Sprintex 335 Testing & Progress

[Xero-Limit]

Turning some laps at NJMP the other day.

Biggest problem? Brakes. First session ended after 10 minutes due to lightning. Second session was wet so no problem aside from having no traction. Final session it was moving pretty quick but 15 minutes into it the brakes were giving up. We put a stop tech kit on it with race pads so should be fine at this point.

Otherwise power delivery was great and the car felt pretty solid with no power fade lap after lap, just needs a proper suspension and a little more seat time on this course. Having done lightning a bunch of times, thunderbolt is a whole different animal with decreasing radius turns and a pretty quick straight. We used the tribodyn supercharger oil.

this might be a stupid idea, but it might be worth it to post it here. I read a lot on this post because i plan on getting the 335 kit for my car in the future. I read a lot about intake temps being to high or people trying to fit a larger throttle body to get more are through the supercharger my plan might eliminate both issues. We all know the colder the the air the more you can fit in somewhere. That's poorly explained, but most of you probably understand it. My idea is to put an intercooler on this kit. I know it already has one in the supercharger itself, but if we put one on like they do on turbos or on the vortech kit it will cool the air an eliminate the problem with the high intake temps. that could also eliminate the need for a larger throttle body with colder means more will get sucked in and be compressed. I do not know if this will work, but its worth a shot to tell some people that can test it out. Hope this helps and feel free to check out my nitrous build thread would love to get some advice on improving my car and my time.

Here's a video of a 210 with the perrin 3" intake and stock plastic tube, if that helps:

1. E85?
2. How much lower is the intake temp with the gold heat reflective tape?
3. Which header?
4. 3" exhaust and which one?
5. How much did the 3" intake increase HP?

Thanks for answering my questions.

Thanks for answering my questions.

1 -Around E65 on that run.
2 -Peak temperatures haven't changed all that much, but they come down a LOT quicker now.
3 - Nameless
4 - 2.5" exhaust
5 - didn't get a before/after on the intake.

Would the 70mm pulley on the 335 be over-spinning the charger?

you're going to struggle here because the place to put an inter cooler is after your compressor

so you need to space the charger up off its manifold in order to fit an exit and a re-entry pipe into this gap and I doubt theres' the room to do this without cutting a large hole in the hood

it's taken 8+ years since they first released a supercharger kit for the 8th gen Civic Si before someone designed an A2A manifold for a roots/ts blower..

http://mercracing.net/products-page/...rger-manifold/

Jose(Merc Racing owner) designed the a2a manifold and runs one on his rsx with a Lysholm blower --- the only other one I'm aware of just recently got running with a TVS1900 blower(pictured below). He's aiming for 430-450whp at around 18psi..

I wonder how much room there is underneath the blower(basically how much room does the current a2w manifold take up) + hood clearance to squeeze in some sort of a2a manifold...

different platform, but I know we don't have an infinite amount of room to fit things up front either -- nice to see the creativity even tho this car is obsolete now..







Hopefully someone takes it upon themselves like Jose did, to fab up something similar for the FT86 chassis! Dat whine is pretty addicting!

Doesn't it have the same threshold as the 210?

According to @moto-mike, for this kit you take the pulley size and multiply by 100, and that will give you the highest you'd want to spin the motor as far as engine RPM. That would mean you'd not want to exceed 7000rpm with the 70mm pulley.

Hmmm....

My limiter is set to 7650rpm I think...that extra 650rpm shouldn't be an issue really...should it?

75mm @ 7,650rpm = 15,235rpm

72.5mm @ 7,650rpm = 15,769rpm

70mm @ 7,650rpm = 16,307rpm

The "safe" CONTINUOS rpm of the 210 and 335 blower is 15,000rpm. I'm not going to tell you whether or not 1,300rpm momentary over spin is "ok" or not since I didn't build these units. I dont know the wiggle room they left on the table, and I'm sure they(sprintex) aren't going to tell you either.

So basically multiply 2.13 by the RPM and if it's over 15k then you don't want to continuously be at that RPM. Based on the numbers it doesn't seem to matter which pulley you run, you'd never want to continuously run over 7k RPM.

I thought 15k was redline, not safe continuous.... My understanding is that generally you shouldnt run over 80% continuously. So if redline is 15k, you should not run over 12k continuous
