1LE off to JTM MOTORSPORTS in Long Island

well i just got home from dropping off my 14 1LE camaro at JTM motorsports in LI NY @ 430 pm they share the shop with ARH headers..my car has only 390 miles on and so John from JTM talked me in to transforming it in to a beast…Its getting ARH long tubes and x pipe and were keeping the NPP mufflers . It will also be getting a VENGEANCE RACING Kaotic cam with melling HV oil pump .BTR double valve springs with titanium retainers ..3 bolt cam gear and C5R timing chain along with a tune ..I am a bit nervous to be honest as the car was darn near perfect stock but oh well its on now .. i will keep you posted how it turns out or you can go to JTMMOTORSPORTS on Facebook and check it out as he baselines it then tears it down …I hope i did the right thing …LOL
IN all honesty beside me being a wussie ..this shop is top notch here on the ISLAND ..Also would like to say that dealing with Vengeance racing for parts was awesome too ..the were very kind to take time to give me advise and listen to my stupid questions and shipped everything out very quickly ...

I think your gonna be Fine!
But do yourself and that car a huge favor
Put the Dewitt's or Ron Davis radiator and the lingenfelter thermostat in it while they have it apart

Why? I did a Lingenfelter cam/heads upgrade and have had zero heat issues. Its not even been a consideration so I am wondering ...what do you know??? lol

JTM are good people. Even though I don't work for ARH anymore, I still keep in touch with Nick at ARH and John at JTM. I actually have used John in the past to work on my cars before he had JTM. I'm thinking about ordering a 1LE and doing a blower, cam and headers on it. I saw vengeance got to over 700 wheel with their kaotik cam, ECS blower and ARH headers.

Let me know how it turns out as I am planning on taking Mine there for American racing headers and a tune. I believe that shop belongs to the son of American racing headers.

Looks like you will be tearing up the Island soon with that set up . You don't need to go cooler on the T stat ,just have them set the fans to go on sooner at 175 when they do the tune. Also a Ron Davis rad is always good ,but you don't need one with that set up , in NY . The stock rad works fine here in Phoenix ,where it is really hot. I grew up in Jersey and we used to go out to Baldwin and street race on the Sunrise HW back in the 60's .

update my car was on dyno when i left shop last night around 730 still tuning but so far on a Mustang dyno she put down 472@6800 and 426tq..i don't really know if those are good numbers or not for this set up but it is what it is ..i guess i was expecting more …from this set up but i am new to the ls3 game ..been doing mustangs for 13 years ...

I'd say thats pretty impressive. Bone stock LS3's usually dyno between 380-390 stock. So you probably picked up around 80rwhp.

I don't follow. Given:
Torque x RPM / 5252 = Power

Your numbers don't add up.

Mine:
424 x 5420 / 5252 = 437.56 HP with the HP dropping after 6300 rpm.

Plus the LS3 isn't meant to rev past 6600 rpm, Chevy recommended:
http://www.chevrolet.com/performance...l#installation
Maybe with your new cam, springs and retainers you can rev higher?

Can they explain the numbers?

It's not wierd, it's normal. A more free-flowing exhaust reduces backpressure and the scavenging effect, often below ideal. This has the effect of reducing torque and power at lower rpms, but by allowing the engine to breathe easier and rev higher, it gains power on the top-end. It's actually a less powerful engine that is capable of revving higher, thus making more power (but only at the higher revs).

below 5252 rpm any engine's torque number will always be higher than its horsepower number, and above 5252 rpm any engine's horsepower number will always be higher than its torque number. At 5252 rpm the horsepower and torque numbers will be exactly the same.

also you should ask vengeance racing the same question ..the exact setup on another 1LE they did made 480/430 almost identical hp /tq difference to mine just 10 higher .I guess there numbers don't add up either…there are a bunch of smarter guys on these boards than me maybe they can chime in ..i only saying what i saw on dyno ….

1LE off to JTM MOTORSPORTS in Long Island

JTM is saying the HP is 472 with torque of 426 at 6800 RPM.

Torque x RPM / 5252 = HP

426 x 6800 / 5252 = 551.56 HP.

But why is JTM's number lower.

maybe you dyno on a different dyno and the numbers are different due to that..actually we came up with engine hp of 556 fly wheel

look at everyone who dyno's this combination there all with in 10 of my #s hp and tq with with an average spread of 55 between hp and torque ..i don't have an answer call him and ask he is a super nice guy sure there is a reason ...

That's cool. So the numbers seem to line up. So is the 472 meant to be at then wheel then? Check this site out.

http://www.1728.org/mtrtrq.htm

Using the HP numbers he gave you your torque is 364.55. But at the torque and RPMs he gave you the HP is 551.56.

Please don't take my questioning as being combative. I just had headers and a tune done too. Separate from the different ways to measure torque and RPMs (different types of dyno tools and where the reading is taken, wheel, crank, flywheel) I believe the formula for calculating HP is the same unless I'm grossly mistaken.

Ok. Then ask them why the HP is low given the torque and RPMs. Something doesn't add up.

Id say you are on par with everyone who run the same cam. Just depends on the dyno/ weather then.

What mustang were you tuning and what numbers you where used to? There is not so many cam only N/A engine from Ford who runs like LS series with stock internals.

LS1 were spinning to 7200rpm in 1998'...Sure its best to spin not too high for reliability, but when you swap cam you live with your decisions. Pretty sure anyone who mod their car knows that. LS3 Lifters/heads/intake arent the problem for revving higher..maybe the stock pistons and bearing arent meant for that. Id say 6800 is the max Id want to go.
