What JRSC setup are you running?

[JRSC•GSR•EG]

that lht thing is so over priced, did you re-dyno the car after installing the after-cooler lht thing, does the heat exchange pump just run non-stop or is there like a switch, what did you pay over all, and what motor is it on and did you notice any hp gain from it.

if you look at the dyno numbers people are gaining at least 20 sometimes 40 hp from the cooling effects of the lht manifold.

Its cheaper than buying or building a new engine after you melt a piston or break ring lands.To me it was not at all overpriced for the results I got .Yes I did re -dyno the car after installing the lht .The heat exchange pump can be run to a switch if you desire to shut it off on the highway or can be wired to run all the time mine runs all the time its not my DD and I usually dont drive more than 50 miles at a time .The manifold mod was $795 the heat exchanger kit was $395. I have a jrsc gsr in a 97 hatch putting down 260 hp and 206 trq . I did get hp and trq gains but they came from several items at the same time. I Did a itr exhaust cam , the lht manifold , the lht header , a 3.8 blower nose pulley , and test pipe install all at the same time . I gained 25 hp and 25 ft lbs trq . The LHT cooler makes it possible to make pull after pull and not lose hp and trq due to heat which these things are known for especially at high boost levels .If you look at page 498 of this thread you can click a link and see my before and after dyno charts .

so i looked at the dyno sheets the 1st one looks really ugly mine is no where near that, what psi/other mods did you have then, 260 is where i want to be. i made power up to 8.3k and my final number was 234 or 232 with 173fpt but the motor was on the dyno for a while and i think i could have gotten a little more if i let it cool down, are you running the stock bottom end, what other mods do you have to the motor what header are you using. what psi are you at now


i hardly drive mine to, like just weekends and here in florida its really really hot, i guess i will just save my money for LHT thing post a pic of the set up if you can

[JRSC•GSR•EG]

i will try to post a pic of my dyno sheet soon but i can tell you the car made power and climbed fast up to 7k at 7k the car made 220/167 at 8.5k the car made 234/173 so i only get 14 more hp from 7-8.5k all because of the heat from the charger at least thats what i think

What do your IATs look like above 7k?

As far as mods well the engine is stock from the valve cover to the oil pan other than the itr exhaust cam . I am running the LHT I/C, the LHT header ,3.8 nose pulley ,mvm stepper pulley,toda cam gears ,comp clutch lightweight flywheel ,test pipe , precision 680 cc injectors,walbro 255lphhp, a 3" sri ,and I am seeing 13.4 psi but my pulley set up is for 9 to 10 psi . I have several other mods that are not hp related but help the entire set up perform overall .

105 degrees was the highest they got the whole time on the dyno

Pics are on page 504

[JRSC•GSR•EG]

how do you know what the ia temps are they could not tell me that or they didn't tell me that

[nextproject97]

they data log while on the dyno

Mine at 13psi without the lht are over 200.

I think i have pictures of pulley befor i installed my motor with blower, i will try to put it here tomorrow

[JRSC•GSR•EG]

mine must be high, where does it get dangerous 200 seams like a whole lot i have a data logger in my ecu can i just find some one with tuning software and check it out

[nextproject97]

theres proof in the puddin for the lht I/C thats a big differnece in temps. I have said it a few times but I'll say it again my engine use to ping after a few pulls it scared me . I would also get tip in a quick ping / spark knock when stabbing the throttle. Since the lht its gone no tip in detonation and no ping pull after pull and believe me I listen to my engine carefully .

how many psi are you running and what motor

180 degrees is usually where detonation starts. My ecu retards timing to keep it from detonating.

[Alezhik]

if i will run 14psi on my JRSC how do i cool my IHT? what do i install or what do i do? Any help please

I get those problems too. Started saving for the lht stuff a few weeks ago.

200 seems high I dont know what is considered dangerous because I am not a tuner but I would think 200 is pushing it mine were 180+ prior to the LHT . I would think if your ecu has data logging you should be able to find out easily what you intake temps are. I gotta get to sleep its after 2 goodnight !

its a stock gsr at 13 psi

what is LHT?

Its a modification to your intake manifold that cools the intake air coming into the engine . The company that makes them is called lht performance http://www.lhtperformance.net/

thank you guys

[Alezhik]

actualy LHT cost alot, i guess i have to save some money to get it
