Thunder Racing CheaTR setup
Thunder Racing CheaTR setup I am wondering about this setup, I seen it in this thread(https://ls1tech.com/forums/generatio...-c-set-up.html) but dont want to hijack the thread. Does anyone have dyno number on there car for this setup? I am thinking about doing it for my winter project, any tips or suggestion would be good
im pretty sure there is a dyno graph on thunders website. They are a straight up vendor you wouldnt have to worry about them smudging numbers. The two or three i remember seeing maybe 400-410 whp and 390-405 wtq
its a great h/c setup that you could throw on and just forget about.
I almost went with it because i ahve emissions to worry about here in CA but that was before i blew up my stock motor and decided to get ready to go max efffort

I'm kinda curious myself (don't mean to hijack). I must be getting old because the 111 LSA and dumps are getting on my nerves. Thinking about converting to a sleeper set up.
Since the cam is spec'd with stock manifolds/exhaust in mind, would it essentially be better to choose a different cam from the CheaTR? Something that's designed around using longtubes?

I run a 224/222 117 LSA in my 370ci and it is Stealth, but packs 463rwhp/423rwtq

So if someone had full exhaust and long tubes with AFR heads, what kind of cam profile would we be looking at for a stock exhaust note? Currently running 226/232 on a 111 LSA. Car is a DD.

you wont find alot of info on this cam because most guys want a cam with alot of lope so you know they have a non-stock cam. look into a custom grind cam, that might help you find what you are looking for.
obviously theres more cubes in your build, but what kind of heads/CR are you running. obviously its combo over big cam, which is how it should be 
im sure you could get a custom grind cam on a 116-117 LSA with minimal overlap to make a very good stealth cam that would still give you a 50-60 hp bump, heads helping even more obviously.
I emailed TR about that cam and they answerd every question I had but one! They would not tell me how much power (roughly) The cheaTR cam would make? There is no dyno graph on the website for that cam either. So I said screw it and started lookin at other options, good luck!

This should answer all questions...Pat don't know if you mind I post this up, but I think its good for the masses to see.

I had put this cam in my supercharged car with ported 241 heads for the sleeper look and sound it picked up 140RWHP and 115RWTQ I know its a supercharged car but I still loved the stock drivability

Unfortunately I was unnable to get that combo to pass strict emmissions and yearly test.
I wanted to put the car back on the street so I designed that cam around that criteria.
Combo:
K&N FIPK GenII
Stock MAF
80mm BBK (ported)
85mm LS6 intake (custom mouth, early TPIS prototype)
PRC 5.3L stage 2.5 (2.04/1.575 valves), custom VJ and bowl blend, 4.00 bore chambers, aftermarket intake seats), they were early version PRCs and had to be improved.
Cam 224/222 .604/.581 117+0 LSA, advanced +2 (XFI/XE-R)
GM MLS 6.0 gaskets
Mac midlength (custom modified/cleaned)
Custom catted y, Flowmaster merge, cutout, into 2.5 I into stock muffler.
FLT stage 5 4L60E, Vig 3800 stall, 3.23 gears.
12:1 SCR, 9 DCR runs on 94 octane, 24* max timing at WOT.
All in all, Super Stealth, free flow at flick of a switch, emmission compliant, very responsive throttle response, 400lbs of trq at 3400 rpm, shift points 6600.
Some of the parts I've had on it since 2001, would benefit from LTs, better heads etc... but the sum of all parts works well together.
Also 22>24mpg Hwy if I don't lean into it. (not that it matters gas is relatively cheap here $1.85/ gallon premium.
Once I complete my All bore 396 LSX, it will go back to drag in race weight form, shooting for 9s NA (but that is at leat 1 year away
)Sorry for semi
but it give an idea of Stealth setups. Last edited by PREDATOR-Z; Sep 3, 2009 at 08:21 AM.
