The Best Mod For The GR Corolla's (Intercooler Comparison)

[@CSFracing]

Nice video guys - here is some context and answers to some of the questions or feedback that you raised. 1) The larger inlet / outlet is for guys who want to go bigger power in the future - we're future proofing the design so guys can buy 1 intercooler and grow with the set-up. 2) The powder-coating is a thermal dispersion coating + it helps with avoiding corrosion , debris, etc 3) The frontal surface area allows for the quickest temp drop after beating on it - we have dyno video on our website to supplement the R&D that we did.

[@nicrandazzo758]

OTL was a steal at preorder pricing, they also offer larger tubing as an additional purchase

The OTL is a steal at $600 lol

We are Trying lol. When you want to buy parts DM me on Instagram I can save you some money @john_pharaoh

[@devinsibiski2910]

Glad to see I made a good choice in the OTL intercooler preorder, I may be getting a tune sooner than later since you all said valve float came in with just the intercooler and other bolt-on's. I have the SXTH intake, OTL downpipe, RK Ti catback, and when OTL fulfills the preorder intercoolers I'll be installing that with their intercooler piping as well. Should be fairly close to your moms GRC so I'll hit you up about a tune soon.

[@NemtecRacing]

Yeah with all those mods you definitely need a tune. The lower restriction intake and intercooler will definitely change the AFT enough to affect the car

[@copperkeyracing6167]

Should be getting close to your mom??? That's what your mom said!😂

[@gabea.458]

I'm believe CSF said in the MotoIQ video that the coating helps dissipate heat.

[@copperkeyracing6167]

Sounds like the OTL is the one to get on stock turbo, and the STM on big turbo... and you need to change out the valvesprings like yesterday!

I recognize that fin design on the stm intercooler. It’s a garret core and they are expensive but they are the best cores you can buy. Only draw back is that it can cause over heating if you have a car that has bad air flow to the radiator but they are super popular in the Mitsubishi community.

[@Overseerdv]

@Nemtec, Per your comments on valve-float with all these options beyond stock; what's your recommendation to do about the issue if going OTL or CSF - just stay off the limiter, consciously stay under 6k rpm, or look toward a tune to set rpm limit? My aim is to relieve the components of the heat soak and stress to the engine overtime - keeping the car overall in its stock form long-term means swapping valve springs is a bit overboard. Keep up the great content.

[@GRCDriver23]

Was hoping you would review the sxth element intercooler and charge pipes as part of this

[@PodarujDobro]

Dear colleague, please tell me, if I buy a GR Corolla, where should I start with tuning to achieve 400-450 horsepower and good suspension for driving on snow and gravel, aiming towards a WRC style rather than a racing car?

[@NemtecRacing]

Lamspeed turbo kit with a Garrett g-25 550 turbo. Is what you’ll need to make 400hp. Annex suspension is going to be coming out with a rally cross coil over soon.

[@cheeko_914]

Could you guys do a comparison like this but with intakes? Seems like all the claimed power gains are inconsistant in between companies for their intakes. Some do their measurements in STD vs SAE (like you mentioned in another video), some dont mention if they dynoed in AWD or FWD, and others dont have dyno sheets at all. I feel like companies like K&N are gonna have a lower actual power gain vs other companies like Eventuri or MST. Without consistant testing, their numbers are meaningless in comparison to other companies.

[@zachthomas5148]

Did yall disconnect the rear wheels so it was fwd only?

[@NemtecRacing]

Yeah you can do alittle pedal dance to disconnect them. We do it just cause it causes less wear on the drivetrain

[@KN-jw7ts]

3 of them?! Lol. Awesome.

[@NemtecRacing]

Hell yeah brother just wait till you here the plans for then

[@KoalaOalaJones]

Hey just to clarify: there is valve float on all aftermarket intercoolers because all of them increased boost pressure passed the valve springs tolerance/rating. If I remember correctly from another video, valve float happens on our cars at around 27psi of boost. Sooo can I assume that all of the intercoolers in this video will most likely increase boost passed 27psi during daily driving? It seems like a lot but I’m not an experienced mechanic just a hobbies so I might be missing something here.

