cam choice and if they have tuned a similar set up.

Homeless Man · 11-16-2015, 02:27 PM

Will your cammed cars last 100K miles or most likely not?

Jason 98 TA · 11-17-2015, 02:45 PM

Any valve spring you select for a aftermarket camshaft will need to be changed in way under 100k miles. But from a camshaft standpoint I fully expect a nice Callies camshaft core in 5150 or 8620 to make it 100k miles.

260racin · 11-18-2015, 06:24 PM

I've had this cam for 2 years now with no issues but I've installed every supporting mod nessecary to insure no problems. Melling high volume pump springs ti lifters c5 chain ls2 tensioner trunnion upgrade and others. Car has great power all the way through 6500 rpm and does take a while of getting used to drive on the street. and with a great tune
It still bucks leaving parking lots and car shows. Normal driving it doesn't like to be cruised at much less than 1800 rpms. Cam is made for high rev horsepower but just sounds idles and turns heads. I've seen other less aggressive and easier to drive cams make close to the same power and are more streerable. I made 505rwhp with ported polished milled stock heads vmax throttle body 1-7/8 kooks headers 3" full SW retro exhaust CAI intake ported stock intake manifold and 1 piece driveshaft. If I did it over Again id go less aggressive on cam....... Naa jk I love the car and way it sounds. Hope this helps bud

Jason 98 TA · 11-24-2015, 11:34 AM

I agree with the discussion the 235/239 TSP grind will make power second to none. Here's a dyno sheet of it and the 231/236 on same engine same day!!

Oh and did I mention TSP cam packages are on crazy special?

By looking at that graph it seems that you can choose a slight edge in torque down low w the 231 or a slight gain on hp up top w the 235. They seem very similar otherwise.
Is the 231 a little more friendly in the drivability department?
