OK ya, twin turbos are quite the bolt on. But this is no drag race kit with some huge air to water intercooler. It is their street kit that keeps all accessories. The kit made 1,100 rwhp on the base 55mm turbos and ran 8.9 @ 155. The base kit now comes with 62mm turbos. The 1,400 came with the upgraded 64mm turbos.

The car does have a built short block. But has stock intake, stock heads, stock cams and stock automatic trans. The car made that power on E70 @ 29psi. I think that is damn impressive. They hope for low 8's now.

Edumacate me on new mod motors. Aren't the newest 2015 motors forged from factory or at least stronger bottom end wise from the previous year coyotes?

The 2015+ motors have a forged crank. The rods are a "powedered metal" forged rod. People say they are good for about 700-800rwhp. Pistons are not horrible, but again, you would want to swap them out with goals of big power. There are guys making 900+rwhp on the stock motors. So i guess it depends on how big of a risk taker you are. Most would upgrade to an aftermarket I or H beam rod and stronger piston if they plan to make big power reliably.

The heads flow a ton of air. They are basically an as cast version of the 2012-13 Boss cnc heads. Even more port tweaks, larger valves and larger cams help round out the items that help it make power. Even the cam timing is handled a little bit differently.

The ECU in the 2011-14 if very strong. The 2015+ even more so. With more maps that you can count for ignition timing, fuel trims, cam timing, o2 correction and so on. There really is no need for a stand alone anymore. Because you can data log and have the ability to control the motor/car better than any current stand alone out there. I am sure most manufactures have technology like this now a days. Sure makes it easier to modify stuff.

One thing with this kit is that you have to do a lot of wrapping . They mount the turbos in the front. That kit will bolt up to a stock motor . If you're pushing 1400hp or even 900 and the car will be abused you better upgrade . This would easily make any stock motor explode over time .

Only thing that impressed me was that the stock transmission held this power. I doubt it will for long, but even one pull at 1400 is impressive.

Checked the kit out online. People are going to think the base price of $9,000 dollars will get them this power safely. lol

This.

Its great publicity for them and the kit price is reasonable for the power you get, however when you start looking at all the extras that they put into this car..... Better internals, all the wrapping, the labor, the tuning, plus the kit upgrades. I bet your bill leaving the shop would be pushing 20k if not more with all the labor involved and upgraded parts.

And that still does not include the transmission you will need very soon, and the rear end that will eventually give out after a few launches at 1400 HP or Axles.


Would be a good roll race car for a budget though.,

It isn't required but heat management is always a good thing to do with a street car and a turbo kit.Plus it does make the kit slightly more efficient. As far a heat in the engine bay, in a race car it doesn't much matter. Hellion offers ceramic coating on the hotside if you want it. Wrapping it is fine as well. It is stainless and should hold up to the wrap, unlike a mild steel kit.

The trans has been holding up well in big power applications. A few have smoked the clutch pack and a few intermediate shafts have failed as well. They make an upgraded clutch pack as well as a 300M intermediate shaft.

This car is probably going to progress into more of a race car than street car. I have a feeling it might get a TH400 is she continues to run NMRA classes.

The kit not cheap. I am not going to say it is. lol But it is a complete kit, stainless hot side, tuning and so on. Not horrible but not "cheap" for sure. Quality new cars kits are always expensive. The piping is manufactured and fabricated here in the USA. Bassani manufactures the hot side for Hellion. The kit also comes with top shelf parts. You can buy an On3 kit for much less. But that kit comes with bypass valves and wastegates that have been shown to fail. The turbos seem ok but are not nearly as efficient as the Precision turbos. So if you by the On3 kit and upgrade all the stuff it gets up there in price as well. And your stuck with sub par tubing and beyond horrible customer service. So are you really coming out ahead by saving a little?

How much do you think a 1400rwhp LSx race car cost? lol It isn't going to be a stock block, stock headed, stock rotating assembly, stock 4L60E car with a bolt on turbo kit. That is for sure!

Building a race car isn't cheap. But this isn't overly expensive for a 1400rwhp set up so far.

The trans in this car should be every bit as strong as a th400, if not stronger. It has larger drums, larger clutch packs, larger shafts and so on. The limiting factor will be if they can lock up the torque converter at WOT. The "trans break" mod people are doing, basically a couple of relays to lock it in 1st and reverse, isn't nearly as quick as a Pro Tree brake in a th400 or glide either.

The 8.8 has been handling that kind of power for years. The 2015 IRS 8.8 is what Ford calls a "Super 8.8". It has larger pinion bearings, pinion diameter, stronger case and so on. Sure, the IRS is new and I think we will see what fails with this kind of power. But my guess it will be pretty stout. As long as they swap out the case as the stock automatic cars come with an aluminum cases. The manual cars have a stronger iron case.

Well parts for an 02 Trans am will be cheaper of course than a brand new 5.0. It is more or less the labor that will raise the price more than anything. If you are someone who can install these parts yourself you would save Thousands of dollars. If you can do the engine work as well thats even more savings. Most people can't, or do not have the special tools required for that kind of undertaking.

When it boils down to it. Yes all in at 20-25k that is not bad for 1400 hp. Compared to GTR or lambo 1400 HP money. But it will give normal people sticker shock when they find out how much it actually takes to run that power reliably.

Parts for a 02 TA are cheaper. But to make that kind of power you need ALL of them. Block, rotating assembly, heads, intake, cam, stand alone ECU, TH400, driveshaft, Dana 60 or 12 bolt rear end, fuel system and so on. Price of the car aside you are talking a LOT more money to build that 02 TA. If you can't do a motor assembly then it is going to cost the same. Shop hourly rates are not going to change. That 02 TA would cost more at the shop due to the fact that the shop has a lot more to install onto it.

This is a bolt on kit. Anyone should be able to bolt this thing onto their car with basic hand tools. I am sure people planning on making this kind of power have the know how to swap out a long block as well.


This car probably has less modifications as the typical HCI LS car has. Seriously.

I am sure the 2016 Camaro is the same way. I bet we see incredible power with limited mods soon. Minus the cost of the car, you can not touch the power these cars are making for the money. The old stuff is cool, but fuck it is expensive to build. Trust me, I know! lol