[@NemtecRacing]

It’s a tricky question because technically with a tune you could get the stock car in stock form to float the valves… And I wouldn’t run an intercooler without a tune because it’s just not gonna be super safe for the car in the long run idk just my opinion. But the smaller intercoolers on a stock tune probably won’t have valve float. The big intercoolers probably will it the big intercoolers on a stock tune are unrealistic because you need a tune when changing the air flow that much

[@KoalaOalaJones]

Thank you so much for the quick response! Doesn’t valve float correlate directly with high boost pressure though or am I wrong there? Edited this just now to try to make more sense

[@NemtecRacing]

@@KoalaOalaJonesit does but valve float only happens near redline. And honestly most times cars on stock valve springs tapper to somthing like 22psi at redline.

Gotcha. Thank you again for the replies

Hello! Is there any solution for exhaust valve delete? I put a magnaflow exhaust and had some problems with the valve, so i get rid off the valve. I already have a EcuTek tune, but cant delete the warning on the dash of not having the valve connected. Sometimes it appear depending on the throttle pull…

[@NemtecRacing]

You have to have the valve plugged in and zip tie it up out of the way but it still need to actuate or you’ll still get the warning

Yes but intercoolers we recommend a tune. If your ever interested we sell tunes for $1200. Intercoolers are so much more efficient it might be unsafe to run an intercooler in without a tune for an extended period of time

12:25 so you are saying if you get any of these intercoolers and don't get a tune you will run into valve float issue? so technically, they all require a tune to run safely if you are going to track your car, correct? Awesome video as always! I've been waiting for this comparison.

[@NemtecRacing]

Yes sorry I should’ve made it more clear. We would recommend a tune to run an intercooler.

[@elantran]

@@NemtecRacing Gotcha! Another thing I want to ask is that you said the test was done in your mom's CE. Did it have any other modifications during the testing (perhaps the down pipe and intake from previous videos) I'm asking because the baseline torque seems pretty high at 295. I also noticed the peak boost was 29psi which is higher than a stock tune?

Did you guys monitor coolant temps as a part of this testing to test differences? Specifically curious about that due to some of the taller intercoolers you tested potentially blocking up free flow of air across the radiator vs the stock FMIC, and warmer air flowing across the radiator as a whole.

[@mhk67091]

SXTH claims you can run their intercooler and their charge pipe kit on stock tune. Since boost isn’t increased will valve float still be an issue at stock boost levels (not increasing boost).

[@NemtecRacing]

Probably not. But doing mods like this with out a tune isn’t recommended..

[@mhk67091]

You guys said valve float is that with a tune and intercooler or stock with intercooler. And is the OTL unit a bar and plate or tube and fin. I know the CSF is tube and fin.

[@NemtecRacing]

we tested it with a tune and intercooler. but i wouldn't run one of these intercoolers without a tune. they are so much more efficient you'll risk changing AFR to much etc

[@copperkeyracing6167]

My feelings from all the Yaris testing in Austraila... valve springs should be your 1st mod. If you don't, it's a ticking time bomb... even stock... could even be why that gr corolla burnt to the ground recently

[@denstoj]

Oh and how was the throttle response with the STM?

[@NemtecRacing]

There was no change really

[@LoveLikeaHurricane]

So only consider this....when you go big turbo. If you stay stock , and not tune the ECU....no valve float issues. But if you stay stock and use intercooler....still valve float issues?

[@NemtecRacing]

Valve float on these cars is very simple. If you run above like 24lbs of boost past 6k rpm on the stock valve springs they will float

Thanks for all your sacrifice and hard work for for the sake of the GR community.

[@NemtecRacing]

If you bolt on a intercooler you shouldn’t get valve float. But once you get more than one or 2 mods like intake and downpipe we’d recommend a tune cause these cars are sensitive and you can definitely drive your car and daily it with mods and no tune but taking it to the track and ripping it probs isn’t a great idea without a tune

[@NemtecRacing]

Valve float is avoidable by any tuner who knows what they’re doing. If you get a tune you shouldn’t be worried about valve float cause the main guys that tune these cars know what’s up and have the tunes dialed in enough to avoid valve float.
