EGT's Don't bash me

[Afroclipse]

OK just so we all now I'm 100% dsm and thats what i drive but i have a question involving by buddy's ride, He has a fully built honda prelude top to bottom t3 turbo 2.25 fmic piping vortech bov turbo kit too be exact, log manifold power fc gauges the whole works. His engine can handle over 500 horses but when he went to have is car tuned and dynoed they only got 297whp out of it. According to the shop his EGT's where to high and they could get more horses until they were lowered. According to my Honda buddy he wants to go 2.75 fmic piping bigger injectors, bigger intake manifold Q45 throttle and 44mm wastegate. I have limited knowledge about EGT''s everything i know i got from you guys so the question is will those mods drop egt's or If not what would. I said don't bash me because i know how you guys feel about ricers.

The only one of those mods I can see that would adequately influence EGT's is the larger injectors. With the information you're telling me, I can only assume certain things; I cannot make 100% judgments on anything. That being said, I would assume his air/fuel ratios are very lean. This is due to not enough fuel for the amount of air going through the engine. When the ratios are too lean, it makes the exhaust get very hot. So his EGTs would go up due to being lean. The larger injectors allow more fuel to be injected, so the larger injectors may lower the EGT's.

Tuning will lower his egt's. If they were high thats ususally means he is running lean (or stupid rich). Changing parts will effect that. Maybe he does need bigger injectors, but if he is running lean he should turn down the boost.

Just because he drives a Honda doesn't mean he is a ricer

Agreed, most of the time like 99% of the time if EGTs are so high it means he is running super lean, so the other crap isnt gonna help him maybe even hurt him. I would suggest injectors, fuel pump and a FPR.

He has 390cc, 34mm wategate, so it really doesn't matter how tough the engine is (manley rods, wiseco piston, ferrea retainers e.t.c he's got it all) as long as the setup is it right your egt's will still be high.

Just because someone drives a Honda, it doesn't necessarily make them a ricer.

High exhaust temperatures could mean that he may not be burning fuel that efficiently, his air/fuel ratio could be off, he could have any number of problems.

 

[Afroclipse]

fuel gauge is at STOICH, oh yeah not to start anything if you notice anytime the H word is mentioned somebody shouts out RICER.

 

[Loco4Life]

Not everyone here is a Honda hater. There are plenty of respectable Hondas and Honda drivers.

 

[brute]

There are plenty of ricers in every make and model. Neons, Hondas, Cavaliers, heck, even DSMs. Ricer is a state of mind, not the make and model of their vehicle.

Is he using a wideband o2 sensor or just the dyno's sniffer?

 

[endeffect0]

where is he geting his AF ratio from? ECU, narowband, wideband, im assuming their going by his gauge and their may be a problem with his hook up... also what are the rest of the gauges he has doing? does he have water and oil temp???

 

[Afroclipse]

OK OK OK, i guess this RICER issue has hurt a lot of virginas , so as of right now "I AFROCLIPSE will refrain from any use of the word RICER in any shape or form" . Back to the issue, he used the dyno sniffer i'm not sure where he has his A/F gauge connected and no water and oil gauge (unless your counting the factory gauge)
I really want to know the best EGT lowering remedies.

 

[brute]

Well, there are many different causes of high EGT's. He's going to need to narrow down the possibilities. If he is using a narrow-band a/f gauge, do NOT trust the readings from it. They are not accurate and will mislead you.

youre the one that brought it up, so umm, yeah. ricer

sounds like a tuning issue, if his EGT's spike its due to leaning out, he needs more fuel or needs to lower his boost to save his motor until he can afford to add better fuel delivery.

larger intake/piping, throttle body and wastegate will have little to no effect on his EGT situation. Bigger injectors are a must though.

 

[Afroclipse]

A tuning shop did his tune i was there when he took it there they told him his eegt's where to high so all the got was 297whp and they said if he got a better flowing intercooler and bigger piping they would be able to get him bigger numbers, then quoted him core and piping prices but thats where he's at now as for me well not to start a thread but a/t to m/t haven't touched it in a week SOB downpipe bolts won't come out

 

[endeffect0]

tell him to take his car to a new shop that doesn't sound at all right to me!

... have you tried soaking those bolts in rust remover or naval jelly worst case cut off the old bolts and go out and get some new ones for the reinstall...

390cc injectors???

Is it just me or does that seem to be SUPER small for that setup??? Bigger injectors/fuel pump/FPR a MUST

 

[Afroclipse]

He has walboro 255, afpr, and 550 injectors not 390's he is also just got a tubular manifold you think its going to save his egt's or is he just wasting money. He is sure that if he can get better and colder air flow his egt's will lower so he can get at least 400whp. What do you guys think.
