S280 vs Stock Low RPM

This is probably a dumb question, but does the S280 still pull harder than stock at low rpm? My stock turbo blew and the S280 is the soonest availability for me.

This is on 91 octane and i have since added 30% injectors and e30 fuel, but you get the point. this turbo makes power everywhere.

What other mods did you have for that vid?

I don't usually floor it at this low of RPM, this is just to show the capability of how quick this turbo will spool.

It’s at 4k that it really starts kicking for me.

I agree you don’t want to be flooring it all the time from 2500 …. though my tuner specifically asked for 2500-7000 33rd gear WOT logs …. so I’ve had to do it like 80 times over the course of the custom 93 and E40 tune with aux fuel development, LOL.

I got the turbo and IC installed. It's pretty neat. It makes some cool, though quiet flutter/whoosh noises even with stock wastegate and bov. I temporarily tried it with my sorta aggressive stage 1 tune and you can spin the tires in every gear. Though now with my stage 3 base tune it feels slower than the stock turbo. Anyway, I'm having electrical issues now with the car shutting off while driving, so that's fun.

Look. For torque, spool time, earlier RPM, the stock BorgWarner has the TurboTechnics beat all day. ALL day. My e30 tune from Dizzy with USD stage 2 parts had over 300 lb-ft (per AP) but it sure as hell felt like it and the spool and ommpf was certainly prior to 3k RPM and pulled harder than the S280 from then to about 5K give or take but is the S280 faster and better overall? Yes. But from low RPM (to me, 4k RPM under), the stock BorgWarner just dominates. Perhaps for perspective, a stock 392 Scatpak couldn't shake me in street speeds with my e30 tune on the stock turbo. I was literally on his bumper and if he braked, I would've hit him closeness. S280 is decent, don't get me wrong, but unless it's a etune on it, the FiST isn't going to see over 300 lb-ft on the stock fuel system.

What kind of tires you running ?

My experience has been the car drives like a stock car down low with the S280 yes it does not spool as quickly as the stock turbo but it also does not run out of steam at 5k it pulls all the way to redline to the point of you can find your bouncing off the rev limiter if going for it.

I have driven a stock turboed car with a 91 tune vs my S280 and literally done a drive one car one day drive the other car the next. I found after owning my S280 powered car and then drivIng a stock turbo car for a few months I missed the mid range tq and pull of the S280. I could hit the gas on the stock turbo and sure initially it had some kick but that falls off very fast. It was depressing.
I eventually got used to it but the minute I stepped back into my S280 powered car it was like oh ya this is what I was missing this thing goes like stink.

If your not feeling the S280 maybe you need a better tuner.


Ya tune+ tuned here and he is the S280 master when it comes to tuning it. My car flies . I do not have problems getting off the light quickly with it and the minute I am at 3k and above it just pulls hard TQ steer yup more than the stock turbo would ever give you.

P.S. you cannot use E30 tunes for proper comparos because e30 is not available everywhere and oh I have run my S280 on E30 with a E30 tune it’s absolutely silly . It’s got a huge donkey kick down low that would shame the stock turbo and a hybrid . I would say if you are gonna compare a stock turbo on a E30 tune you need to compare that to a S280 on a E30 . Ya pushed 340wTQ on a E30 base tune for the S280. 😂
